Thanks for the regression report. However, where is your dmesg and/or ALSA =
log
when the regression occurs? What is the playback test file?

FYI, 9f656705c5faa1 ("ALSA: pcm: rewrite snd_pcm_playback_silence()") is
originated as [1/2] of patch series that pokes around the auto-silencer. The
other patch ([2/2]) got NAKed since autofilling buffer should have been don=
e in
alsa-lib (still to be discussed) [1].

Anyway, I'm adding this to regzbot:

#regzbot ^introduced 9f656705c5faa1
#regzbot title Much echoing when playing sound files on Intel Alder Lake PC=
H-P Audio Controller

Thanks.
