Subject: [PATCH] gnu: home: home-pipewire: Add extra-content to configuration.
Date: Mon,  2 Dec 2024 22:16:28 +0100

This allows for setting the default sound card/device, e.g.:

    pcm.!default {type hw card 0 device 2}
    ctl.!default {type hw card 0 device 2}

* gnu/home/services/sound.scm (home-pipewire-configuration)[extra-content]:
New field.
* gnu/home/services/sound.scm (home-pipewire-asoundrc): Append it to
"asoundrc".
* doc/guix.texi (Sound Home Services): Update accordingly.
