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). -- Doug Rabson Mail: dfr@nlsystems.com Nonlinear Systems Ltd.
