=Detailed changelog between 1.1.8 and 1.1.9 releases=
=Changelog between 1.1.8 and 1.1.9 releases=
==alsa-lib==
===Core===
: - Release v1.1.9
:
: - add support for GCC's LTO
: - add snd_strlcpy() and use it everywhere
:
: - ucm: Add ucm files for DB820c board
:
: DB820c board is based of MSM8996 Qualcomm SoC, which has support for both
: Digital and Analog audio. Digital audio is over HDMI and analog is over
: WCD9335 codec via SLIMbus.
:
: Board itself has HDMI port, a 3.5mm audio Jack and an Audio expansion
: connector.
: This patch adds support for HDMI port and 3.5mm jack.
:
===Control API===
: - add support for GCC's LTO
: - Print unsigned ints with %u instead of %i. (snd_ctl_ascii_elem_id_get)
:
: - add snd_strlcpy() and use it everywhere
:
===PCM API===
: - add support for GCC's LTO
: - pcm: multi plugin: reset hw/appl pointers in prepare/reset functions
:
: - pcm: multi plugin: detach the hw_ptr and appl_ptr from master_slave
:
: Unfortunately, the master_slave buffer pointers are not always in sync with
: the presented avail value and the higher layers (like write_areas) got
: confused. Create own hw_ptr and appl_ptr.
:
: This commit also tries to fix the hwsync and delay implementation (iterate
: through all slaves).
:
: The multi plugin was designed only for hardware which runs really in sync.
: Anyway, users are trying to use this plugin for other purposes.
:
: - pcm: fix wait condition in snd_pcm_write_areas() to avoid return zero
:
: The hw_ptr might be updated during the snd_pcm_may_wait_for_avail_min() call,
: so even if it returns zero (OK), the avail must be updated again.
:
: - pcm: multi plugin - fix wait_for_avail_min
:
: All slaves should be asked to wait otherwise the write loop might
: be interrupted and zero frames might be returned.
:
: - pcm: null: Do not allow a period size of 0
:
: Some applications do not expect that get_period_size_min() could
: return 0. Therefore these applications cannot use the null plugin without
: this patch.
: Due to there is no use case for having a period size of 0 this patch
: disallows a period size of 0 when using the null plugin.
:
: - pcm: rate plugin - fix signess in snd_pcm_rate_avail_update() comparison
:
: - add snd_strlcpy() and use it everywhere
:
: - pcm: add the missing <strings.h> include
:
: To define the prototype of ffs. See 'man ffs'.
:
: - pcm: dshare: Fix overflow when slave_hw_ptr rolls over boundary
:
: In snd_pcm_dshare_sync_area() when 'slave_hw_ptr' rolls over
: 'slave_boundary', the wrong variable is checked ('dshare->slave_hw_ptr' vs
: the local 'slave_hw_ptr'). In some cases, this results in 'slave_hw_ptr'
: not rolling over correctly. 'slave_size' and 'size' are then much too
: large, and the for loop blocks for several minutes copying samples.
:
: This was likely only triggered on 32-bit systems, since the PCM boundary
: is computed based on LONG_MAX and is much larger on 64-bit systems.
:
: This same change was made to pcm_dmix in commit
: 6c7f60f7a982fdba828e4530a9d7aa0aa2b704ae ("Fix boundary overlap”) from
: June 2005.
:
: - pcm: Preserve period_event in snd_pcm_hw_sw_params() call
:
: snd_pcm_hw_sw_params() in pcm_hw.c tries to abuse the reserved bits
: for passing period_Event flag. In this hackish way, we clear the
: reserved bits at beginning, and restore before returning. However,
: the code paths that return earlier don't restore the value, hence when
: user calls this function twice, it may pass an unexpected value.
:
: This patch fixes the failure, restoring the value always before
: returning from the function.

