how to debug no audio in guest?
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 2016-06-11 09:22:13.698+0000: starting up libvirt version: 1.2.17, package: 13.el7_2.4 (CentOS BuildSystem <http://bugs.centos.org>, 2016-03- 31-16:56:26, worker1.bsys.centos.org), qemu version: 2.3.0 (qemu-kvm-ev-2.3.0-31.el7_2.10.1) LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin QEMU_AUDIO_DRV=none /usr/libexec/qemu-kvm -name c6desktop -S -machine pc-i440 fx-rhel7.2.0,accel=kvm,usb=off -cpu Broadwell-noTSX -m size=3145728k,slots=16,maxmem=4294967296k -realtime mlock=off -smp 1,maxcpus=16,socket s=16,cores=1,threads=1 -numa node,nodeid=0,cpus=0,mem=3072 -uuid 68a82ada-a1d2-44d0-85b0-f3a08cc2f579 -smbios type=1,manufacturer=oVirt,produ ct=oVirt Node,version=7-2.1511.el7.centos.2.10,serial=AC1EDDD3-CAF1-2711-EE16-B8AEED7F1711,uuid=68a82ada-a1d2-44d0-85b0-f3a08cc2f579 -no-user -config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/domain-c6desktop/monitor.sock,server,nowait -mon chardev=charmo nitor,id=monitor,mode=control -rtc base=2016-06-11T09:22:13,driftfix=slew -global kvm-pit.lost_tick_policy=discard -no-hpet -no-shutdown -boo t menu=on,strict=on -device ich9-usb-ehci1,id=usb,bus=pci.0,addr=0x9.0x7 -device ich9-usb-uhci3,masterbus=usb.0,firstport=4,bus=pci.0,addr=0x 9.0x2 -device ich9-usb-uhci2,masterbus=usb.0,firstport=2,bus=pci.0,addr=0x9.0x1 -device ich9-usb-uhci1,masterbus=usb.0,firstport=0,bus=pci.0, multifunction=on,addr=0x9 -device virtio-scsi-pci,id=scsi0,bus=pci.0,addr=0x3 -device virtio-serial-pci,id=virtio-serial0,max_ports=16,bus=pc i.0,addr=0x4 -drive if=none,id=drive-ide0-1-0,readonly=on,format=raw -device ide-cd,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -drive file=/rhev/data-center/00000001-0001-0001-0001-000000000343/572eabe7-15d0-42c2-8fa9-0bd773e22e2e/images/aff55e62-6a41-4f75-bbd3-78561eae18f3/ f520473e-8fbe-4886-bb64-921b42edf499,if=none,id=drive-virtio-disk0,format=raw,serial=aff55e62-6a41-4f75-bbd3-78561eae18f3,cache=none,werror=s top,rerror=stop,aio=threads -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x5,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -netdev t ap,fd=28,id=hostnet0,vhost=on,vhostfd=29 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=00:1a:4a:16:01:51,bus=pci.0,addr=0x7 -chardev soc ket,id=charserial0,path=/var/run/ovirt-vmconsole-console/68a82ada-a1d2-44d0-85b0-f3a08cc2f579.soc k,server,nowait -device isa-serial,chardev=charserial0,id=serial0 -chardev socket,id=charchannel0,path=/var/lib/libvirt/qemu/channels/68a82ada-a1d2-44d0-85b0-f3a08cc2f579.com.redhat.rhevm.vdsm,server,nowait -device virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=com.redhat.rhevm.vdsm -chardev socket,id=charchannel1,path=/var/lib/libvirt/qemu/channels/68a82ada-a1d2-44d0-85b0-f3a08cc2f579.org.qemu.guest_agent.0,server,nowait -device virtserialport,bus=virtio-serial0.0,nr=2,chardev=charchannel1,id=channel1,name=org.qemu.guest_agent.0 -chardev spicevmc,id=charchannel2,name=vdagent -device virtserialport,bus=virtio-serial0.0,nr=3,chardev=charchannel2,id=channel2,name=com.redhat.spice.0 -spice port=5901,tls-port=5902,addr=0,x509-dir=/etc/pki/vdsm/libvirt-spice,seamless-migration=on -vnc 0:3,password -device qxl-vga,id=video0,ram_size=67108864,vram_size=8388608,vgamem_mb=16,bus=pci.0,addr=0x2 -device intel-hda,id=sound0,bus=pci.0,addr=0x8 -device hda-duplex,id=sound0-codec0,bus=sound0.0,cad=0 -chardev spicevmc,id=charredir0,name=usbredir -device usb-redir,chardev=charredir0,id=redir0 -chardev spicevmc,id=charredir1,name=usbredir -device usb-redir,chardev=charredir1,id=redir1 -chardev spicevmc,id=charredir2,name=usbredir -device usb-redir,chardev=charredir2,id=redir2 -chardev spicevmc,id=charredir3,name=usbredir -device usb-redir,chardev=charredir3,id=redir3 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x6 -msg timestamp=on 2016-06-11T09:22:13.748410Z qemu-kvm: warning: CPU(s) not present in any NUMA nodes: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 2016-06-11T09:22:13.748524Z qemu-kvm: warning: All CPU(s) up to maxcpus should be described in NUMA config main_channel_link: add main channel client main_channel_handle_parsed: net test: latency 21.910000 ms, bitrate 51635025 bps (49.242997 Mbps) inputs_connect: inputs channel client create red_dispatcher_set_cursor_peer: main_channel_handle_parsed: agent start main_channel_handle_parsed: agent start

Now the sound card seems to be present but no audio

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.

[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... Gianluca
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. Jakub ----- Original Message -----
