I'm happy to report back that all the changes required to address this are
now merged upstream and queued for 5.11 kernel. This affects all SOF ALSA
drivers (Intel and non-Intel) and with the fix in, JACK works with all the
common 2^n period size settings. Do note SOF FW's default scheduler is
timer tick based and has a 1ms tick interval, so this might not be ideal
for all JACK usages (see commit messages for details).

[1/2] ASoC: SOF: relax PCM period and buffer size constraints

[2/2] ASoC: SOF: Intel: add hw specific PCM constraints

Br, Kai
I don't think the constraint makes really
sense, but that's what it is
now (for all systems where 192 is the minimum period size). Luckily
Thanks a lot for chiming in and shedding some light on this issue.
Also thanks for volunteering to get it fixed.
I am looking forward to that fix landing on my system.
