Hi!
Maybe Windows has srewed up the IRQ/DMA settings of the sound card. What
does "lspnp -v" show? In my case the relevant output is:

0e CSC0000 multimedia controller: audio
        io 0x0530-0x0537
        io 0x0388-0x038b
        io 0x0220-0x0233
        irq 5
        dma 1
        dma 0

0f CSC0010 multimedia controller: audio
        io 0x0538-0x053f

Maybe the two DMA channels have switched?
