Is your audio output device in mythfrontend set correctly? (i.e., to
/dev/dsp or whatever dsp is associated with that card?). If you still
have the config for the first card in your system, the second card is
probably using /dev/dsp1 (/dev/dsp links to /dev/dsp0, I believe),
which you need to tell MythTV to use as its audio out device.
