Reboot needed to restore USB audio

[oldwood]

Maybe unpluging the DAC before going in suspend?
Not really a solution but... it's better than buyng a horseshoe and a four-leaf clover.

We stream a radio station and like to listen at night while drifting off to sleep. The amp and the laptop are set to sleep but the Amp/DAC goes to sleep before the laptop. The amp triggers the DAC to shutdown so the OS sees it drop out and this is probably why I need to reboot to get it back.

Tonight I am going to unplug the trigger so the DAC will not shut off when the amp shuts off. Not a great solution but I think the power usage is pretty low.

If this works I could set it up so the Amp/DAC go down after the laptop and that should work?

Thanks for the help.
