Ah, then that's exactly the case my latest patch set covers. Either the first patch or the second patch alone should work. https://lore.kernel.org/r/20220926135558.26580-2-tiwai@xxxxxxx https://lore.kernel.org/r/20220926135558.26580-3-tiwai@xxxxxxx Could you verify either of them fixes the problem? thanks, Takashi
