Powersave: sometimes no sound after restarting playback

Hi all

I had to disable this plugin because the main player would not output any sound, even though playback had been started en the progress bar was showing playback.
Rebooting seemed the only option; restarting Squeezelite and/or LMS would not help.

Any idea what might be wrong/how to solve this?

TIA!
