QEMU GPU-PCIe AmigaONE

@Balaton
@All

I have the backup so I can make a mistake and start over.
But the suggestion doesn't work at least for me.
Ubuntu 25.04 but like Arch they use ( pipewire )
It's not a problem I do the best I can.

sudo apt install pulseaudio pulseaudio-module-bluetooth gstreamer1.0-pulseaudio
systemctl --user stop pipewire.socket pipewire-pulse.socket
systemctl --user disable pipewire.socket pipewire-pulse.socket
systemctl --user mask pipewire.socket pipewire-pulse.socket
systemctl --user enable pulseaudio.service pulseaudio.socket
systemctl --user start pulseaudio.service pulseaudio.socket

Ok after reboot

sudo -s
pulseaudio -D ( doesn't work )
instead:
pulseaudio --system
it works but there's something wrong I think you need to configure something with pulseaudio.

with SUDO vlc does not start at all not that you can't hear the audio it doesn't start at all

even following this,
However it doesn't work anyway.

I think it would be ideal to create a small tutorial on this audio problem.
Or something that solves this thing.

VFio seems solved
I use Ubuntu 25.04 I also used Arch the problem is always the same.

I have a clean configuration also because I only use it to emulate AmigaOS.
So I don't install strange things.

The question is can't this thing be solved all together.
or whoever did it should explain it to others.

The guide by @falke34 works and is fine.

But I think he hasn't encountered audio problems otherwise he would have written it in the tutorial he wrote.

Apart from this all the steps done with any distribution I have used lead to the same problem with SUDO the audio is not heard.

Someone who explains to everyone the steps to not use SUDO which in the end is the audio that does not work not the real GPU.

Thanks.

note:
One doubt could be the use of two GPUs 4060rtx and R9 280x at the same time.

But from what I read there are other people who use two GPUs on PCIe not integrated.

link pipewire and qemu It can be useful ?

but the basic problem remains how to pass the GPU without using SUDO ?

Stop here and do not start pulseaudio (or stop it if it's running) then add -audio alsa,id=audio0,out.try-poll=off option to QEMU command and see if that works.

Yes do that if you find a solution. We can't write a tutorial on a problem we've never encountered.

Exactly and others who did this either did not have this problem or gave up before even trying sound.

This should not be a problem as GPUs don't influence sound. If it works on the host under normal user and only not under root then it's a problem connecting to the sound server not with hardware. The picture on slide 3 in the presentation you linked shows the setup (just ignore everything within QEMU box where you would have AmigaOS instead of Linux) the QEMU app connects to the sound server on the machine or directly to alsa if using that option. But if the sound server overrides alsa you can't use it and depending on how it accepts connections root may not have the info to connect to it. You could try just uninstalling all pipewire and pulseaudio and just use plain alsa which should work under any user.

I have answered that already and there are guides you can look up (that's where I also found out from) but it's hard to explain if you're missing details.
