PipeWire integration discussion?

[oops]

...not likely. right now the required pipewire packages are not backported to mx19 or to debain 10 buster.

OK, thanks for the info.

FI: Tested into Icewm on MX21 amd64 and x32 ... that works great too ($ pactl info) :

Code: Select all

# ============ launch pipewire into IceWM startup ======================
export XDG_RUNTIME_DIR=/run/user/1000

#start pulseaudio before volumeicon so unmute works
#start-pulseaudio-x11 &
#launch pipewire
pipewire-start &
sleep 

#then 
volumeicon &
# ==================================

after successfully installing pipewire on MX21 Fluxbox, I noticed following (rtkit-related) dbus error-messages in ~/.xsession-errors :

Code: Select all

I assume that installing the rtkit package would take care of most of these errors; but aat the same time realize that this is basically a systemd component.
Is it safe to install/run it on my sysvinit setup?

Should be

Should be

I'm seeing the same messages running constantly, should rtkit be a dependency of the pipewire setup package then? These could balloon the User xsessions errors file over time.

It odd that PipeWire's server is calling for it constantly and yet upstream hasn't made rtkit a dependency, nor have I seen it mentioned obviously in any of the PW wikis I've skimmed.

installing rtkit did not remove my messages. got rid of a few, but not all. but I only got one set, at startup. they didn't keep hitting. I'll try to watch for that tonight.

Hi,

Perhaps for future Packaging consideration, here is a tool being developed to easily change the PipeWire Audio settings which currently are cryptically buried in the config files, I'm not thrilled that it relies on a KDE lib though, I would guess something simpler using simple QT or even Yad could probably be developed, unfortunately that's a bit beyond my current scripting skills... Perhaps a similar or adapted MX Tool could do the same. For people doing Pro Audio work on Linux the settings and parameters are important and one of the biggest complaints about PipeWire is that is is not easy to change params, this would change that..

Hi,

Obviously there will be continuous new releases of PipeWire and there's little sense in taking valuable Packager time to put every release in MX Test, the 0.3.60 release has some important fixes that may be worth looking at an update so just passing that along:

https://www.phoronix.com/news/PipeWire-0.3.60-Released

This point in particular looks of interest:
- The alsa plugin will now only start playback when there is data. This results in better sync and lower latency between capture and playback.

pushing up a new pipewire-setup-mx package, because the the new pipewire packages in test will probably cause pipewire-setup-mx to be removed if upgraded. and then sound won't work on sysVinit.

basically the old pipewire-setup-mx conflicts with the newer pipewire-alsa packages due to the new pipewire-alsa package providing more .conf files OOTB.

Thanks dolphin_oracle!

Absolutely will… lol spent hours yesterday with it pulsesudio was masked on the systemd side but not in sysVinit. No jack or alsa in available in pipewire.
Pipewire-setup-Mx gave a error 1 in the installer window. Everything was from the Mx back ports.

I used the MX xfce dec snapshot on a usb drive…1st as a live usb as that didn’t work I installed to the usb drive
and that worked as described above….will try with the new package when it’s available.

Thanks that setup package saves a lot of configuration
