Re: [orca-list] Virtualisation software that works well with Orca

[Peter Vágner <pvdeejay gmail com>]

I do have similar script to Mike's and before starting qemu I am setting this variable to force qemu to use pulseaudio for sound.

export QEMU_AUDIO_DRV=pa

And when the guest machine is running I can move its corresponding pulse source-output to whatever sink i.e. if I want to showcase what the VM is playing to my colleagues I will route it to the device with loud speakers connected. For my tinkering I can move it to my bluetooth headset to tinker with.

It works reliably and I am even running Windows 10 this way occassionally.

I am sure qemu can use alsa directly and it hopefully also has some kind of configuration so you can configure its output and input audio device so after digging a bit to the qemu docs you should be able to come up with tweaks for your extensive audio setup.

Greetings

Hi Janina,

Yes, I'm getting sound from within a vm. I mostly use VMs to install/test different versions of SLED and sometimes openSUSE, but I've set up a win10 vm before, and I believe I had NVDA installed there. Here is part of a script that I use to launch it:

if [ x"$1" == "xwin10" ]; then
  qemu-kvm -m 4096 -soundhw hda -usb -netdev user,id=mynet0 -device e1000,netdev=mynet0 -display gtk -hda $1.img
  # if installing, add: -cdrom win10.iso
fi

That being said, I see from another thread that you have a rather complicated sound setup, so I don't know if that would do exactly what you want, but, regardless, it might be worth experimenting with it.

All the complexity with sound on Linux has kept me away from graphical
vms hosted on Linux. I had very few issues with sound on my Mac Airbook
using VMware.

So, I'm very interested to hear Mike propose qemu. I know that's very
reliable for console clients. But, Mike, are you actually getting sound,
including TTS, from qemu guest vms? Can you run NVDA in a Windows guest
on a Linux qemu host, for instance?
