The criterion for skipping the tests should be "no audio", not
"running under qemu" - otherwise they will still fail on real hardware
that lacks audio devices.

I think mixerctl should be fixed, at least for the case where there
are no arguments. I don't have an opinion on the "mixerctl -d
Looks like the problem doesn't occur on amd64 because it has
"pseudo-device pad" in GENERIC. I wonder why i386 doesn't.
