And do the headphones have any pause control? I don't know if VLC and Winamp react to it. At least in my case, Winamp reacts to the Pause button on my keyboard, but IDK if that is similar to pressing a Pause button on a BT speaker.
Have you tried them on another computer, or even a cell phone?

@capitanremo said in Youtube and Soundcloud stops playing after every minute:

It hapens in opera, with youtube and with soundcloud

So it does not happen with other browsers?
