unable to run with Debian Trixie and Raspberry Pi 4

[etiennedemoulin]

Hi,
Trying to run a basic audio example using a Raspberry Pi and Raspbian 13.
Pipewire is on version 1.4.2
Following the basic tutorial I installed pipewire-jack with apt install pipewire-jack
I get this error while loading a basic audio example
Error: cpal backend error during default_output_config: DeviceUnavailable: The requested audio device is not available. It may have been disconnected.

Is there something I'm missing ?

found a solution doing severals things (https://wiki.debian.org/PipeWire)

1. installed pipewire-audio-client-libraries and libspa-0.2-jack
2. cp /usr/share/doc/pipewire/examples/ld.so.conf.d/pipewire-jack-*.conf /etc/ld.so.conf.d/
3. rename /etc/ld.so.conf.d/aarch64-linux-gnu.conf with 0-pipewire-jack-aarch64-linux-gnu.conf
4. sudo ldconfig
5. reboot raspi

Thanks for reporting and sharing a fix. What audio output device did you use on the RPi?

I use a Focusite Scarlett 4i4
I achieved to access only the first 2 channels with this interface. cf #198
