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:

kcmshell4 kcm_phonon

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?

I had, and fixed, the same problem with my installation. I guess you are using pulseaudio. The solution is to install the libcanberra-pulse package and the tests should work like a charm.

    I am having the same problem, but libcanberra-pulse is already installed. At the moment I suspect that the recent switch to KDE5 broke a few things. – KIAaze Aug 30 '15 at 22:15
  • It seems to be a kcmshell4 vs 5 issue in my case?: https://forum.kde.org/viewtopic.php?f=19&t=128063 – KIAaze Aug 30 '15 at 22:41

    Installing libcanberra-pulse solved it for me also on Arch Linux – Sunday Mar 29 '17 at 17:43
