Hello,
I'm testing video and audio capacity inside a guest.
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
Thanks in advance,
Gianluca

Hi Gianluca,
QEMU_AUDIO_DRV=none is most probably the problem. Libvirt is supposed to set
"QEMU_AUDIO_DRV" to "spice" for VMs with graphics. Please make sure
that the "Optimize for" attribute is set to "Desktop" (in Edit VM
dialog) and try to shutdown and start the VM again. If the QEMU process will still have
QEMU_AUDIO_DRV=none set, you can try to set the variable in /etc/sysconfig/libvirtd by
adding line "QEMU_AUDIO_DRV=spice" and restart the libvirtd service.

Hello,
I'm testing video and audio capacity inside a guest.
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?
Thanks in advance,
Gianluca

Host hw : intel NUC6i5SYH
Client is Fedora 23 with virt-viewer-3.0-1.fc23.x86_64
With a Fedora 24 guest accessed using firefox, user portal and
remote-viewer, sounds are ok (test speakers).
The Fedora 24 guest is configured as "Optimized for Desktop", in its
console options, advanced parameters, I have "soundcard enabled"
And in web admin portal I see this line in f24 VM bottom pane, label "Vm
devices":
https://drive.google.com/file/d/0BwoPbcrMv8mvU0tQZTNBVmZVcTg/view?usp=sha...
Also for a CentOS 7.2 guest, with same config, sound is ok (test speakers)
Instead for a CentOS 6.8 guest with same config I see the device inside the
OS, but no sound:
https://drive.google.com/file/d/0BwoPbcrMv8mvbHRLSDBueVZObTA/view?usp=sha...
In CentOS 6.8 the audio device is seen as:
00:08.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family)
High Definition Audio Controller (rev 01)
and it seems the same in CentOS 7.2 guest OS:
00:08.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family)
High Definition Audio Controller (rev 01)
Under /var/log/libvirt/qemu of host I indeed see
C6 c6desktop.log:

Apparently all is the same in qemu-kvm command lines, comparing c6 with c7
one, but I don't understand who drives instead the QEMU_AUDIO_DRV=XXX in
log file that is different between the two guests (none vs spice) and btw
also in f24 it is spice:

Could it be that initially c6 was created as optimized for server and then
even if changing it to optimized for desktop, it doesn't get actually some
parts of the change?
Or something related to ich6 drivers in CentOS 6?
In messages of C6 guest I see:

Apparently all is the same in qemu-kvm command lines, comparing c6 with c7
one, but I don't understand who drives instead the QEMU_AUDIO_DRV=XXX in
log file that is different between the two guests (none vs spice) and btw
also in f24 it is spice:
[snip]
Understood!
Actually CentOS 6 guest graphics protocol was configured as "SPICE + VNC"
and this was the reason of "QEMU_AUDIO_DRV=none"
Changing it to "SPICE", now I have "QEMU_AUDIO_DRV=spice" in guest
logfile
and also test speakers working inside guest.
Is this expected? I thought that the "+" would have given an aggregate of
functionalities, not a limitation... because initialy I wanted to test both
spice and vnc access...
If this is the case, probably a note or tool-tip could be useful for the
final user because it is not so immediate to correlate video with audio...

Hi,
it is not an expected behavior and filed a bug for that
(https://bugzilla.redhat.com/show_bug.cgi?id=1371243). Please feel free to add any
details.
