New Andromeda Trinity audio issues (kmix, pavucontrol, pipewire)?

globetrotterdk · 2026-02-22 10:15

I have just installed Q4OS Andromeda Trinity on a computer, and am experiencing audio problems:

Device-3 should be my default device. Multimedia codecs are installed.

The problem started with kmix, having to switch audio sources at each boot. Then at some point, kmix audio sliders stuck and couldn't be adjusted from 36%. So, I installed pavucontrol, set the default source and adjusted the volume output. Unfortunately, I don't get any audio at all.

$ speaker-test --channels=2
 
speaker-test 1.2.14
 
Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 64 to 1048576
Period size range from 32 to 524288
Periods = 4
was set period_size = 12000
was set buffer_size = 48000
 0 - Front Left
 1 - Front Right
Time per period = 4,996887

Works, but no sound... YouTube in Chromium and Waterfox works, but no sound...

Any ideas how to solve this?

Good day!

You have a very specific device, so, you will have to "dig and try" by yourself. This is a normal thing, since we can not effectively help you, because we do not have this device and can not test it by ourselves.

First, you can try to change the aRts settings.
Go to Settings - Sound System.
There tick Enable sound system, Run with maximal priority, Sound buffer 46ms (8 fragments, 1024 bytes).
Then in Equipment tab (or Devices...sorry, I use Russian translated interface) Select sound device: ALSA, then tick Full Duplex, Then Sampling frequency 48000Hz (Normally you should select 44100Hz, but for your device 48000Hz is needed), and Quality 16bit.
Then reboot and in terminal type artsplay /opt/trinity/share/sounds/KDE_Startup.wav
If you can not hear the sound, then temporarily disable aRts, and try to play using ALSA player.
artsshell terminate
aplay /opt/trinity/share/sounds/KDE_Startup.wav

There are some problems with this device and PulseAudio.
Please check these links:

That jackdbus autospawning thingy had me puzzeld for a while too. Seemed impossible to kill Jack. If I want to stop Jack I always run:
Code: Select all
pkill -9 jackdbus
killall jackd
That works and no mysterious Jack spawn. Killing Jack is needed to run PulseAudio. And without Pulse, no audio in Firefox.

Many thanks for the replies. On one of my reboots, the audio suddenly started working. I will leave the topic open for a few days, but right now it somehow is solved...
