I've bisected and reverted the following patch fixed the problem.
commit 9f656705c5faa18afb26d922cfc64f9fd103c38d
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 done 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 PCH-P Audio Controller
Thanks.
