Simultaneous audio capture from branched capture pipelines fail

[singalsu]

To replicate the issue need for SOF the topologies built from thesofproject/sof#9146

The used kernel is topic/sof-dev 550791b build from today.

The platform is UPX-i11, the default topology sof-hda-generic-4ch.tplg is replaced with sof-hda-efx-generic-4ch.tplg. If I run these commands sequentially both DMIC captures work. First capture PCM is 4ch, the second 2ch, while DMIC is 4ch. The channels count conversion is done in TDFB beamformer.

arecord -Dhw:0,6 -f S32_LE -c 4 -r 48000 -d 10 rec1.wav
arecord -Dhw:0,200 -f S32_LE -c 2 -r 48000 -d 10 rec2.wav

If I start first capture of rec1.wav, and then launch from other window capture of rec2.wav. I get to latter this error:

singalsu@ekstremisti:~$ arecord -Dhw:0,200 -f S32_LE -c 2 -r 48000 -d 10 rec2.wav

The issue can be also replicated with HDA analog capture with topology sof-hda-efx-generic.tplg applied instead of default sof-hda-generic.tplg in non-DMIC systems. In this case both capture PCMs are 2ch. The commands to use are

arecord -Dhw:0,0 -f S32_LE -c 2 -r 48000 -d 10 rec1.wav
arecord -Dhw:0,201 -f S32_LE -c 2 -r 48000 -d 10 rec2.wav

Both work if run sequentially but not when launched with overlap, e.g. rec1.wav first, then rec2.wav, where the latter fails.

@ujfalusi @kv2019i Here's the issue we discussed this week. This is no more blocking me since I chose to use pipelines without branches, algorithms for multi-purpose endpoint are set to bypass to be set up for processing by ALSA UCM.
