Tool/software:
The audio recording is broken after updating the TI 6.1 Linux kernel from 09.02.00.009 to 09.02.00.010 tag.
The issue was bisected to be related to commit `67d5b2439815 2024-04-29 Jai Luthra dmaengine: ti: k3-udma: Fix teardown for cyclic RX with PDMA`.
The issue can be reproduced using alsa utils and checking the recorded file. In our case this was noticed using alsabat and looping back the audio card in/out.
`alsabat -D hw:"$card",0 -c 2 -f S16_LE -r44100`
alsa-utils version 1.2.6 Entering playback thread (ALSA). Get period size: 2450 buffer size: 22050 Playing generated audio sine wave Entering capture thread (ALSA). Get period size: 2450 buffer size: 22050 Recording ... Playback completed. Capture canceled. BAT analysis: signal has 65536 frames at 44100 Hz, 2 channels, 2 bytes per sample. /tmp/bat.wav.oaN3rJ is not a riff/wave file Return value is -22
Setting rx-num-evt and tx-num-evt to 0 (or removing those properties) from the DT work-around the issue.
