My in laws live abroad & skype once/twice per week.
but they never, ever turn their TV off/volume down & we struggle to hear them! Despite us saying we can't hear them, they shout over the volume of their TV & repeat themselves numerous times.
Also, they watch TV programmes whilst skyping. So we are sitting looking at them, looking at their TV!!
It's not like we Skype them at inconvenient times, they Skype us (they text to see if it suits so it's mutually convenient).
They're lovely people, we enjoy hearing from them, but it's so bloody frustrating!!
Not sure if I'm looking advice, we have asked them if they'd rather watch their programme & Skype after but they don't seem to take the hint.
Calls can last up to an hour with them shouting over the TV & our patience running low 
I know it's a first world problem but they've just finished a Skype call & I didn't hear half of it due to the volume of their TV.
