But there is a remedy: You'll get for little money from 15 Euro already there quite good- PC speakers with USB port, so no extra power cord.
Speaker in the headphone jack, power they get from the USB connector on the TV and everything is good. This is not Dolby Surround, but I find this solution prima, because the small speakers take almost no space away and the sound is much better, absolutely ok for a second TV in a small room.
In addition, they hardly need extra power, they can be loud and quiet place on the remote and they are, as soon as the TV is off, well off.
The DVD Player- a nice goodie, also funktoniert, so all in all, down to the slightly-fix sound problem, a really good device for that price.
