OK. on laptop today, can listen to music but if I play anything from you tube or any other video links.....no sound. Same on Facebook, no sound. Mute not on. Does not make sense.
Also my very old Nokia phone that I just keep for work calls, has now developed sound problems. If I make or answer a call, nobody can hear me but I can hear them, volume up full. Do speaker go belly up on mobiles.
I know that as I am over 50, the ears can breakdown but technology should last longer
