Comment # 2 on bug 1169471 from Takashi Iwai

This can be the regression in 5.6 kernel.  The problem with the speaker-test is
known, it's partly a bug in speaker-test.  You can avoid it by passing -b
1000000, for example.

Are you testing with Nvidia-binary only, or nouveau?

In anyway, please give alsa-info.sh output.  Run it with --no-upload option and
attach (don't paste) on Bugzilla.
