I think my problem is the same. Started today after system updates. Running 13.04 and when it boots up to desktop, the first sound I start works. So Rhytmbox, VLC, or Ytube in Chromium, whichever I start first, works, and there is sound. Then when I stop it, next thing I play wont produce the sound and I must reboot to take efect. Rhytmbox wont play songs, VLC and Ytube play video without audio. In Volume control in the panel play/pause ff i bw buttons changed colours to gray from the beggining. It even plays JB, VLC and YT for the first time all three of them work, but if I stop playback and then start anything new, the same problem. Tried to remove 1.0.3 package and reinstall amd64 same package, no results.

The problem seems to be related to multiple audio sources playing/pausing at once. The way I can most reliably reproduce it is playing a song in Rhythmbox while getting Pidgin notification sounds; after pausing the song in Rhythmbox, audio stops functioning completely and pulseaudio must be terminated for it to come back. (Sometimes, even after terminating and restarting pulseaudio, sound still does not work until logout/login or reboot.) I ran pulseaudio with logging enabled and saw that after sound stopped working, this output repeated itself every time I tried to produce a sound: ( 282.746| 3.257) D: [alsa-sink] protocol-native.c: Requesting rewind due to end of underrun. These errors were also frequent after the malfunction: ( 279.489| 0.000) D: [pulseaudio] module-suspend-on-idle.c: Sink alsa_output.pci-0000_00_1b.0.analog-stereo becomes busy. ( 284.375| 0.000) D: [alsa-sink] sink-input.c: Requesting rewind due to corking I've attached my entire pulseaudio log. There's a lot there because I threw a lot of sounds at it to reproduce the error, but hopefully it's helpful.
