BTW, having the output of alsa-info.sh with a bug report helps
analysis and debugging quite a lot.

So it'd be appreciated if you can ask it always as the first step for
a bug report on Fedora regarding sound.  Especially when it's a
regression, the outputs on both working and non-working cases would be
nice, so that we can compare more precisely.