===Sequencer API===
: - add snd_strlcpy() and use it everywhere
:
===Timer API===
: - add support for GCC's LTO
===Topology API===
: - Close topology config file after parsing it.
:
: - add snd_strlcpy() and use it everywhere
:
===Use Case Manager API===
: - Android: avoid using versionsort
:
: Android doesn't have versionsort yet.
:
===/include/Makefile.am===
: - Drop -I$includedir/alsa from alsa.pc
:
: We used to put the additional include path $includedir/alsa in
: pkgconfig just because some applications have included asoundlib.h
: like
: #include <asoundlib.h>
: although the canonical form should be
: #include <alsa/asoundlib.h>
:
: However, adding this include path is significantly dangerous due to
: possible conflicts of file names like version.h. It's already the
: reason to discourage people using alsa.pc for the packages.
:
: In this patch, the additional include path from alsa.pc is dropped
: finally. At the same time, as a rescue plan for the programs
: including via <asoundlib.h>, a stub header file is provided in
: include/sound/asoundlib.h. It just includes alsa/asoundlib.h with a
: warning to suggest for replacing with alsa/asoundlib.h.
: Actually this is the same file as we install into sys/asoundlib.h, so
: the whole changes are very minimal here.
:
===ALSA Lisp===
: - alisp: add the missing include
:
: Commit d4e08c5e865 changed to use internal versioned functions.
: However, the header is not included. It generates the errors:
:

===Configuration===
: - Android: avoid using versionsort
:
: Android doesn't have versionsort yet.
:
: - conf: pcm dmix - add CHANNELS argument
:
: It seems that some audio devices do use only mono audio for some
: applications (RPi).
:
: - ucm: bytcr/PlatformEnableSeq.conf update some comments
:
: Commit f91cc3c7d6b7 ("Update chtrt5645 ucm variants to use
: bytcr/PlatformEnableSeq.conf component") updated the
: following 2 comments:
:
: # codec0_out settings (used if SSP2 is connected to aif1)
: # modem_out settings (used if SSP0 is connected to aif2)
:
: Specifically it added the " to aif1" resp. " to aif2" part of the comments.
:
: This is not correct, AIF1 / AIF2 are something which is present on
: Realtek codecs only, and either one can be used indepedent of
: SSP0 or SSP2 being used (the comments in the chtrt5645 UCM profile
: before this change were wrong / outdated).
:
: Besides there not being any relationship between SSP0 or SSP2 being
: used, bytcr/PlatformEnableSeq.conf is also used with other codecs,
: e.g. the ESS8316 codec where this is not applicable at all.
:
: Therefor this commit removes the " to aif?" part of the comments again
: to avoid confusing people reading this in the future.
:
: - ucm: Add ucm files for DB820c board
:
: DB820c board is based of MSM8996 Qualcomm SoC, which has support for both
: Digital and Analog audio. Digital audio is over HDMI and analog is over
: WCD9335 codec via SLIMbus.
:
: Board itself has HDMI port, a 3.5mm audio Jack and an Audio expansion
: connector.
: This patch adds support for HDMI port and 3.5mm jack.
:
: - Revert "conf/ucm: Add a UCM profile for Dell WD19 Dock USB-audio"
:
: This reverts commit d8013619c942dd996c32337a9ade429bfaf455ee.
:
: The USB driver defines identical profile as for WD15.
:
: - conf/ucm: Add a UCM profile for Dell WD19 Dock USB-audio
:
: USB-audio device on Dell WD19 docking station provides two individual
: output PCM streams, one for headphone Jack and another for speaker out
: Jack. A UCM profile gives the proper roles for these.
:
===Dynamic Loader helpers===
: - add support for GCC's LTO
===Error handler===
: - add snd_strlcpy() and use it everywhere
:
===Test/Example code===
: - Printf unsigned longs with %lu instead of %ld (playmidi1.c)
:
: - Printf unsigned ints with %u instead of %i (pcm.c)
:
: - Printf unsigned long longs with %llu (mixtest.c)
:
: - Printf unsigned longs with %lu instead of %li (midifile.c)
:
: - Printf unsigned long with %lu instead of %li (latency.c)
:
: - test/latency: use frame bytes correctly in writebuf()

===Utils===
: - Drop -I$includedir/alsa from alsa.pc
:
: We used to put the additional include path $includedir/alsa in

: like
: #include <asoundlib.h>

: - axfer: Declare global variables as 'extern' in header
:
: This avoids multiple definitions of the same global variable (one in
: each file that includes this header), and fixes a linking error when
: compiled with -fno-common.
:
: Fixes: 96110793b3e5 ("axfer: add support for a container of raw data")
:
: Reviewed-by: Takashi Sakamoto <o-takashi@sakamocchi.jp>
: - axfer: Fix creation of v1.2 headers on big-endian systems
:
: struct block_v120_format defines these members as uint8_t. On
: little-endian systems, no swapping is done, and the generated block
: header is fine. However, on big-endian machines, the value is swapped to
: the high byte and then truncated by the assignment, causing both
: bits_per_sample and samples_per_frame to be zero.
:
: This fixes an assertion failure in container-test when later
: parsing the header ["assert(*samples_per_frame > 0);" in
: container_context_pre_process()].

