I have two sound card. But I cannot select soundcard for Phonon using systemsetting. This bug has been reported 3 times in other places, but none of them was solved. http://askubuntu.com/questions/115105/phonon-audio-hardware-setup and http://ubuntuforums.org/showthread.php?t=2104043 and http://forum.kde.org/viewtopic.php?f=15&t=98726 Here is how the bug behaves. "But, when I play audio through any program it still uses the speakers and not the headset. So, I went into "Audio Hardware Setup" and saw it's set to use the soundcard. So I changed that to my USB headset, hit apply and closed it. Then I played some music and the same issue. When I opened up the audio hardware setup settings again, it had reverted back to using the soundcard w/ the speakers." Reproducible: Always Actual Results: No change is saved. Expected Results: The change should be saved.
And the Speaker Placement and Testing doesn't work either. But Clementine works fine.
