Focusrite Scarlett 8i6 silent input stream
by ZTube 30 Mar '22

30 Mar '22

I'm trying to get my Focusrite Scarlett 8i6 to run with alsa, however while the sound output to the device works fine, the input does not and merely delivers a silent stream. Since I can't find any reason for the input stream to be completely silent I suspect this might be a driver bug. $ arecord -D hw:0,0 -f S32_LE -r 48000 -c 10 | aplay just results in complete silence I'd be happy to provide more logs/detail if needed. Any idea what might be going on? Thanks, ZTube [alsa-info.sh] https://paste.debian.net/1236037/

[PATCH] ALSA: hda: Avoid unsol event during RPM suspending
by Mohan Kumar 30 Mar '22

30 Mar '22

There is a corner case with unsol event handling during codec runtime suspending state. When the codec runtime suspend call initiated, the codec->in_pm atomic variable would be 0, currently the codec runtime suspend function calls snd_hdac_enter_pm() which will just increments the codec->in_pm atomic variable. Consider unsol event happened just after this step and before snd_hdac_leave_pm() in the codec runtime suspend function. The snd_hdac_power_up_pm() in the unsol event flow in hdmi_present_sense_via_verbs() function would just increment the codec->in_pm atomic variable without calling pm_runtime_get_sync function. As codec runtime suspend flow is already in progress and in parallel unsol event is also accessing the codec verbs, as soon as codec suspend flow completes and clocks are switched off before completing the unsol event handling as both functions doesn't wait for each other. This will result in below errors [ 589.428020] tegra-hda 3510000.hda: azx_get_response timeout, switching to polling mode: last cmd=0x505f2f57 [ 589.428344] tegra-hda 3510000.hda: spurious response 0x80000074:0x5, last cmd=0x505f2f57 [ 589.428547] tegra-hda 3510000.hda: spurious response 0x80000065:0x5, last cmd=0x505f2f57 To avoid this, the unsol event flow should not perform any codec verb related operations during RPM_SUSPENDING state.

[PATCH v2] ALSA: hda/realtek: Fix audio regression on Mi Notebook Pro 2020
by Kai-Heng Feng 30 Mar '22

30 Mar '22

Commit 5aec98913095 ("ALSA: hda/realtek - ALC236 headset MIC recording issue") is to solve recording issue met on AL236, by matching codec variant ALC269_TYPE_ALC257 and ALC269_TYPE_ALC256. This match can be too broad and Mi Notebook Pro 2020 is broken by the patch. Instead, use codec ID to be narrow down the scope, in order to make ALC256 unaffected.

Fix support for sof-essx8336
by GitHub pull_request - opened 30 Mar '22

30 Mar '22

alsa-project/alsa-ucm-conf pull request #144 was opened from mchehab: There are a couple of issues at the support for sof-essx8336, causing it to fail working. This PR fix them. Tested on Huawei Matebook D15. Before the fix, the device was appearing as "sysdefault:0" instead of "hw:0", and there were several other problems. After the fix: - the device is now identified as hw:0; - calling alsamixer without `-Dsysdefault:0` (or `-Dhw:0`) now shows a mixer (instead of showing nothing); - The HDMI volume controls now appear; - Using `alsaucm load` now works fine. There are still a couple of things to be fixed, but I suspect that at least some of them would require firmware (or driver?) changes: - the internal microphone is not working yet; - the headphone/headset doesn't work.

[PATCH 0/6] ASRC support on Tegra186 and later
by Sameer Pujar 29 Mar '22

29 Mar '22

This series adds support for Asynchronous Sample Rate Converter (ASRC) module on Tegra186 and later generations of SoCs. ASRC is a client of AHUB. The driver and DT support is added to make it work with Tegra audio graph card. The module can be plugged into audio path using ALSA mixer controls. ASRC supports two modes of operation, where it gets the ratio info from SW and ratio detector module. Presently the support is added for SW mode.
