Description Andreas Schwab 2009-08-28 16:26:10 UTC 
Description of problem:
While Amarok is playing no other process is able to open the alsa channel.  This is probably not a problem with Amarok, but with the KDE sound system.

Version-Release number of selected component (if applicable):
phonon-4.3.1-6.fc11.x86_64

Additional info:
$ aplay /usr/share/sounds/alsa/Front_Center.wav
ALSA lib pcm_dmix.c:1008:(snd_pcm_dmix_open) unable to open slave
aplay: main:608: audio open error: Device or resource busy
Comment 1 Rex Dieter 2009-08-28 16:32:00 UTC 
Are you not using pulseaudio?

ie, is kde-settings-pulseaudio installed?

If not, that's the problem, and expectation when pa is not used.
Comment 2 Andreas Schwab 2009-08-28 16:53:18 UTC 
With pulseaudio I get nothing but silence.
Comment 3 Andreas Schwab 2009-08-28 16:57:23 UTC 
I have no problem with two parallel aplay once KDE has let off the device.
Comment 4 Kevin Kofler 2009-08-28 21:21:59 UTC 
You have the default set up to dmix. This doesn't work with Phonon-Xine out of the box. Your options right now (until that bug gets fixed) are to either switch to Phonon-GStreamer or write a small config file to make dmix visible to Phonon-Xine. This is documented in the bug I'm closing this as a duplicate of.
