Reboot needed to restore USB audio

[oldwood]

Hi everyone,

I am new to Linux Lite. I have it installed on a Asus laptop and I am using USB out to a Emotiva XDA-2 DAC for music. It works well but in the evening I turn off the DAC and  in the morning I need to reboot in order to get the OS to find the USB audio channel.

Is there a CMD I can use to re-scan for the USB audio output? I have tried re-plugging the USB cable but that does not work.

Any input is greatly appreciated.

Thanks
