QEMU GPU-PCIe AmigaONE

UBUNTU STUDIO

I downloaded 25.04
But also 24.04.2 LTS

For the rest the graphics packages and everything else can always be removed.

I read this maybe it is useful for the purpose:

“Configure Current Audio Configuration” takes you to the screen that allows you to configure the PipeWire Quantum, or (24.04 LTS only) lets you launch Studio Controls if using PulseAudio/JACK*.
24.10 and later only: “Change Kernel Boot Parameters” allows you to change the boot parameters that configure the kernel to be low-latency**.
“START|STOP Dummy Audio Device” Starts or stops the dummy audio device, or allows you to have it start or stop on login.
“DISABLE|ENABLE PipeWire-JACK” allows advanced users to use native JACKd2 via QJackControl.
24.04 Only: “Switch Configuration” installs the classic PulseAudio/JACK configuration and removes the PipeWire Audio configuration, or does the reverse depending on what is installed.*

@balaton

The OP obviously

@white you seem to have completely misunderstood my message

@NinjaCyborg

probably yes, it can happen
If you ask me the question again, I'd be happy to read.

@white
If we can't prove to you that the problem is with your system configuration, isn't it simpler to ask the Linux support forum?
You are currently using Ubuntu. This is a very popular distribution. Many people use QEMU X86_64 with qemu passthru for Windows emulation.
They may even have the same hardware as you and use ‘sudo’
Please ask them for help ... thank you

@smarkusg

Thanks for the advice,
You see a few years ago I needed to reflect.

So I decided to go to Spain and I did the "Camino for Santiago".
It was a particular experience difficult to explain.

Of course there is also in Italy a "The Camino di San Francesco in a city called Assisi"

The purpose is identical, it serves to reflect.

Less famous than the French-Spanish one.
But still important.

For you instead I would always recommend Spain, Pamplona
The Running of the Bulls starts in July.

I think you should go there, get informed maybe you will find your way.

Thanks...

----------------------------------------------
note:
I'm getting a better understanding of how pipewire works,
so I think I'll stick with the current Ubuntu 25.4

This script should help with switching audio but I have yet to try it.
-----------------------------------------------
#!/bin/bash

if [ "$1" == "pipewire" ]; then
echo "Switching to PipeWire..."
systemctl --user stop pulseaudio
systemctl --user disable pulseaudio
systemctl --user enable pipewire
systemctl --user enable wireplumber
systemctl --user start pipewire
systemctl --user start wireplumber
echo "Switched to PipeWire."

elif [ "$1" == "pulseaudio" ]; then
echo "Switching to PulseAudio..."
systemctl --user stop pipewire
systemctl --user stop wireplumber
systemctl --user disable pipewire
systemctl --user disable wireplumber
systemctl --user enable pulseaudio
systemctl --user start pulseaudio
echo "Switched to PulseAudio."

else
echo "Usage: $0 [pipewire|pulseaudio]"
echo "Specify 'pipewire' or 'pulseaudio' to switch between them."
fi

Here I emulated with Virt-Manager KVM with a single GPU with an Ryzen 5800x processor now 5 years ago.
Using a geforce 970.

Amilator a LIVE distribution with FS-UAE with AmigaOS 4.1 in this case I used Kali-Linux

I still have the Amilator iso based on Debian.
The author still maintains his project.
EX Amilator
https://amiga.vk3heg.net/

I wonder if the project could be adapted to qemu once I fix the audio in my setup
With a LIVE stick

Of course it is possible to emulate any AmigaOS system even the classic ones.

Here a nice video I made to understand what it is about for those who do not know the project.

https://youtu.be/tIteEp40txw

I really can't figure out the cause of the audio this only happens with the activation of the RadeonHD.chip driver

as soon as I initialize RadeonHD.chip
here come the errors:
alsa: Could not initialize DAC
alsa: Failed to open `default':
alsa: Reason: The host is not active
alsa: Could not initialize DAC
alsa: Failed to open `default':
alsa: Reason: The host is not active
audio: Could not create a backend for voice `via-ac97.out'

the switch-audio.sh script works fine

#!/bin/bash

if [ "$1" == "pipewire" ]; then
echo "Switching to PipeWire..."
systemctl --user stop pulseaudio
systemctl --user disable pulseaudio

note:

I don't think it's due to the Ubuntu 25.4 installation phase when it asks if you want to choose proprietary drivers or not.

Otherwise, everything I do with Ubuntu works.

I'll try to create some virtual machines with Virt-Manager and see what happens.

