Hint for buffer delay setting is inaccurate if pipewire is used

[jose1711]

Describe the bug
Hint for Settings/Buffer Delay shows:
.. On Linux, use the JACK configuration tool to change the buffer size.

If a user is using Pipewire this text does not help much - changing the buffer size in - say QjackCtl has no effect. Instead jamulus needs to be started like this (for 128 samples):

PIPEWIRE_LATENCY="128/48000" jamulus

As Pipewire is being adopted by more and more Linux distribution, hint should be improved.

Operating system
Arch Linux, x86_64

Thanks for the report. Would like to submit a PR?

Note: This will likely not make it into 3.8.2 anymore as we are in translation freeze phase (beta) already. But future versions would certainly benefit from that clarification.
Pipewire users might have the benefit that Jamulus will work out of the box for them, so they might not even know that they are using pipewire.

I would better pass than on to those with better level of English than me 😄

Yes, I can confirm that (no need to start with pw-jack or first starting qjackctl to start Jack first). Hmm.. thinking about this.. could hints be generated dynamically during the startup (why show Linux-related stuff to Windows users and vice-versa)?

(why show Linux-related stuff to Windows users and vice-versa)?

The audio controls that are specific to one audio subsystem should only be being shown for that audio subsystem. JACK isn't OS-specific, of course.

However, plenty of non-OS-specific controls may have OS-specific niggles - these are generally dealt with at compile time.

Sorry for the maintenance noise here.

To me it seems a bit difficult to proceed here. @gilgongo @jose1711 @mulyaj do you have any other suggestion on how to move this forward? I think

On Linux, use the JACK configuration tool to change the buffer size.

Could be reworded to

If using JACK, use the JACK configuration tool to change the buffer size. Other APIs like Pipewire might need different (command line) options. Please look in their manual.

I think this is good.

Hopefully, #2645 will close this.
