In the link above, they say
- Fixed an underlying issue which could lead to USB audio devices going to sleep after 1 minute of idle time, and not waking up until the PC was rebooted
Going to sleep after inactivity is I think the issue here in this thread. However, for most people the devices do wake up and no reboot is necessary. It is just that the on/off is very annoying. I mean *very*, as here are some pro users and that could mean that your active speakers pop. As they do when you turn off and on the USB devices.
That would be at least exactly my issue. The USB interface turns on and off all the time, and my speaker pops with it.
