Hello,
since a week or two, I have a very strange problem with audio output on a
Windows Vista guest. Right after booting the guest, audio does not work. If I
leave the guest running for some hours (don't know how many, I usually try
again next day), audio output works fine.
I'm using es1370 emulation, but I get the same results with the other
alternatives, too.
Guest: Windows Vista SP1 32bit
Host: Ubuntu 12.10 64bit
% dpkg --list|grep -e kvm -e qemu
ii kvm-ipxe 1.0.0+git-3.55f6c88-0ubuntu5
all PXE ROM's for KVM
ii qemu-common 1.2.0+noroms-0ubuntu2
all qemu common functionality (bios, documentation, etc)
ii qemu-kvm 1.2.0+noroms-0ubuntu2
amd64 Full virtualization on supported hardware
ii qemu-kvm-spice 1.2.0-2012.09-0ubuntu1
amd64 Full virtualization on amd64 hardware
ii qemu-utils 1.2.0+noroms-0ubuntu2
amd64 qemu utilities
Is this a known problem? What could I do to resolve it?
Thanks...
Dirk

Dirk,
sometimes when windows detects new hardware on a write-protected image, it needs to reinstall it on boot.
For USB controllers this is usually on a 10-15 minute cycle. It may use a similar service startup cycle for audio hardware.
Is your Vista image in 'snapshot=off' mode?

I don't think so, but I don't really know. How can I tell?
Bye...

If you are using VirtManager, I don't know, as I'm a command line user, but I guess you could google 'make qemu guest writeable' and that might give you some information about checking.
Sorry I can't help more.

Please open a bug on Launchpad. It will be examined by the Ubuntu
maintainers and possibly forwarded to the QEMU project.
