i cannot get this thing to make any sound, and i don't know what else to
do. i'm running a gateway solo 2500 which uses the opl3sa modules. it
works flawlessly under oss, but to get where i need to go, i've got to
have alsa installed.
i've built it all from source with no problems. i've cranked everything
to full with alsamixer, checked the speaker volume and cables, etc.
nothing.
cat /usr/share/sounds/error.wav > /dev/dsp hangs until i give it a ctl-c.
nothing in any of my log files gives any indication of what the problem
might be.
i don't really know how much information to give (or which information),
so I've included alot below. if i've left out something important, please
let me know and i'll get it right out.
the modules install at boot-up as follows:
# cat /proc/modules | grep snd
snd-pcm-oss 18560 0 (autoclean)
snd-pcm-plugin 15408 0 (autoclean) [snd-pcm-oss]

the available interrupts for opl3sa are 5, 7, 9 and 10. i'm running on
irq 7:

(however, i've tried IRQ 5 and 9 as well -- all with no luck.) /dev/snd

to my untrained eye, everything seems to be correct. but - obviously -
it's not. if anyone has a clue, please let me know.
thanks.
