The OSS driver is using 16kb size buffer. I would bumb it up to 32kb or 64kb also I don't know if they are using auto dma or if your card supports auto dma. I would get a different card like a gus pnp pro or a SB 16 PnP. Also, is anyone else having problems with OSS playing mpeg files at 44khz? On a separate note, does anyone know if the OSS driver is able to play back mpeg files with the same card , Ensoniq Soundscape Elite? Cheers, Amancio >From The Desk Of "David E.
