Comment # 5 on bug 1181097 from Takashi Iwai

Thanks.  I couldn't see any changes in HD-audio side, but the difference is
seen in USB-audio (webcam?), which might prevent PA working properly.

The regression of the webcam is tracked in bug 1181014.

Now I'm re-building a new test kernel for bug 1181014, and this might cover
your problem, too.  It's being built in OBS home:tiwai:bsc1181014.  Currently
it contains the old kernel (kernel-default-5.3.18-lp152.1.1.gb5f2dec).  The new
kernel should be something like kernel-default-5.3.18-lp152.2.1.g72e708d.
Please wait until the build finishes and the new package appears, then test the
new kernel.  Note that it's an unofficial kernel, so the secure boot won't
work.
