--- Comment #3 from Takashi Iwai ---
We need to check how the problem can be reproduced with the raw access without
PA or PW daemon. Namely, try the following:
- Prepare sample WAV files in different formats (16, 24 and 32 bit) and
different sample rates (44100 and 48000Hz). You can try with sox to convert
WAV files, for example.
- For PW, stop the pipewire temporarily via
% systemctl --user stop wireplumber
and run aplay directly for the test WAV file such as
% aplay -Dhw:0,0, -vv foo.wav
where hw:0,0 corresponds to the card#0, device#0. Take a look at
/proc/asound/cards and use the different number if your USB device is assigned
to a different slot.
- Verify the aplay runs with different formats and sample rates, check whether
the problem appears.
- If aplay alone doesn't show the problem, try to run arecord simultaneously
while running aplay, e.g.:
% arecord -vv -Dhw:0,0 -r44100 -c2 -fS16_LE bar.wav
If the above still doesn't show the problem, you'd need to try the different
buffer/period sizes via --buffer-size and --period-size options for
aplay/arecord.
