I found that. The reason is they must put in /home/user directory, if not, they will not works as they are in the directory which is group of root, not group of user.
Now it works.
Sorry, maybe I’ve annoyed you, I should consider learning Linux seriously…
Just use toggle function to mute/unmute:
amixer sset Master toggle
Thanks! You are right. Sorry for my ignorance.
Thanks! We missed that!
This thread has been incredibly helpful. I have successfully created a disposable sys-audio qube that works on my Librem 14.
However, in order for it to work, I need to make it startup, then shutdown, then startup, then shutdown, and then startup a third time. Otherwise, it does not recognize the audio device as being attached. And this only seems to work once per session. If, after doing this triple-startup and having a working sys-audio, I decide to shutdown sys-audio, then I will not be able to get sys-audio to startup again with audio device recognized until I reboot QubesOS itself.
When creating a non-disposable sys-audio qube, there appears to be an unpredictable number of startups and shutdowns needed before it recognizes the audio device as being attached. So the predictability of the disposable makes it the better option for a stable solution here on my Librem 14.
I am very curious why this procedure of startups and shutdowns is necessary at all. Is anyone familiar with this? Is there anyone else with a Librem 14 that has created a sys-audio qube?
Here are all of the steps that I followed for making a disposable sys-audio qube:

A few notes:
You can create one sys-audio without using the officially provided script.
In the guide, replace
Then, create sys-audio based on deb11-min-audio.
with
create appvm “sys-audio”, set its virtualization mode to “HVM”, disable memory balancing, attach appropriate “Devices” to it (those whose names start with “Audio”, etc), configure them with ‘no-strict-reset’ (at the bottom of the “Devices” page)
If you manually create sys-audio, and found that in sys-audio, pavucontrol cannot see your soundcard, but “sudo alsamixer” can, then you need to “sudo adduser user audio” in its template VM.
This thread was really helpful for me to set up an audio qube. I followed some of its steps since I reinstalled QubesOS when R4.1 was realeased and lost the setup described here.
The difference is that I wanted to use Bluetooth and had sys-usb handling it. So in my case I decided to make sys-usb
my audiovm
– there may be some vulnerabilities associated with that but I was too lazy for searching how I could attach the Bluetooth device with sys-audio
, as it was not appearing in the USB drop-down menu. So in the above steps, instead of creating a new VM, all I had done was to perform the steps in the sys-usb
VM. Bluetooth headset is working properly and also the keyboard shortcuts described above.
One more hint, I was missing a systray icon from which I could control volume. As I don’t know how to place the xfce4-pulseaudio-plugin
for the sys-audio
(sys-usb
in my case) in the main xfce panel (which runs in dom0), my partial solution was to add a launcher widget to the panel and set its command to qvm-run --pass-io sys-usb "pavucontrol"
. So now I don’t need to open a terminal in sys-audio
and type pavucontrol to open the mixer. There might be a better solution to this, but that’s what I have for now.
PS: I actually took some additional steps to install the required packages to run audio and usb services in a fedora-36-minimal fresh template. From this template I made a disposable template in which the modprobe file was added. The autostart scripts were placed in sys-usb
.
My bluetooth device is in the devices widget drop-down menu. It has no name, only a XXXX-XXXX serial number.
@whoareyou, I’ve been trying to create a sys-audio by following this thread, specially @dom0 post. I have gotten most of the “milestones”, i.e. appVMs showing on Playback and Built-in Audio Analog Stereo showing on Output Devices.
Problem is, much like it was for you, my videos hang at 0:00. I tried the sudo alsactl init
command on sys-audio and got the exact same error as you did. Would you mind explaining where I should create the snd.conf
file and what should the contents be?
The snd.conf
file should be created in the TemplateVM (deb11-min-audio) and placed in the /etc/modprobe.d/
directory. The contents should be this:
options snd_hda_intel power_save=0
This is the command that I used to create the file in deb11-min-audio TemplateVM:
touch /etc/modprobe.d/snd.conf && echo -e "options snd_hda_intel power_save=0" > /etc/modprobe.d/snd.conf
I have recently noticed that I cannot attach my built-in microphone using my debian-minimal-based sys-audio setup. I experience the same error message described in this post whenever I try to attach the microphone to any AppVM:
Error Attaching device Microphone to AppVM failed. Error: QubesVMError - Failed to attach audio input from dom0 to AppVM: pulseaudio agent is not running.
I think that I forgot to test the microphone after setting up this disposable sys-audio, since I do not use the microphone often, and so I think that there must be some extra step.
Is there anyone that can be of assistance here? Anyone with a Librem 14 setting up a similar sys-audio?
It’s better to open separate topic for the issue. With a better visibility it would better help future readers.
@dom0, it seems I had followed your tutorial quite closely and I already had that file.
I’ve spent some time googling the issue and ended up finding this thread which gave me the answer I needed. Which was to add an extra command to the sys-audio-start script you have in your tutorial. The extra command was qvm-run --pass-io sys-audio “amixer -c0 set ‘Auto-Mute Mode’,0 Disable”
.
Regarding the microphone, I tried testing it and had the same issue as you did. Would be good if someone more knowledgeable could shed some light on what could be the cause.
But it seems that, since I have a Librem 14, which has the bluetooth provided by the wireless network card, I will have to redo all of this in my Fedora sys-net, as the reason I went through the trouble of creating a sys-audio was because I want to be able to use a bluetooth headset without compromising dom0.
Would there be any difference in the packages I need to install given that the template will change form Debian to Fedora? My understanding is that sometimes packages have slightly different names in different Linux distributions.
