OSS: drop ADC buf

I have the same behaviour, but without the ADCbuffOSS business. I've tried both FreeOSS and commercial OSS. From what I can tell the only /dev/dsp channels that are open on my machine are /dev/dsp0:/dev/dsp1:/dev/dsp:/dev/audio

some of which may be aliases I don't really know. What I have been able to determine is that /dev/dsp2 is not available for input or output. I'm going to have a look in the code and see if I can find out why it is looking to
/dev/dsp2. Perhaps the most recent OSS changed it's behaviour and is not sending pd the correct info.
