Hello,
I'm trying to put Ultrasound on 16 bit DMA but setup test keeps failing :
Pcem detect that it's a 16-bit DMA (here dma channel is 0x5), but I can't go any further.
Is the GUS test accurate for 16 bit DMA or not ?
Thanks.
Problems with 16-Bit DMA ?

AMIDIAG's Sound Blaster 16 tests mostly fail as well, so I suspect there's indeed something wrong with the DMA.

Re: Problems with 16-Bit DMA ?
Two bugs here. Firstly there are some typos in 16-bit DMA handling, probably introduced when adding PS/2 support. These are fixed in rev 768.
Secondly, the GUS code had no real support for 16-bit DMA. This is fixed in rev 769.

Thanks sarah. I tried to dig into your code but i was stuck into this loop thinking that gus supported 16-bit DMA.
