The program is programming the DMA channel 1 but is trying to use a 16-bit output. I highly suspect your program is misconfigured. In particular please double-check the DMA settings in program's setup and in a BLASTER environment variable. Perhaps you forgot to update your BLASTER var for the newly added SB16 support which is why the SB used to work for you previously (only adding T6 is not sufficient).
