YM(4)                    BSD Kernel Interfaces Manual                    YM(4)

NAME
     ym -- Yamaha OPL3-SAx audio device

SYNOPSIS
     ym* at isapnp?
     midi* at ym?
     audio* at ym?

DESCRIPTION
     The ym driver provides support for Yamaha OPL3-SAx chipset-based cards.

SEE ALSO
     audio(4), intro(4), isapnp(4), midi(4), wss(4)

HISTORY
     This driver is a thin wrapper around the wss(4) driver.  The ym device
     driver appeared in OpenBSD 2.4.

BUGS
     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.
