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

link:
https://it.linuxadictos.com/soluzione- ... -e-pulseaudio-main-c.html

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 ?

https://archive.fosdem.org/2024/events ... BackendInQEMU_Dl33abI.pdf


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.

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

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

Quote:
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.

Quote:
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.

which audio chipset was used for testing

Thanks

on my motherboard i have a :
Realtek S1200A

I also report this article written by @dorindabassey

one of the people who worked on qemu 8.1 with the pipewire audio

https://medium.com/@dorindabassey/pipe ... ckend-in-qemu-be014359475

audio/pwaudio.c: Add Pipewire audio backend for QEMU .

https://gitlab.com/qemu-project/qemu/- ... a0e62d3ecca09837fc23ba4b3


note:
I think maybe a way to go is virt-manager to overcome the GPU obstacle without SUDO
and creating the code for Virt-Manager should not be difficult.

Also because even if I solve the audio
I can not access the GPU.

@white
It does not matter, your problem is not related to host hardware, QEMU or AmigaOS, only your host Linux setup.

@Balaton

mine is only a constructive speech I absolutely do not intend to make criticisms.

@Balaton

this should not be necessary with Ubuntu 25.04 since the iso I download is the same as the one others use.

I follow your advice and I do it willingly.

But I do not do anything special to complicate things
Standard qemu installation compiled to the latest version and everything else without wrong steps is working including the GPU.

Now I did:
systemctl --user stop pipewire.socket pipewire-pulse.socket
systemctl --user disable pipewire.socket pipewire-pulse.socket
systemctl --user mask pipewire.socket pipewire-pulse.socket

sudo apt-get install alsa-base alsa-utils alsamixergui

-----------------------------
Is there anything I can change to make it work in:

/etc/modprobe.d/alsa-base.conf

Thanks.

@Balaton

from what I read the values ​​​​should be 0 instead of 2
this should also apply to USB-AUDIO devices if I wanted to disable the integrated Audio Chipset from the BIOS

But I await your further advice.

@Balaton

Rebooting the system
Now the audio is completely gone there is no active device on Ubuntu 25.04
In the BIOS the audio chipset is still active.
Maybe I'm on the right track if I configure

/etc/modprobe.d/alsa-base.conf

or it's all completely wrong.

white@emulazione:~$

I'm starting to think that pipewire is the right choice, the problem I guess is the audio chipset peripheral on the motherboard

Device 0:

"HDA-Intel" "Nvidia GPU a7 HDMI/DP" "HDA:10de00a7,19da1726,00100100" "0x19da" "0x1726"

Device 1:

"HDA-Intel" "Realtek ALCS1200A" "HDA:10ec0b00,10438797,00100001" "0x1043" "0x8797"

now the device on number 1
with alsamixer ( F6 )
and then sudo alsamixer store
it seems not to keep its settings.

while instead when I open alsamixer it opens device 0 which would be HDMI of the Geforce 4060

what is the pipewire configuration file to edit it by hand and change it to 1


alsamixer -c 1

opens directly
Device 1:
"HDA-Intel" "Realtek ALCS1200A" "HDA:10ec0b00,10438797,00100001" "0x1043" "0x8797"

but then it doesn't keep the settings.

Thanks.

Yet all this is by default in Ubuntu 25.04 there is not much to do.
they put pipewire in it I did not install it

@white
Of course you are free to do what you want and have fun trying random things but if the goal is to fix one particular problem then maybe it helps focusing on that.

For alsa:
$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC887-VD Analog [ALC887-VD Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0

Subdevices: 1/1
Subdevice #0: subdevice #0

Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 8: HDMI 2 [HDMI 2]
Subdevices: 1/1
Subdevice #0: subdevice #0

then I have in /etc/asound.conf

defaults.pcm.!card PCH
defaults.ctl.!card PCH

(which may not be needed but previously I had another card and this makes sure it selects the on board audio). And this gives:

$ aplay -L
...
default:CARD=PCH
HDA Intel PCH, ALC887-VD Analog
Default Audio Device
...
but I don't know how it works on your distro.

For anyone else that is looking to try this with AmigaOne version of AOS4.1Fe, I just saw the Alinea is apparently stocking it again. I was able to order it today. I have the same card that smarkusg used so I hope this will be the magic ticket to full emulation with a real GPU.

@themamboman
If you have any questions, I am happy to help
I described just what @balaton wanted in - > https://www.amigans.net/modules/newbb/ ... id=154815#forumpost154815
In private message I sent you my @

Good luck and have fun with AmithlonNG

Every now and then I disassemble everything to save electricity with two cards and two monitors it consumes more.

A question that I have not found an answer to on google.

But it may be possible that using a Hd .raw previously created for qemu on another machine.
So for convenience I import it again into the new installation of Ubuntu 25.04 to not start all over again for example I do not have full permissions for the HD.raw file
I had this doubt.

Now I don't have the file mounted, I should restore the backup to check the permissions.
A bit like what happens to a real SSD chmod 777 for example.

We put ourselves back in the hands of the blond god, even if in reality everything is less than blond and blue-eyed
If you know a little geography.

it would be awesome if you could provide a linux VM image with QEMU all configured correctly and all one has to do is drop in your own OS4 licensed copy ISO to make it work.

Your alsa is configured to output via pipewire and we've found you can't connect to it as root. Either find out how to allow root to connect to pipewire or change alsa default to a real output on a card you want to use then it should work. No other magic or prayers will fix it.

Who would be the "you" to do that? But then you would be asking questions about how to use the virtual machine image so I'm not sure this would help much.

@Balaton
now I'll try to see what I can find on pipewire and alsa.
Thanks.

For me using root doesn't create any problems at least this has been solved now.
I have access to the GPU

I repeat the question again because it is clear that there are many topics in the forum and I understand that not everything can be read

Someone who is emulating the AmigaONE and uses the
ALCS1200A audio chipset
mounted on their motherboard ?

Just to have a more complete picture.

Thanks.

@NinjaCyborg

There is a very efficient project that is based on Linux that I was a beta-tester for called ( Amilator ) I still have the .iso given to me by the author it relies on FS-UAE to emulate AmigaOS 4.1 Classic.
It works very well. Without needing to install anything if you want.

I have never had any problem exchanging information clearly without it violating the licenses.

Of course I would never put AmigaOS software online because people develop it and work to do it.

But it is also true that a person is free to give away what he wants to whoever he wants if done privately.

Like
Isaac Asimov

A robot may not injure a human being or, through inaction, allow a human being to come to harm.

A robot must obey the orders given to it by human beings, except where such orders would conflict with the First Law.

A robot must protect its own existence, as long as such protection does not conflict with the First or Second Law.

The audio codec chip is not relevant to your problem in any way. You could ask instead if anybody uses QEMU with pipewire.

@Balaton
I know you don't use Ubuntu so I'm excluding you from this comment



If you google pipewire and qemu you will find a lot of users having problems with KVM or Virt-Manager

I haven't been able to find a solution yet and Ubuntu should be easy to find.

Arch Linux also had the exact same problem.

Yes the right question is probably how did you configure pipewire with Ubuntu.

But it should be easy to solve
It would be enough just to have the path to the pipewire configuration file and the Ubuntu configuration file.

I guess this doesn't require a license
for this file.

I would download Ubuntu Studio

If pipewire doesn't work in that distribution it doesn't work anywhere.
Since it's made specifically for those who make music.

Ok I'm downloading it
In the end it's a few minutes.
And it takes a moment to install it and configure it
GPU vfio etc. etc.
