applet.audio.yamaha_opl: mark as broken.

whitequark · whitequark · commit 7c7ded1a8bb0 · 2019-04-03T17:55:03.000Z
Looks like the changes in e59730f disturbed a fragile balance between coroutine scheduling and buffering in the hardware. To fix this, the applet likely requires an explicit feedback path between the playback and record coroutines, and/or further rework of pipelining.
