Title:
  ALSA underruns occurr when using QEMU

Status in QEMU:
  Expired

Bug description:
  I'm running QEMU 1.6.1 on a 64-bit Gentoo Linux system. The guest
  operating system is Windows 7 32-bit. I get multiple identical warning
  messages when using the ac97 or hda sound cards:

  > ALSA lib /var/tmp/portage/media-libs/alsa-lib-1.0.27.2/work/alsa-
  lib-1.0.27.2/src/pcm/pcm.c:7843:(snd_pcm_recover) underrun occurred

  The difference between ac97 and hda is that the former works well,
  while the latter causes the sound to be garbled.

  /var/tmp/portage is the directory where Portage, the Gentoo package
  manager, builds programs. I don't know why it is mentioned in the
  error message.

  I also don't know if this is an ALSA problem or a QEMU problem.

  The command I use is:

  > qemu-system-i386 -cpu host -m 1G -k it -drive
  file=~/QEMU/Windows_7_Privato.qcow2,media=disk,index=0 -vga std -net
  nic -net user -enable-kvm -display sdl -soundhw ac97 -device usb-
  ehci,id=ehci -usb -rtc base=localtime -usbdevice tablet

  My real sound card is an Intel HD Audio:

  > lspci | grep "Audio device"

  > 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD
  Audio Controller (rev 02)

  Please tell me if you need other informations.
