Problem: I'm having problems with the 16-bit DMA Channels.
Cause: The default DMA channel has been changed to an 8-bit channel because a few (not all) motherboards do not have 16-bit DMA channels that operate properly. However, the 16-bit DMA channels may work fine on your computer.
The 8-bit channels are 0-3. The 16-bit channels are 4-7.
Stereo recording will be better on 16-bit channels.Solution: Try to run UltraSound on a 16-bit channel because performance is better. By switching to a 16-bit channel, UltraSound can transfer data twice as fast.
If strange things happen with the 16-bit channel, switch back to a free 8-bit channel.
I have noticed that DOSBox uses 8-bit channels for gus (cause dma is set to 3). Maybe that is the problem?
