How to prevent usb dac from going to sleep? Sound Blaster Play!4

Hi!

I have issue with my dac/sound card Sound Blaster Play! 4 which going to sleep after some time, and i need to reconnect it manually to get it work again. Even restart from volumio menu not wake up this dac.

It’s not completely unconnecting, it’s on the menu of dacs, but can’t play anything, no sound at all.

So how to prevent it from sleep? It’s annoying, that i need to walk to the raspberry and reconnect dac every time.

Volumio version 3.631
