Yes, for the sound stuff, something below should make things working.
But it means that we'll lose the SG-buffer allocation and the

We crossed lines there. In general due to better memory compaction and
CMA we have better chances to get larger contiguous allocations these
days, so this might not be too much of an issue in practice.
But turning off the SG DMA scheme seems like a step back. Would be possible to
fix this kind of memory mapping?
