Hi!
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.
A few dmesg snippets from v5.6-rc6-9-gac309e7744be which might be of
interest. I've highlighted the lines differing from v.5.5.x which might be
of special interest:

(these last two messages already are printed a couple of time after boot, and then
again during a suspend/resume cycle. On v.5.5.y, there are similar messages
"no context buffer need to restore!"). Everything is built-in, no modules
are loaded.
Unfortunately, I cannot bisect this issue easily -- i915 was broken for
quite some time on this system[*], prohibiting boot...
Thanks for taking a look at this issue!

Hi Dominik,
Thanks for reporting, yes, this is Keyon(Yang Jie) here, we do have
several other Broadwell comercial platforms in the market, adding Curtis
from Google in case they may hit similar issue once upgrading to the
latest kernel.
From your description above, it looks the ucm and pulseaudio is
involved, can you help do a quick try if using aplay directly will hit
the same issue?
Thanks,
~Keyon
