Comment # 8 on bug 1140778 from Takashi Iwai

OK, then it's not about the driver loading or the setup.  It was somewhat
misguided.

The problem of test sound playback on YaST isn't new, and this has been always
conflicts with PulseAudio, if you run YaST on the existing desktop.  It works
fine for installer or a dumb desktop without pulseaudio, but once after you
install pulseaudio, it becomes a problem.

YaST may try to play with pasuspender only if pulseaudio is present, but it's
still not 100% correct to assume that pulseaudio takes effect on the target
desktop.

In anyway, it's specific to yast2-sound stuff, how to trigger the playback. 
Reassigned back to YaST team.

If the playback can't work reliably, we may consider dropping the test sound in
yast2-sound setup, too...
