The fix for this was sent early December:
https://lore.kernel.org/linux-sound/20231207095425.19597-1-peter.ujfalusi@linux.intel.com/

It had the correct Fixes tag but it did not made it to 6.7-rc while
a0575b4add21 did made it.

Mark, Takashi, can you pick the fix for 6.7 (it is in -next)? I think we
might have time for it to land?
