I'm having a weird issue with audio. In mythtv and xbmc for linux, sound works great over my nvidia hdmi. However, when I go to play anything from within mythbuntu---say grooveshark on firefox, I get no sound.......
mythbuntu recognizes my audio, below is the output:
00:08.0 Audio device: nVidia Corporation MCP79 High Definition Audio (rev b1)

Any Ideas?
