# GUI
qpwgraph works just like qjackctl
# Scripting
# pw-link
Manage IO connections. Takes the place of jack_connect
, jack_disconnect
and jack_lsp
# Issues
# Volume very low
# Set volume using a mixer tool
- alsamixer
Use
alsamixer
tool and set the output gain to whatever.- See also https://wiki.archlinux.org/title/PipeWire#Low_volume
You can store the alsa config by using
alsactl
sudo alsactl store
- pavucontrol
Pipewire works with Pulse audio, so pavucontrol should work as well. In fact, I had better luck with this to set the volume level my Xone k2
- amixer
Like alsamixer, but CLI only (no TUI)
# Multiple sound cards
By default pipewire handles multiple sound cards timing by resampling. In pavucontrol you can set the Pro Audio profile on the card which, amonng other things will assume all devices share the same clock.

# Timing
Instead of letting pipewire handle timing by resampling, which I found to be less than perfect, we can use a module-loopback to introduce a delay on one or more devices.
See also pulseaudio for how to set that up
