thesofproject/sof#4748 only fixes the playback at the beginning, after several seconds playback, sound start to distort again. see #4748 (comment), reopen.
[edit] the issue of sound starts to distort after starting speaker playback several seconds (10+) even existed at the time of enabling 711 + 2x 1316 + 714 codec layout on LNL. let's close this one as it is fixed by thesofproject/sof#4748. I open a new one: #4754
