Not sure if this point has been raised before. If so sorry but I have been unable to find it.
I often use my echo dot to stream a playlist from my Amazon music. Recently, I noticed that the music sounded rather dirgelike - playing more slowly than it should. I checked and found it was playing slowly - it took 4 minutes 2 seconds to play a song 3 minutes 51 seconds long. The music plays quite smoothly - just slowly. Any advice would be appreciated.
