Hi,
thx for the detailed description, but probably I couldn't make clear, where my problem really is. Its not about pipewire - I only wanted to say, that for pipewire I found the only snippets of documentation for rtkit. Instead I wanted to know, how to configure rtkit for other applications like Citrix Workspace.
You cannot "configure rtkit for other applications". rtkit-daemon listens on requests over D-Bus and fulfills (or denies) these requests. If your application does not talk to rtkit-daemon, there is nothing you can do from the rtkit side. If your application does request to become real time but request is denied, we could look why.
Bye. Michael.

Hi *,
is there any documentation on how to configure rtkit-daemon for openSUSE?
I don't know it.
[...]
Especially I have the following questions:
Do I have to put a user in the rtkit group, if he wants to run a program like Citrix, which requests realtime capabilites?
Yes, add your own user to rtkit group.
This configuration enables pipewire daemon priorities to change in real time.
Or do I have to create a config file in /usr/etc/security/limits.d/? Is so, what should it contain?
This is not necessary.
Do I have to configure something else?
Right.
0. Confirm installatin by
$ pactl info
Ex. this is mine;
Server String: /run/user/1000/pulse/native Library Protocol Version: 35 Server Protocol Version: 35 Is Local: yes Client Index: 77 Tile Size: 65472 User Name: masaru Host Name: localhost Server Name: PulseAudio (on PipeWire 0.3.70) Server Version: 15.0.0 [...] Cookie: fb04:87e4
Before you proceed, you should do the following as preparation;
1. if possible, uninstall the wireplumber and install pipewire-media-session
The reason is that pipewire-media-session is obviously better sounding than wireplumber.
3. I assume this is done when pipewire is installed, but I'll mention it here.
$ sudo cp /usr/share/doc/pipewire/examples/alsa.conf.d/99-pipewire-default.conf /etc/alsa/conf.d/
4. $ mkdir ~/.config/pipewire
and.
$ mkdir ~/.config/pipewire/media-session.d
5.
5-1. Change alsa API to pipewire-alsa
$ touch ~/.config/pipewire/media-session.d/with-alsa
5-2. Enable bluez5 module
$ touch ~/.config/pipewire/media-session.d/with-pulseaudio
6. for the pipewire's settings
6-1. $ cp /usr/share/pipewire/pipewire-pulse.conf ~/.config/pipewire
$ cp /usr/share/pipewire/pipewire.conf ~/.config/pipewire
6-2. edit conf files
6-2-1. for pipewire-pulse.conf
[...] stream.properties = { #node.latency = 1024/48000 #node.autoconnect = true #resample.quality = 4 #channelmix.normalize = false [...]
to
[...] stream.properties = { #node.latency = 1024/48000 #node.autoconnect = true resample.quality = 15 #channelmix.normalize = false [...]
where 15 is maximum number, which means best sound
6-2-2. for pipewire.conf
## Properties for the DSP configuration. #default.clock.rate = 48000 #default.clock.allowed-rates = [ 48000 ] #default.clock.quantum = 1024 #default.clock.min-quantum = 32 #default.clock.max-quantum = 2048 #default.clock.quantum-limit = 8192 #default.video.width = 640 #default.video.height = 480 #default.video.rate.num = 25 #default.video.rate.denom = 1 # #settings.check-quantum = false #settings.check-rate = false # # These overrides are only applied when running in a vm. vm.overrides = { default.clock.min-quantum = 1024 }
to (in my case with USB-DAC)

Generally, when pipewire is installed, the sampling rate is 48KHz.
To know the operating status;
$ cat /proc/asound/HDAMP1/pcm0p/sub0/hw_params
In my case:
access: MMAP_INTERLEAVED format: S32_LE subformat: STD channels: 2 rate: 384000 (384000/1) period_size: 256 buffer_size: 32768
I am enjoying musics with mpd+cantata in this environment.
If you use mpd, please let us know again.
Regards & Good Night.
