[ Upstream commit 4c267ae2ef349639b4d9ebf00dd28586a82fdbe6 ]
When the DMA mode is changed on the (still real!) SB AWE32 after
playing a stream and closing, the previous DMA setup was still
silently kept, and it can confuse the hardware, resulting in the
unexpected noises. As a workaround, enforce the disablement of DMA
setups when the DMA setup is changed by the kcontrol.
