I already have the patch available to have quake run
but this implies full duplex processes must read before
writing if they want to use the device in full duplex mode.

I tried contacting Alan to see if he thought this was
feasible but haven't had news from him yet.

Actual policy is

16 bit required: 16 bit recording and 8 bit playback
8 bit required: 8 bit recording and 16 bit playback

Expected policy is:
Work as before. If full duplex is required and read
occurs before write remain full duplex, otherwise
switch to semi-duplex behaviour.

I have tried it with quake and works.

Cheers
