Audio device disappears when M2 Studio goes on sleep

I've seen this being complained about earlier but all the answers were standard non-answers.

USB Audio interfaces (in my case an SSL2+ via USB-C on a M2 Studio Max) disappears every time it goes on sleep mode. I have to unplug and replug the USB for it to show up again.

Again, there are MULTIPLE similar questions in these forums and ALL OF THEM have standard useless non-answers linking to articles like this one or this one. The problem is that the whole device disappears as if it's not connected. Sometimes the same happens to my USB-A keyboard.

Please provide actual possible fixes.

Thank you!

One work-around, is to disable “auto computer sleep” and only allow the display(s) to “turn off” when not in use.

To meet energy-star requirements, Macs go into low USB- power mode when they sleep.

This drops the primary bus power and provides only standby bus power.

If your bus-powered devices and bus-powered drives are not ready to elegantly transition in and out of standby power, they may disconnect.

I had this exact problem (M2 Studio Max and SSL2+ via USB-C), and after changing the USB-C cable (with USB2 data standard) to a Thunderbold 3 cable, this problem disappeared. Worth a try. Maybe a full fledged USB-C 3.1 gen 2 will work as well?
