The
opl driver provides support for the Yamaha OPL2 (YM3812) and OPL3 (YMF262) chips. The chips are FM synthesizers and are capable of producing a wide range of sounds.
Access to the device is through the MIDI driver.
The
opl driver usually attaches to a sound card, but it can also sit directly on the ISA bus.
If “flags 1” is specified, the
opl driver handles left and right channels of OPL3 swapped. Use this flag if your device has such problem.
