[alsa-devel] [PATCH] ASoC: Intel: bytcr_rt5640: Update quirk for Teclast X89
by Hans de Goede 04 Dec '19

04 Dec '19

When the Teclast X89 quirk was added we did not have jack-detection support yet. Note the over-current detection limit is set to 2mA instead of the usual 1.5mA because this tablet tends to give false-positive button-presses when it is set to 1.5mA.

[alsa-devel] [PATCH v4 1/2] ASoC: dt-bindings: fsl_asrc: add compatible string for imx8qm & imx8qxp

[alsa-devel] [PATCH] ASoC: snd-sof-pci - add model parameter and pass it to HDA codec driver
by Jaroslav Kysela 03 Dec '19

It may be useful to pass the specific model to the generic HDA codec routines like the legacy HDA driver (snd-hda-intel) allows. The model name "sofbus" is tricky anyway.

[alsa-devel] Integrating Texes Instruments PCM1860 ADC
by Umar Dockrat 03 Dec '19

03 Dec '19

Good Day, I have been struggling with the integration of a PCM1860 ADC for audio recording. I have created a "sound card" board that contains both a PCM5102A (DAC) and PCM1860 (ADC). The main processor is an Omega Onion 2 which is based on MediaTek MT7688 SoC device. I am struggling with creating the device tree as the Kernel currently has reference to the PCM186X where X is 2,3,4 or 5 but not the more simple PCM1860. The difference between the PCM1860 and the PCM186X is that the PCM1860 does not have I2C control and is HW configured using pull up/down. https://www.kernel.org/doc/Documentation/devicetree/bindings/sound/pcm186x.… I have tried multiple device tree setup's and have only got the DAC working when configured in isolation, as soon as I add any reference to the ADC then both DAC and ADC are not recognised. This DTSI allows the DAC to function https://pastebin.com/z9H67DHd There are my attempts at including the DAC and ADC: https://pastebin.com/RLsKNsiR https://pastebin.com/rmJVcCz1 Please can someone assist with the correct way to integrate this ADC device? Any suggestions on how to properly debug this further is also really appreciated. Thanks, UFD

[alsa-devel] a52 plugin + ffmpeg with libswresample
by Giovanni Harting 03 Dec '19

03 Dec '19

Hello, I'm working on restoring functionality to the a52 plugin. ALSA build with ffmpeg without (deprecated) libavresample does not build this plugin, since libavresample is missing. Archlinux for example does not build with libavresample anymore [1], therefore a52 is missing in alsa-plugins builds since that change happened. I ported rate-lav to libswresample, which seems to work well after a month of daily use. The oddity is that a config file (asoundrc, [2]), that worked fine with alsa-lib 1.1.6, does not work with 1.1.7+. I could not find a change that causes this. I traced it down to _snd_pcm_rate_open() in pcm/pcm_rate.c, where keywords from within pcm {} are passed into, where it fails with "Unknown field card" (for example). I worked around it by filtering out all keywords [3], but that feels a little unclean. Is there a proper way to fix this? I'm not familiar with ALSA's config parsing. I'll submit patches for both once I figured out how to fix this. [1] https://bugs.archlinux.org/task/60586 [2] pcm.a52 { @args [CARD] @args.CARD { type string } type rate slave { pcm { type a52 bitrate 640 channels 6 card $CARD } rate 48000 format S16_LE } } [3] if (strcmp(id, "bitrate") == 0 || strcmp(id, "rate") == 0 || strcmp(id, "card") == 0 || strcmp(id, "channels") == 0 || strcmp(id, "format") == 0) { continue; }

[alsa-devel] [PATCH alsa-lib] ucm: Do not fail to parse configs on cards with an empty CardComponents lists
by Hans de Goede 03 Dec '19

03 Dec '19

Since the UCM profiles for all Bay- and Cherry-Trail SST cards have been moved over to UCM2, parsing them fails with: ALSA lib ucm_subs.c:220:(uc_mgr_get_substituted_value) variable '${CardComponents}' is not defined in this context! This completely breaks audio support on all Bay- and Cherry-Trail devices. This is caused by these non-SOF ASoC using cards having an empty CardComponents list. Which in itself is fine, but is rejected by the ucm_subs.c code. This commit changes the ucm_subs code to accept an empty string as a valid value for CardComponents restoring audio functionality on these boards.

[alsa-devel] [PATCH 0/3] Add NAU8812 support
by Marco Felsch 03 Dec '19

03 Dec '19

Hi, this small series adds the documentation and support for the nau8812 devices. The exisiting nau8810 driver can handle both devices so we only need to add the dt-bindings and inform the user by adapting the Kconfig entry. Futhermore the series adds the support for the aux-port control. @John Hsu Please can you verify that register accesses to the aux-port control bits don't affect the nau8810 devices? I don't have such a device but the documentations says that those register fields are just '0'ed. So I assume the nau8810 devices ignore such writes.
