USB Audio Device cannot be selected but appears in USB-DEVICES

  • 772

The device is a Maono Maonocaster C2 Neo. Ubuntu 24.04.

I can select the device for both input and output using Audacity when routed through the JACK server but I cannot use it for general system audio.

This is how it appears when listed with usb-devices.

Is there a way to force Pulse to "see" this device and let me select as system in/out ?

    Almost as quickly as I post my question I find a solution for an older version of Ubuntu.

    Remove and purge both alsa-base AND pulseaudio, remove the user configuration for pulse, reinstall both, force a reload of alsa and then restart the machine.

    Listing all sink devices now has my Neo appear with the bizarre name of RemoteSL + ZeroSL Analog Stereo.

    sudo su
apt-get remove --purge alsa-base
apt-get remove --purge pulseaudio
exit
rm -rf ~/.config/pulse/
sudo su
apt-get install alsa-base
apt-get install pulseaudio
alsa force-reload
shutdown -r now
