Amlogic DPCM audio card(s) speaker placement issue
by Christian Hewitt 10 Dec '21

10 Dec '21

Hello alsa-dev / linux-amlogic, I’d like to describe a problem with speaker placement seen with the Amlogic (meson) AIU and AXG audio drivers. Playing media in Kodi I’d noticed that placement is consistently wrong; meaning the incorrect placement remains the same over different media and Amlogic hardwares. This was traced to a failure to get the channel map via snd_pcm_get_chmap() and further analysis showed this failed because the PCM controls are exposed on a different device than the PCM stream. e.g. on LibreTech LePotato with DPCM routing configured for HDMI output, the hw PCM is on the single frontend device 0 but the PCM controls are on device 2: LePotato:~ # aplay -l **** List of PLAYBACK Hardware Devices **** card 0: LIBRETECHCC [LIBRETECH-CC], device 0: fe.dai-link-0 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 LePotato:~ # amixer controls numid=19,iface=MIXER,name='PCM Playback Volume' numid=18,iface=MIXER,name='ACODEC Left DAC Sel' numid=7,iface=MIXER,name='ACODEC Mute Ramp Switch' numid=2,iface=MIXER,name='ACODEC Playback Channel Mode' numid=3,iface=MIXER,name='ACODEC Playback Switch' numid=4,iface=MIXER,name='ACODEC Playback Volume' numid=5,iface=MIXER,name='ACODEC Ramp Rate' numid=17,iface=MIXER,name='ACODEC Right DAC Sel' numid=8,iface=MIXER,name='ACODEC Unmute Ramp Switch' numid=6,iface=MIXER,name='ACODEC Volume Ramp Switch' numid=1,iface=MIXER,name='AIU ACODEC I2S Lane Select' numid=16,iface=MIXER,name='AIU ACODEC OUT EN Switch' numid=15,iface=MIXER,name='AIU ACODEC SRC' numid=14,iface=MIXER,name='AIU HDMI CTRL SRC' numid=13,iface=MIXER,name='AIU SPDIF SRC SEL' numid=12,iface=PCM,name='ELD',device=2 numid=11,iface=PCM,name='IEC958 Playback Default',device=2 numid=10,iface=PCM,name='IEC958 Playback Mask',device=2 numid=9,iface=PCM,name='Playback Channel Map',device=2 https://github.com/torvalds/linux/blob/master/arch/arm64/boot/dts/amlogic/m… or on a Wetek Play 2: WP2:~ # aplay -l **** List of PLAYBACK Hardware Devices **** card 0: WETEKPLAY2 [WETEK-PLAY2], device 0: fe.dai-link-0 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: WETEKPLAY2 [WETEK-PLAY2], device 1: fe.dai-link-1 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 WP2:~ # amixer controls numid=7,iface=MIXER,name='PCM Playback Volume' numid=6,iface=MIXER,name='AIU HDMI CTRL SRC' numid=5,iface=MIXER,name='AIU SPDIF SRC SEL' numid=4,iface=PCM,name='ELD',device=4 numid=3,iface=PCM,name='IEC958 Playback Default',device=4 numid=2,iface=PCM,name='IEC958 Playback Mask',device=4 numid=1,iface=PCM,name='Playback Channel Map',device=4 https://github.com/torvalds/linux/blob/master/arch/arm64/boot/dts/amlogic/m… It looks like the PCM controls of the backend hdmi-codec are not routed through the DPCM driver the same way as PCM streams. We discussed that issue with Jerome, the driver author, but it’s not clear which bits we are missing. i.e. if it's something ASoC DPCM should be handling or if some further plumbing in the card driver or userspace is needed? Any hints into the right direction would be highly appreciated! Christian

[PATCH v3 0/3] kselftest: alsa: Add basic mixer selftest
by Mark Brown 10 Dec '21

10 Dec '21

This series adds a basic selftest for the mixer interface, as discussed in the cover letter for the main patch there's plenty of additional coverage that could be added but this is a good starting point. v3: - Pull in incremental updates adding a fixed library configuration from Jaroslav and support for volatile controls from Takashi Sakamoto. - Stylistic updates suggested by Shuah. v2: - Use pkg-config to get CFLAGS and LDLIBS for alsa-lib. Jaroslav Kysela (1): kselftest: alsa: Use private alsa-lib configuration in mixer test Mark Brown (1): kselftest: alsa: Add simplistic test for ALSA mixer controls kselftest Takashi Sakamoto (1): kselftest: alsa: optimization for SNDRV_CTL_ELEM_ACCESS_VOLATILE MAINTAINERS | 8 + tools/testing/selftests/Makefile | 3 +- tools/testing/selftests/alsa/.gitignore | 1 + tools/testing/selftests/alsa/Makefile | 9 + tools/testing/selftests/alsa/mixer-test.c | 663 ++++++++++++++++++++++ 5 files changed, 683 insertions(+), 1 deletion(-) create mode 100644 tools/testing/selftests/alsa/.gitignore create mode 100644 tools/testing/selftests/alsa/Makefile create mode 100644 tools/testing/selftests/alsa/mixer-test.c base-commit: fa55b7dcdc43c1aa1ba12bca9d2dd4318c2a0dbf -- 2.30.2
