Sound stops working after rhythmbox tried to play sound

Hi,

I'm on Fedora 10 (x86_64). For some days I experience some sound problems:
Rhythmbox does not plays music anymore. Furthermore all other sounds are not
played as well after that.

Step by step:
1. start rhythmbox
2. select a song (ogg) and click play
=> Title bar shows the song's title
=> pulseaudio volumne control shows it too (only the title, no sound data
     shown)
However:
   - No sound
   - no progress in rhythmbox (progress bar stays at the beginning)
   - play button in rhythmbox does not change its symbol to pause
   - besides that, rhythmbox is still responsive, I can switch to other songs
     but still no sound.
3. After that no app (e.g. totem) can play sound (they don't hang, just no
     sound).

If I reboot, I can play sounds using other applications like totem.

If I kill pulseaudio (pulseaudio -k), it will respawn another instance but
that one only finds the NullOutput so no sound as well.

lspci/sound card:
00:10.1 Audio device: nVidia Corporation MCP51 High Definition Audio (rev a2)

In the syslog I can see:
pulseaudio[5082]: module-alsa-sink.c: Error opening PCM device front:0: device
or resource busy.

rhythmbox-0.11.6-19.r6096.fc10.x86_64
wine-pulseaudio-1.1.14-1.fc10.i386


Any suggestions what I can do (besides not using rhythmbox or removing
pulseaudio)?
