Hi all!
After installing F17 and graphical login audio works as expected, but when starting a second X-Server, then it's not possible to hear audio. Here are the steps to reproduce the problem:
1. Test audio playback in first X-server
a) aplay someaudiofile.wav
b) aplay -D hw:1,0,0 someaudiofile.wav
result: both command are working fine in the first X-server, means you can hear the expected audio.
2. Start a second X-server
xinit /usr/bin/fvwm -- :1
result: a second X-server show up
(you can also do something like "xinit /usr/bin/xterm -- :1"
3. Try audio playback as in 1.
results:
a) aplay executes and appears to pump out audio somewhere, but there's no audio comming out from the speakers
b) aplay aborts with the followng error:
ALSA lib pcm_hw.c:1401:(_snd_pcm_hw_open) Invalid value for card
aplay: main:696: audio open error: Permission denied
When switching to a text-console (ALT+CTRL+F2), then the aplay examples are working as expected, again.
I guess this has something to do with console permissions. Any feedback is highly appreciated
regards
Bernhard
