Generally right except a little difference.

1.) if i let the swiotlb unchanged at 64 MB and start a DomU with 66 MB or more Ram and do steps 3 and 4 the sound appears; with less RAM there is no sound
2.) if i lower the swiotlb to 32 MB and start a DomU with less then 66 MB Ram and do steps 3 and 4, then the sound is fine.

Attached.

I tried that too but used as parameter dom0_mem=2GB. But i will retry it anyway because i tried many several things so i might have done something wrong in the process.

In that case shouldnt i have that problem on bare metal too? And there is no such problem under a 2.6.31 kernel with the forwardported dom0 patches from gentoo either.

Thanks alot for all the explanations. Now i have a starting-point to do some further investigations.
