[Qemu-discuss] Linux KVM, Windows 7 guest choppy sound

[address@hidden]

Yeah I have the same problem on.
I can hear some sound but quality is very bad.
It seems Windows 7 gets slow especially when it plays sound.

My script is

qemu-system-x86_64 /mnt/win/win7qemu002 -cpu kvm64,+nx -enable-kvm -m 
1536 -soundhw hda -usb

or

qemu-system-x86_64 /mnt/win/win7qemu002 -cpu kvm64,+nx -enable-kvm -m 
1536 -device intel-hda,id=sound0,bus=pci.0,addr=0x7 -device 
hda-duplex,id=sound0-codec0,bus=sound0.0,cad=0 -device 
virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5

but the results are same.

And I try
% export QEMU_AUDIO_DRV=alsa
with or without
% export QEMU_ALSA_ADC=null
% export QEMU_ALSA_DAC=dmix
