Hi! I just bought a SB16 card and have installed it under OS/2 Beta II and DOS/Windows. It appears my motherboard does not support the card through High DMA channels 5+, but according to the SB16 docs you can just use the low dma channel for 16 bit sound. Anyway, under DOS and Windows this works fine and I can play 16 bit sounds as well as 8 bit sounds. Under OS/2 I can only play 8 bit sounds. If I have the high DMA channel set to the same channel as the low DMA (or any other low <5 channel), when I play a 16 bit sound I either get very scratchy sound followed by OS/2 crawling (even though the swapper has not grown to enormous size) - so I have to reboot, OR OS/2 just reboots by itself. Has anyone encountered this problem? Can anyone make any suggestions? As I said, it works fine under DOS/Windows and works for 8-bit under OS/2. Some details: The Sound driver is SB16 driver version 2.34 My settings are: Card: 1 DMA (8-bit): 1 DMA (16-bit): 1 IRQ: 5 I/O: 220 MPU: 330 Buffer size: 8 the device lines are: DEVICE=D:\mmos2\sb16d2.sys 1 1 1 5 220 8 /N:SBAud1$ DEVICE=D:\mmos2\AUDIOVDD.SYS SBAud1$ I have tried using DMA (16-bit) = 5 etc (ie higher channels). In this case I get no sound on 16 bit samples....but OS/2 does not reboot itself or crawl. Does this mean I can't use 16-bit sound under OS/2? PLEASE HELP! Any ideas/assistance appreciated. Jamie
