Guest chosen is CentOS 6 with latest updates. oVirt is 3.6.6 on an intel NUC6i5SYH with CentOS 7.2 OS BTW: is it of any importance audio adapter on the host? In case lspci on host gives 00:1f.3 Audio device: Intel Corporation Device 9d70 (rev 21) Client connecting from user portal is Fedora 23 on an Asus laptop U36SD where audio works and lspci gives 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) On CentOS 6 guest the audio adapter detected by OS with lspci is 00:08.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 01) It seems all ok, apart that on guest actually I don't get any audio, also from test speakers page ;-) Both on guest and on client the volume bar is near the maximum. Any hints about debugging? From host point of view the qemu-kvm command line is this one below I don't understand the env variable QEMU_AUDIO_DRV=none ??? If it can be of any importance, I initially configured the guest without sound card and in fact in gnome I saw the audio card as "dummy". Then I powered off the guest and enabled sound card from user portal edit vm (I see it enabled also from admin portal btw...) and then powered on the VM. Now the sound card seems to be present but no audio Sorry for late response:/ This would be best answered by spice guys I guess Latest virt-viewer?
