Wanted to love the unit as it worked perfectly when plugged in for a while. But then I noticed how after a while the volume would stay low when I start using it again after it stayed plugged in. I unplug the toslink cable and put back - same low volume. I unplug 5v DC and put back in - and volume goes back. Scared my toddler the first time I did that as the volume went up 10X :/ Returning this and looking for something more reliable.