Now I had to do the backup and it took me a bit of time.


Aanyway I ordered exactly the card

Asus Radeon R9 270X DirectCU II TOP
2 GB GDDR5 memory

https://www.techpowerup.com/gpu-specs/ ... 70x-directcu-ii-top.b2450

Identical to the one used by other users.
if it doesn't work, patience I'll give up

I'll move on to something else

I also tried this test in the hope that it would work and it worked.
I took my HD.raw file with AmigaONE perfectly working with SiliconMotion the audio is perfectly working.

And I simply took the RadeonHD.chip driver
and renamed it to SiliconMotion.chip

Upon reboot I could select the 32Bit screen with SiliconMotion.
But the audio stopped working.
So it is the RadeonHD.chip driver that conflicts with the audio.

This is my simple report.

I hope it is the graphics card that for some reason creates this problem now I will wait for the:

Asus Radeon R9 270X DirectCU II TOP
2 GB GDDR5 memory

then I will stop I promise

now it's clear that it's a paradoxical situation if I talk about AmigaOS on a Linux forum they probably won't be of much help.
Especially with qemu that emulates AmigaONE.
That's all.

So whoever wants to answer me I'm here and I thank you.
But tell me you're wrong these are the .logs that prove the opposite. Thanks

So I'm simply looking for a solution.
And since we are few to do this experiment what can I say.
Everyone do their own work.
At this point forums are not much use if used in this way.
My respect goes to all those who participate in this forum.

But instead of helping me I only hear you're wrong so I feel bad.
That's all.



also used this script for ALSA:
./alsa-info_alsa-info.sh

which returns this without showing everything because it is too long
the important points:

with:
./switch-audio.sh pipewire

@white
Here's an easy solution. Go to your favourite web search engine. Type: pipewire sound as root. Follow first link (if that does not help then look at further links). I hope that will put an end on your suffering with this. This solution works for most problems

@Balaton

I am trying in every way to make it work but it does not work.
I search on google for possible solutions.
But until now none of these solutions have worked.
When I had to do the GPU Passthrough I thought it was the most difficult thing.

The problem is the audio here is my procedure I start the script and it is also very convenient.

./switch-audio.sh pulseaudio

Result:



systemctl status --user pipewire.service pipewire-pulse.service

Result:
Is this my screenshot correct ?
According to the parameters indicated ?



In addition to asking questions on this topic and seeming that I am not able to do the steps to activate the audio and the various configurations.
I am simply explaining what is happening.

I also understand that if it works for you it is logical that the first thing that comes to mind is that I am doing something wrong.

I would probably do the same too.
But the steps are correct.

note:

The most absurd thing of all is that if I try to use the RadeonHD driver installer even the old ones (2.1) that are then compatible with the Radeon r9 when the system restarts.
It does not install anything in the paths where I should find the drivers.

I will make a video of a few minutes to demonstrate it.
Obviously I am wasting a lot of time on this.
And I did not think I would find these difficulties.

@Balaton

I think that these parameters in:

/etc/modprobe.d/vfio.conf

options vfio-pci ids=1002:6798,1002:aaa0
softdep drm pre: vfio-pci
softdep snd_hda_intel pre: vfio-pci
blacklist radeon
blacklist amdgpu

are not correct for audio

I should probably write something like:

softdep snd_hda_intel (1) pre: vfio-pci
or something similar
but I have no idea what I could write to try another

snd_hda_intel


Why in the .log of !!ALSA Information Script v 0.5.3

it shows me this:

snd_hda_intel (card 0)
snd_hda_intel (card 1)

is it the same audio card one for the jack and the other for the audio ?


If I do:

aplay /usr/share/sounds/alsa/Front_Center.wav

I get:

Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Frequency 48000 Hz, Mono

But I don't hear any sound.


If I use VLC instead all the audio outputs work alsa pulse audio etc.

@white
Quote:Does "sudo vlc ..." work on your system now, or not?
If it still doesn't work you didn't solve anything.

None of your problems is related in any way to the Linux distribution you are using, to QEmu nor to AmigaOS, just about getting the PipeWire sound system working even as root user, instead of simply using ALSA instead as suggested by @balaton, and as @balaton wrote the first Google search result for "pipewire sound as root", in my case (different users will get different results on any major search engine, depending on previous searches, geo-location, etc.) is https://www.reddit.com/r/pipewire/comments/mibuu9/pipewire_as_root/ in which everything is explained in detail you have to do to make it work.