I made a new post here and received a response with the solution:
Someone can correct me if I am wrong on any of this, but here is my thinking of Bluetooth and the Librem 14:
If you want to use the built-in Wifi-Bluetooth module for Bluetooth audio in a sys-audio qube, then you will have to have the device attached to the sys-audio qube. There are a few options here:
attach built-in Wifi-Bluetooth to sys-net and use as sys-audio too (one sys-* qube used for both sys-net and sys-audio functions)
attach built-in Wifi-Bluetooth to sys-net and use USB Bluetooth device for sys-audio
attach built-in Wifi-Bluetooth to sys-audio and use USB Wifi device for sys-net
One thing to consider is that the built-in Wifi-Bluetooth module does not need any drivers installed in order to use the Wifi, but you would need to install a non-free driver in order to use the Bluetooth.
I made a few attempts to get the built-in Bluetooth to work, but I decided to wait and see if anyone else ends up making a good write-up. Bluetooth is not very important to me, but I would be interested in understanding how to use it if the need ever does arise.
Also, I have split my Wifi and Ethernet networking devices into two separate service qubes: sys-net and sys-wifi. You may want to consider whether you want/need your Wifi and Ethernet in the same service qube.
I almost forgot to mention that I use debian-minimal templates for all my service qubes, and you could as well. There is no need for Fedora if you do not want to use it. That is one of the best things about QubesOS: Choice.
@dom0, thank you for the info on the mic. I managed to get it working on my comms qube.
The second option you wrote about peaked my interest. I believe in that case I would have to install the Bluetooth binary blob on sys-net, as it is the qube with the “hardware” attached to, and once the USB Bluetooth becames available on Qubes Device manager attach it to sys-audio. Unfortunately, it will be a couple of weeks before I’ll have time to tinker around with that, but I have it on my ToDo list now.
I understand that using non-free binary blob is not a good idea but I’ve become quite attached to my headset. I use it pretty much all the time, as the noise canceling is surprisingly good, making the sound crystal clear. (as you can see I’ve really grown attached to it )
I have thought about splitting my WiFi and Ethernet devices, but I plan on adding a sys-vpn qube and in that case I would have to either make 2 of them and connect one to each networking qube or keep switching the networking qube on sys-vpn. Neither option really appeal to me, but I have been thinking about it as I need at least one qube connected in the open (netflix…).
If you don’t mind me asking, why do you pick debian-minimal for your service qubes instead of fedora-minimal? My choice, if it can be called that, was essentially laziness as I left it on the default one.
There are a few reasons why I prefer Debian-minimal templates:
Debian has fewer updates than Fedora, and so I do not need to change my templates as often.
AppVMs based on minimal templates startup and shutdown faster.
Debian-minimal templates seem to take up slightly less space than Fedora-minimal templates.
I am more familiar with Debian commands.
As for the splitting of Wifi and Ethernet, I made some launcher scripts in my Panel to set any or all firewall and VPN qubes to use either Wifi or Ethernet. This allows me to switch things up on-the-fly, and I can have Whonix through Ethernet and Clearnet or VPN through Wifi, or vice versa. I just wanted to share some ideas, in case you had not considered it yet. There are lots of options available to you.
If you get Bluetooth working, it would be nice if you could share your experience here or in a new post.
OK, I know this thread is from August. but everywhere else points me to it as being the “best” sys-audio minimal template setup thread.
I am completely unable to get sys-audio to see my soundcard. Other qubes are sending it sound; I can see the playback trying to happen, but my output is “Dummy Output.” So I think there’s only one missing piece of the puzzle, and that’s the sound card.
sudo alsactl init
simply returns alsactl: init:1759: No soundcards found...
The audiovm service is there, the soundcard is properly added as a device to sys-audio.
sudo qvm-start-daemon --all --watch
simply says:
sys-audio: GUI connected to dom0. Skipping
sys-audio: AUDIO connected to None. Skipping
Unless I make sys-audio the audiovm of sys-audio, then it reports:
sys-audio: GUI connected to dom0. Skipping.
sys-audio: Starting AUDIO
Loopback vchan connection not supported
libvchan_client_init: No such file or directory
My attempts to “autostart” pulseaudio and the daemon with those desktop files, by the way, failed; pulseaudio has to be manually started, and the daemon may or may not have started. (This time, it didn’t). EDIT–This is fixed
with the exception of alsactl init, all of the alsa commands pointed to in this thread result in command not found
, even though they are installed according to apt-get. That is true whether or not I run them as sudo.
I imagine you’ll want more info; please let me know what’s still missing. Thank you in advance.
Also: sudo alsactl restore
returns:
alcactl: load_state:1683: Cannot open /var/lib/alsa/asound.state for reading: No such file or directory
I’m beginning to suspect that somehow my alsa stuff isn’t properly installed.
My sys-audio displays the same output uness I perform the procedure outlined in my earlier post:
Each time I start QubesOS on my Librem 14, I run the following script:
#!/bin/bash
qvm-start --quiet sys-audio
qvm-shutdown --wait sys-audio
qvm-start --quiet sys-audio
qvm-shutdown --wait sys-audio
qvm-start --quiet sys-audio
sleep 3
qvm-run --pass-io sys-audio "amixer sset Master 0%"
This is also important:
If you have opted for a disposable sys-audio, then I would recommend testing my hypothesis. I did this by starting sys-audio and using the pavucontrol
package to check if “Dummy Output” changed to “Built-in Audio Analog Stereo” or not. If not, shutdown sys-audio and try again. If your sys-audio is non-disposable, then it might be unpredictable like my experience.
Hopefully this is helpful. Otherwise, maybe someone else could share their experiences.
