Bluetooth and/or wireless headphones are not the sole cause.
This has been a tough problem for many people to solve because there can be many different causes. There's no single solution. For me and my wife, we've never been using wireless headphones. We use wired speakers that connect to the audio jack of our Windows PCs.
My problem was likely tied to DLL conflicts and/or old DLLs. My fix was very labor intensive. I'm glad whenever anyone finds a resolution, but again, there's no one cause.
That will be a temp tin mate. This problem is from spotify. The anoying tin is that spotify not making any effort or even trying. And we still keep coughing out money but we complain about sky, bt customers service etc at least they have got one n made the effort. I will be switching to Google music. Better support or neptunes i think the othet ones called. Excellent customer support n with phone num. Think i might have got the app name bit wrong. Am done paying for this ungrateful twats **bleep**.
