With luck this is the same as 684149. If not this will go pretty much to the bottom of the priority list as sound without spice is not supported. which app you are using to record sound with the rhel6 guest? Found it, gnome-media-apps carries the sound recorder app. How does the host-side audio configuration look like? Do you use alsa? Or pulseaudio? See "qemu -audio-help" for more info on audio setup. Hi Gerd i am trying to reproduce it with alsa and pulseaudio. i will update testing result to bz next monday.

The pulseaudio driver is named "pa" btw. Hi Gerd, I am back, see this is here a long time, i tried with the latest qemu-kvm: qemu-kvm-0.12.1.2-2.172.el6.x86_64 2.6.32-171.el6.x86_64 when i export QEMU_AUDIO_DRV=pa, i can reproduce it, when i use alsa, it keeps prompting "alsa: Unexpected state 1", guest acts slowly, especially when i use Sound Reorder. Sound with vnc is unsupported, lowering priority. |
