  Hi.
 With kernel 5.7, my system finally switched over to snd_sof_pci for
 the
 intenal card.  I can use mpv and alike via alsa directly, but
 when I try to start JACK I always get the following message:
 ALSA: cannot set period size to 1024 frames for playback
 Adding the verbose flag to JACK doesn't make it any more informativ
 regarding this problem.   With the old hda driver, JACK was perfectly
 working with a buffer size of 1024 (and less). 
 Is the old HDA module still there? maybe blacklist snd_sof_pci? 
There is only one way forward: forward.  I'd rather not do that.  The
old driver had its own problems (no mic).
