Hi list,
I have now installed Pipewiere following the Arch Linux wiki.
One thing I don't understand is how to set Frames / Buffer for a device
and if / how names can be (permanently) changed.
I typically would have a bunch of Presets in QJackCtl and select those
based on:
a) the soundcard
b) the use case (higher/lower latency mostly)
With Pipwiere while qjackctl still seems to for connections etc. it
seems to 'ignore the preset settings.
My understanding is that with Pipewire (pipewire-jack?) installed it's
as if jack were always running and when jack applications start they
will be available via pipewire.
So the question is, is there equivalent (preferably GUI) functionality to:
a) select only one audio device to use with Jack (on my laptop I
typically don't care to have the on-board audio card if I plug in a USB one)
b) select a 'profile' with saved frame / buffer values (and possibly
sample rate) for that device
Regarding a) I can actually switch off a card manually from the KDE
audio settings (I'm using KDE). But it would be nice if for certain
cases for example the on-board card were switched off when a USB one is
plugged, and re-switched on when unplugged.
Also, it seems pipewire wants to use the full very long name of a device
making it very non-ergonomic in any application where this is exposed is
there a way to have shorter names (QJackCtl allows renaming, but that
seems local to just itself). For example my UMC204HD is called "UMC204HD
192k Direct UMC204HD 192k" in some instances.
About names, pipewire seems to like names like capture_FL or aux0
instead of familiar system:playback_1 which some applications (e.g. like
jack_capture) rel(ied) on.. Is there a way to change that? The name
makes even less sense for an on-board card which has just a stereo-in
and stereo-out.
Any hints or suggestions appreciated.
Lorenzo.
