ym driver provides support for Yamaha
OPL3-SAx chipset-based cards.
audio(4), intro(4), isapnp(4), midi(4), wss(4)
This driver is a thin wrapper around the
wss(4) driver. The
ym device driver appeared
in OpenBSD 2.4.
The "FM" DAC, wavetable synth, and MIDI port are not supported. I can't seem to access any of the extended registers so master volume, mute, 3-d control might not work through the mixer interface. Lots of work needed.
