I have an Ensoniq Soundscape S2000 in my machine. I installed OSS last
night and playback seems to work pretty well. I have a lot of problems
with recording though. Even if I select a high data rate, sound recording
is extremely noisy. Also, if I try to record 8 bit samples, it complains
about DMA problems a few times and them completely locks up the system.
The attached program shows this when used to record from the Line-1 input
(CD player).
