I am still a little bit lost on the way to activate the "export

uncomment that line? 

Thank you very much 

Hi Feadurn,

That was one of my reasons I haven’t migrate all my QEMU script to libvirt. I had issues enabling the host audio like I use in my plain QEMU script. If you’re using Alex’ wrapper script way [1], probably you can regex replace it with ALSA. I never tried myself though.

Reading the description,

# By default, if no graphical front end is configured, libvirt will disable
# QEMU audio output since directly talking to alsa/pulseaudio may not work
# with various security settings. If you know what you're doing, enable
# the setting below and libvirt will passthrough the QEMU_AUDIO_DRV
# environment variable when using nographics.

I think that option is worth to try. Thanks for pointing this.
