Ya. pavucontrol what what I launched from within padevchooser last night when I was experimenting. My choices are around 20 different permutations of analog stereo, analog surround, and digital stereo input and output. No choice for digital surround is available. The only options for digital output are stereo or stereo duplex with either analog or digital input. lspci identifies my sound card as "nVidia Corporation MCP55 High Definition Audio," for what it's worth. ALSA plays 5.1 through the s/pdif outputs no problem. Pulse doesn't. Recommendations? Would JACK be worth investigating as an alternative to pulse?