: FTBFS for unit tests of axfer.
:
: This commit fixes to add it.

: Fixes: b878df1ff0b0: ('axfer: add unit test for container interface')
: Fixes: 39d1ab8a0cb4: ('axfer: add a unit test for mapper interface')
: - axfer: allow to be compiled with glibc-2.11 or former
:
: The program, axfer, was developed in userspace with glibc-2.28. This
: userspace is mostly compliant to POSIX:2008 and some additional macros
: for poll event are officially available. The glibc supports them as a
: default since its v2.12 release. It will be failed to be compiled with
: old glibc or the other libraries for C standard APIs.
:
: One of the purpose of axfer is an better alternative of aplay. In a
: point of the purpose, it's preferable to be compiled with the old
: libraries.
:
: This commit adds conditional macros to be compiled with libraries for
: old compliance level of POSIX.

: Reported-by: Jay Foster <jay@systech.com>
: Fixes: fce16d9279b6 ('axfer: add an implementation of waiter for select(2)')
: - axfer: correct invalid usage of escape of itaric text
:
: A dot sign is valid for a prefix of instruction.
:
: - axfer: supplement value of options for the manual of transfer subcommand
:
: This commit supplements value of options for the manual of transfer
: subcommand.
:
: - axfer: correct message to notice that help text is implemented
:
: Now help message is available to give help option to command line.
:
: - axfer: correct description about snoop mode of libffado
:
: The libffado library can listen to isochronous channels to which unit on
: IEEE 1394 bus transfers packets as long as the unit allows software to
: read the channel from its register.
:
: This commit corrects description about snoop mode.
:
: - axfer: fulfill section for backward compatibitity for chmap option
:
: At present, axfer losts backward compatibility to aplay in a point of
: 'chmap' option.
:
: This commit filfills a section to describe lose of backward compatibility
: of chmap option.
:
: - axfer: add a section about unit test
:
: Two unit tests are available to check internal implementation of axfer.
: They perform file I/O for many times and take much time to finish.
:
: This commit adds a section about it.
:
===alsa-info.sh===
: - alsa-info.sh: cleanups
:
: - fix awk arguments
: - backticks/gravemarks removal
: - some cosmetic and indentation changes
: - add REQUIRES to check the basic tools
:
===alsaloop===
: - alsaloop: remove unused assignment warning (coverity)
:
===alsamixer===
: - alsamixer: define _GNU_SOURCE to get exp10
:
: Fixes Master, Headphones and Speaker stuck at -8 percentage after
: building with Clang 7.0.1 and getting warned about implicit declaration
: of exp10, which is behind _GNU_SOURCE as a non-standard feature. Thanks
: Takashi Iwai for the CFLAGS suggestion on the mailing list. GCC build is
: not affected, so not adding a compiler check to the configure script.
:
: uClibc-ng has got exp10 since 1.0.12, so the fallback macro is no longer
: needed. However, alsa-utils relies on gettext so might need further
: patches to actually work on uClibc systems.
:
===amixer===
: - amixer: define _GNU_SOURCE to get exp10
:
: Get rid of a warning about implicit declaration of exp10, which is
: behind _GNU_SOURCE as a non-standard feature. The same problem was fixed
: for alsamixer in commit 116488e5f2f1b897084bd151381ee254e1cc177d.
:
===aplay/arecord===
: - aplay: check the return value for snd_pcm_sw_params_current() (coverity)
:
: - aplay: fix the multiple open file descriptors for the raw capture
:
===aplaymidi/arecordmidi===
: - arecordmidi: simple coverity fix
:
: - seq: arecordmidi: Add num-events option
:
: Add a command line option to automatically exit after recording a fixed
: number of MIDI events. This allows a program using arecordmidi to expect
: a MIDI file to be written automatically when the specified number of
: events have been received, instead of having to send a SIGINT or SIGTERM
: programmatically.
:
: It also avoids the need to have the arecordmidi process running in the
: background, and then constantly stat the output file to check if any
: bytes have been written to it (this makes for less predictable and
: longer-running tests).
:
: This functionality finds use in Chrome OS functional testing, since
: having to send SIGTERM/SIGINT programmatically and then wait for the
