<p class="Pp">The <code class="Nm">opl</code> 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.</p>
<p class="Pp">Access to the device is through the MIDI driver.</p>
<p class="Pp">The <code class="Nm">opl</code> driver usually attaches to a sound
card, but it can also sit directly on the ISA bus.</p>
<p class="Pp">If “flags 1” is specified, the
<code class="Nm">opl</code> driver handles left and right channels of OPL3
swapped. Use this flag if your device has such problem.</p>
