InhexSTER Posted April 17, 2016 Share Posted April 17, 2016 Hi, I've setup couple VMs and different Linux distros. I have EVGA GTX 960 SC being passed through to guest VM. My GPU works great with passthrough and Nvidia drivers, however GPU HDMI audio stutters and absolutely not playable and even stutters youtube video if used. I first noticed it with sytem sounds when they would stutter and it feels like it repeats and woudn't stop until pulseaudio -k is called. I am using Q35 machine with OVMF bios I tried Arch Linux and Ubuntu both had same issue. However audio seems to be working on SeaBios with Q35. Also when using SeaBios I can see 5.1, 7.1 and Stereo (this is one I use) settings for my sound, but with OVMF it shows only Stereo (2.0) setting. However I would prefer not to use SeaBios as it seems more problematic overall from what I've read about it. I've tried proxmox and Fedora server and it had same issue with audio, but SeaBios wouldn't work with my GPU at all on it I am planning to test this other OS (Mac, Win) maybe I can do some setup from Linux side to fix it, if it is OS issue. Here is XML from Ubuntu with SeaBios with working audio: <domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'> <name>Ubuntu</name>

InhexSTER Posted April 27, 2016 Author Share Posted April 27, 2016 No one had similar issues? I also tried newer version of qemu 2.5.0 on Ubuntu 16.04 Server and I am getting Unable to determine the device handle for GPU error from nvidia-smi on both OVMF and SeaBIOS UnRaid 6.2 Beta has same issue with audio with OVMF Quote Link to comment
monk100 Posted April 28, 2016 Share Posted April 28, 2016 I am having this issue as well. I'm running 3 windows 10 vm's 1-OVMF, i440fx2.5, evga 960ssc 2-OVMF, i440fx2.5, evga 960sc 3-SeaBIOS, i440fx2.5, asus 750ti They all appear to be having this issue. Quote Link to comment
