Version: (using KDE 4.3.0) OS: Linux Installed from: Ubuntu Packages While playing audio through Amarok, the audio device (default "HDA ATI SB (ALC889A Analog)") stops working, and Phonon falls back to PulseAudio, which does not give any sound output. This only seems to occur at the start of a new track. Restarting Amarok makes it work again.
Which Phonon backend are you using? This could be a duplicate of bug 188444
Closing for lack of feedback. Please refer to bug 188444
