Audio totally disappearing randomly

[BlueDragon]

Thanks again, I will step by step try these various commands, after I had the problem again.

Now I'm starting to think that maybe there is somehow a connection with an Avantree usb-stick (DG-60), working as bluetooth dongle / audio transmitter. I'm using it from time to time but not these last days. Hence I need to test all this over a couple of days. I'll give a feedback for sure.

So here the first feedback, more will follow.

2-3 days passed without the audio to disappear and then it happened again, without having used the Avantree USB stick (mentionned above). So this rules out this cause. Then already a big thangs to Dolphin, who is always pointing in a good direction, which I appreciate very much. Very likely the cause will remain to be discovered but it's already great not to have to log out and in again (having to save all open stuff and log in everywhere again), to regain a working audio functionality. So a single liner, as Dolphin suggested, takes care of the proper resetting:

try resetting pipewire

Code: Select all

pkill pipewire; pkill pipewire-pulse;pkill wireplumber; pipewire-start

Now remains to somehow find out, what causes pipewire and / or wireplumber to malfunction? Any clue?

If it was just after a suspend & wake up it would be easy (we would make that command auto-issued , also it would be easy to understand why it stops working..). Till then, as you might already know, you can create hotkey(s) and/or launcher with that command, then just press your key(s) or click the icon on panel etc...

Getting an "Audio" section of your QSI when the sound has gone missing could be of some help. Both the Nvidia and integrated sound chip are using the intel snd driver, though.

Presently I can add this information. Just typing pipewire-start is already enough to have the audio comming back.
Follows a couple of warnings and infos:

Getting an "Audio" section of your QSI when the sound has gone missing could be of some help. Both the Nvidia and integrated sound chip are using the intel snd driver, though.

Just compared to the initial QSI and it seems the wireplumber has been disabled. Anyone knowing the in-depth maybe, as to what could cause that? (Honestly I haven't a clue about what wireplumber is, I'll need to read about it. )

EDIT:
"WirePlumber manages and routes videos and audio streams to appropriate channels. It’s also a policy manager which makes decisions about how the video and audio are handled.
For instance, when we record audio on a browser, WirePlumber detects the available audio recording devices attached to the system. Then, it decides where to route the audio stream. In the case of mic disconnection, WirePlumber channels the audio stream from another input device."

Though it's not helping me much.

EDIT 2:
That's even a better definition...
"WirePlumber is a modular session / policy manager for PipeWire and a GObject-based high-level library that wraps PipeWire’s API, providing convenience for writing the daemon’s modules as well as external tools for managing PipeWire."
