I haven't checked your code, but I've found that the poll command only works 
if you open the device in non-blocking mode.

There is an  option to turn on AV_SYNC - I think it's part of the 
/dev/ost/audio device.  I haven't tried it, as I have never had sync problems.

I'll try and do some debugging, but I won't have much time this weekend.
