Hi,
Here is a patch that fix a problem with the opl3sa2 driver. The problem
is that if you use two distinct DMA channels, then you can play but
can't record OR record and can't play, you get the message "DMA timeout
(...)"
The dma and dma2 are not initialized with the real DMA channels and they
remain at -1.
