Hi,

I'm doing some testing on Ubuntu 12.04 Alpha. All sounds comes out as
static on the Dom0 system. (I can PCI passthrough the audio card to a
DomU and that works). Native sound works fine.

Linux kronos 3.2.0-8-generic-pae #15-Ubuntu SMP Wed Jan 11 15:34:57
UTC 2012 i686 i686 i386 GNU/Linux

Here is the "ubuntu-bug audio" generated report:
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/916985

Let me know if there is any other information that I can provide.

Thanks,
Todd

Did you try 64-bit dom0? What happens if you do not use 'dom0_mem=' arguments?
Does your machine have IOMMU? What is the hypervisor output?

64bit Dom0 works perfectly.

I didn't specify these.

Yes.

Aha! I have an inkling this is the

Could you be so kind and try the 32-bit build with that?

This is "x86: xen: size struct xen_spinlock to always fit in
arch_spinlock_t" from the 3.2 stable tree.

There are many spinlock in sound/ affected by the bug fixed by the above
dunno if any would cause sound distortion but there were plenty of
deadlock opportunities though.

Tried the latest Ubuntu kernel that includes that patch
(http://archive.ubuntu.com/ubuntu/pool/main/l/linux/linux_3.2.0-15.24.diff.gz)
and it still has the same problem.

I think this issue has been fixed right? I believe this:
commit b5031ed1be0aa419250557123633453753181643
Author: Ronny Hegewald <ronny.hegewald@online.de>
Date:   Fri Aug 31 09:57:52 2012 +0000

    xen: Use correct masking in xen_swiotlb_alloc_coherent.
    

fixed it?
