Lost sound in Amarok after update

Need some help diagnosing a sound problem with Amarok. After an update about a week ago, I have no sound in Amarok. All other media apps play sound fine, as well as streaming audio and flash.

I’m using Milestone 6 but this problem was also in M5. I have amarok 2.1.1-4.1, xine backend, and libxine1 from packman. Any help appreciated.

I figured out the problem is with pulseaudio. If I kill pulseaudio, Amarok has sound again.
