One thing that does come to mind is that having just recently removed the kernel module from loading at boot on my own system here. Is that it *could* be related to DMA. As it seems the sound modules do include a dma sound module. Which, there has been some issues with DMA on this platform in the past. I only remember seeing issues with dma in relation to SPI, but perhaps it's also an issue for sound too ? Pure speculation on my behalf.
