Public bug reported:
Binary package hint: qemu
I am running ubuntu 8.10 x86_64 and using qemu 0.9.1-5ubuntu3. When
running the following command line:
qemu-system-x86_64 -localtime -m 768 -soundhw es1370 -usb -usbdevice
tablet windows-xp.img
qemu unexpectedly begins spitting out errors to the console when the
guest tries to play sound, and no sound can be heard from the guest:

While one might expect OSS support might be broken from the error
messages, sound works in the guest as expected when you specify the
audio driver like so:
QEMU_AUDIO_DRV=oss qemu-system-x86_64 -localtime -m 768 -soundhw es1370
-usb -usbdevice tablet windows-xp.img
Changing QEMU_AUDIO_DRV=oss to QEMU_AUDIO_DRV=alsa also works with no
error messages, although the audio is noticeably worse.
