A periodic annoyance with my 10 year old system is that a number of tracks can stutter on playback. It is NOT interference. I have two original Play 1’s on stands in a stereo pair connected by ethernet into a Devolo dlan 1200+ powerline adapter. If interference was the issue it would not manifest in the same position from within a track. The afflicted audio tracks are also not damaged as they play on any other device without problem.
This problem only surfaced about a year ago but I doubt it could it be some component breaking down as the symptoms would not be so specific.
I did a test whereby I produced another playlist containing one troublesome track. Trouble is after trying to play it access was denied by my computer. This is still an ongoing problem with adding music from ‘My music folder’ when it resides on an external drive.
I have given up hope with the system as it still has annoyances that have not been refined or streamlined in years, particularly in regard to sorting or searching within the playlist being shown within the controller window. The stuttering issue is just another straw that will probably break my camel’s back.
