Apple TV mirroring no sound.

[HappydaysArehere]

Tried to mirror tv programmes from iPad. There is no sound on the TV. Can watch directly from iPad with no trouble. Has anyone else had this trouble? Any ideas would be gratefully received.

Googled the problem and found this, hope it helps.

Thank you widower. I am going to have another go. For some reason I couldn't get into settings when I tried before. Will try the cable removal.as on the web site. You are always around to help. You are so kind. Thank you again.
