That's fine, we'd only be delighted to provide some more info.

Our tree is at http://repo.or.cz/w/qemu-kvm/fedora.git

It's based off the stable-0.11 branch

Code is:

        if (played) {
            hw->ts_helper += played;
            audio_capture_mix_and_clear (hw, prev_rpos, played);
        }

If it would help you, I could ask Gene to reproduce with a -O0 build

Built with --audio-drv-list=pa,sdl,alsa,oss

Command line was:

  QEMU_AUDIO_DRV=none qemu-kvm ... -soundhw es1370

Not a lot of info on exactly what the guest is doing with sound, only
that they are Fedora 11 or Fedora 12 guests

Thanks,
Mark.
