While 5.5.x works fine, mainline as of ac309e7744be (v5.6-rc6+) causes me
some sound-related trouble: after boot, the sound works fine -- but once I
suspend and resume my broadwell-based XPS13, I need to switch to headphone
and back to speaker to hear something. But what I hear isn't music but
garbled output.
I had (see 18d78b64fddc), but not any more in years (and I'd like to keep
using I2S, which has worked flawlessly in these years).
Due to pandemic I'm working remotely and right now won't be able to test
audio quality so focusing on the stream==NULL issue. And thus we got to
help each other out : )
Could you verify issue reproduces on 5.6.0-rc1 on your machine? On my
RVPs looks like it does. There is one more thing that worries me. After
enabling dbg logs I see some IPCs queried but not delivered (dsp busy):

Will be scanning IPCs now. Seems like regression has been introduced
immediately in 5.6.0-rc1 as linux-stable 5.5.7 works just fine for me.
