Sounds unexplained

I wrote some time ago about my father's studio and the sound of television coming from it after he had died and all the furniture and connections had been removed. We took on a firends furniture - deposited in the studio and the sounds stopped!

Our younger son has returned to stay here for a while and has removed most of the furniture we placed in the studio so that he has more room to work on a project he is engaged in finishing.

Yesterday about 2 in the morning I awoke to once again here the sound of old movies - I got up and wandered round the house thinking that someone had left a TV or a Radio on by mistake. Nothing!

I returned to our bedroom - which overlooks the Studio - and sure enough the faint sounds were coming from the studio! What will happen next!
