I have an Acer Extensa 390 laptop with a Yamaha OPL3-SAx
sound card installed.

I recompiled the Red Hat Linux kernel to use the OPL3
support, but no luck. On bootup, I get a message
about sound configuration starting and ending, but
nothing in between. Cat'ing out /dev/sndstat confirms
that the card hasn't been found.

Has anyone got this card to work? What are the base address
and IRQ settings? Will the Linux PnP system help here?

OPL3 support is just for the fm synth section, use
WSS support, generic opl3, mpu401, dev/audio, and
the default memaddresses, irq's and you should be
good to go

I have essentially the same setup (RH5 and OPL3 soundcard). I too have not
been unable to get it to work. I can tell you how my card is configured, but
I can't for the life of me figure out how to tell the driver to use these
settings. Have you figured it out? Anyway, here is how my card is
configured. Let me know if you have any luck. I would sure like to know how
to tell the sound driver to use these settings.

I/O: E80
IRQ: 10
Play DRQ: 1
Record DRQ: 0

Key point: OPL-3SA is quite a different beast from OPL-3<noSA>.
The former is a complete sound-chip with synth and PCM ("WAVE")
output. The latter is an ancient FM synth device.

(Speaking from memory...)

You need a more up-to-date version of the OSS-Free sound drivers than
that coming with RedHat 5.0 2.0.32 kernel sources if you want to
support the OPL3-SA.