: output file adds unpredictability and delay to the tests.
:
: The addition of this command-line option should (hopefully) not break
: any existing usage.
:
==alsa-plugins==
===Core===
: - Release v1.1.9
:
: - configure: Fix unexpanded ALSA_DATA_DIR
:
: When no --with-alsadatadir is given, configure scripts takes
: $datadir/alsa as the default location, while it's expanded to
: $prefix/data/alsa. Although ALSA_DATA_DIR is set via
: AC_DEFINE_UNQUOTED(), this expands only $alsadatadir itself and not
: about the $prefix in the content. For resolving this, we need to do
: eval twice.
:
: - configure: use $sysconfdir instead of /etc
:
: Use $sysconfdir as prefix for ALSA_LCONF_DIR by default. Otherwise install
: fails on non-FHS distros.
:
===Alsa support for Maemo SDK (n770)===
: - maemo: Fix a few crashing bugs
:
: maemo plugin has two crashes I was able to see in a valgrind log from
: another user:
:
: * maximum write size was calculated in words (16bit), but checked against
: byte-size length. This causes memcpy later to overflow the buffer
: (normally by up to 12KB).
: * remove a double free (by marking free'd data with NULL)
:
: * mmap returns MMAP_FAILED on error, not NULL
:
: I suspect that this plugin/driver might have other issues aswell, since I
: am unable to find any logic for checking DSP buffer status, and no
: implementation for odelay reporting.
:
===Documentation===
: - doc: Add forgotten aaf.txt to EXTRA_DIST
:
===Jack PCM plugin===
: - jack: use correct port names in 50-jack.conf
:
: Change port names in 50-jack.conf from "alsa_pcm" to "system".
:
: JACK1 v0.125.0 still provides alsa_pcm:playback_* and alsa_pcm:capture_*
: port names, but only as aliases:
: $ jack_lsp -A
: system:capture_1
: alsa_pcm:capture_1
: system:capture_2
: alsa_pcm:capture_2
: system:playback_1
: alsa_pcm:playback_1
: system:playback_2
: alsa_pcm:playback_2
:
: JACK2 v1.9.12 doesn't support alsa_pcm:playback_* and alsa_pcm:capture_*
: aliases anymore, so 50-jack.conf will fail for JACK2 users:
: $ jack_lsp -A
: system:capture_1
: alsa_pcm:hw:0:out1
: system:capture_2
: alsa_pcm:hw:0:out2
: system:playback_1
: alsa_pcm:hw:0:in1
: system:playback_2
: alsa_pcm:hw:0:in2
:
: As you see in both cases system:playback_* and system:capture_* are
: correct port names.
:
: - jack: Support to connect multiple JACK ports with same ALSA channel
:
: The following example will connect ALSA channel 0 to JACK port
: "system:playback_1" and "system:playback_3" and ALSA channel 1 to JACK
: port "system:playback_2" and "system:playback_4":
:
: pcm.jack {
: type jack
: playback_ports {
: 0 [ system:playback_1 system:playback_3 ]
: 1 [ system:playback_2 system:playback_4 ]
: }
: }
:
: The old syntax with only one port for one channel is still supported:
: playback_ports {
: 0 system:playback_1
: 1 system:playback_2
: }
:
: Without this patch an additional JACK client has to be used to
: automatically connect the second JACK port but this could take some
: time. Therefore it misses for example the first audio period on the
: second port.
:
: - jack: Refactoring: Lower indentation
:
: to full fill 80 character limit of next commit.
:
: - jack: Removing snd_pcm_jack_format_t as it is not used
:
: - jack: Replacing jack->channels with jack->num_ports
:
: As jack->num_ports and jack->channels hold the same values,
: jack->channels is redundant and hence removed.
:
: Sanity check is added in prepare, to check if io->Channels is
: same as jack->num_ports.
:
: - jack: Moving jack_deactivate() to snd_pcm_jack_hw_free() to speedup the XRUN Recovery
:
: Removed snd_pcm_jack_stop() from snd_pcm_jack_prepare(),as on XRUN we do
: not need to reconnect or reconfigure anything.
:
: - jack: Move jack_activate() and jack_connect() to snd_pcm_jack_prepare()
:
: Since the processing of jack_activate() and jack_connect() take a while
: longer, snd_pcm_jack_start() was blocked.
: Consider a usecase of reading the data from capture device and
: writing to a playback device, since the capture device is
: already started and the starting of playback device is blocked,
: it leads to XRUNs for capture device.
: Therefore these calls are moved to snd_pcm_jack_prepare(),
: So that the capture and playback devices can be prepared in advance so
: that starting of the device doesn't take too long.
