Ubuntu 24.04 and Linux Mint

Ubuntu 24.04 (and subsequently Linux Mint), have a bug with managing the GoXLRs channels resulting in it presenting as a 'Multichannel' device. This is due to an issue in the alsa-ucm-conf package, which was resolved shortly after the release.

To fix this on your distribution, you need to manually apply a fix:

• Using sudo, open /usr/share/alsa/ucm2/common/pcm/split.conf
• Locate Line 329
• Change Empty "${var:__Device}" to Empty "${var:-__Device}" (Note the additional -)
• Save and Exit

Once that change is made, you should be able to re-plug your GoXLR and the channels will come up correctly.
