Sorry, incorrect -- the cs4231 is full duplex. It's only the cs4248 (ad1848) which is not. Need to figure out how to do full duplex on a sound galaxy; old driver didn't do so.
According to a datasheet, the AD1848K (which was a popular version of AD1848) is full-duplex (can work in single-dma mode or with two dma channels).
The AD1848 in my SC-6000 is not the K version (at least it is not marked on the chip) but I saw a photo on the net with SC-6000 and AD1848K (it had no YMF-262 chip but a different one).
I am looking for the AD1848 datasheet for the pre-K version (or list of differences between K and earlier versions).
Also, I would like to know how you put your SG card into full-duplex mode.
It seems that hardware of AD1848/CS4231 was not used to its full potential (SB compatibility was more important).
