The hardware wavetable synth on YMF PCI cards isn't (yet) supported by
ALSA.

snd-mpu401-uart is the driver for the external MIDI port (you'd need a
gameport/MIDI adapter for this). snd-rawmidi is an ALSA module
handling device file management and buffering for MIDI ports.
snd-opl3-lib is the driver for the OPL3 FM synth.

I guess Muse uses the ALSA sequencer. Run "aconnect -o" to see a list
of output ports.

Did you specifiy the parameters for snd-ymfpci in modules.conf?
(e.g. mpu_port=0x330 fm_port=0x388)
