I am using KDE 4.10, Kubuntu 13.04. My audio is working great. But when I configure Phonon and try to test the speakers, I don't get any sound.
When I start the configuration tool with:
and press the "Front Left" or "Front Right" button, I get this error message:
ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM 0
Maybe the tool simply fails to load the wav test file? Where are they supposed to be located?
