Hi, 

I've a LG 49SM9000 attached to a BeoLab 7.1 using Steve's (SoundsHeavenly) kit via the headphone socket. The sound routes ok, but I have two issues. The first is that there is a low level hum and a regular slightly louder static sound. The second is the volume on the tv only needs to be very low to be quite loud at the speaker. 

So tests done so far, connecting an iPhone and MacMini to the speaker via the headphone cable and all works perfectly. No hum or static. I've tried three headphones with the TV and again the sound out of the TV is perfect through them. So both ends seem to work fine, but not when connected together. I've bought a ground loop isolator, but that made no difference and when there is no output from the TV there was an even louder hum. 

Attached is a sound file of the issue. At about 0:10 / 0:06 / 0:04 is the louder static sound. 

Any advise would be greatly appreciated. 

Take care, Andrew.

Hi Andrew did you get this problem solved. I would like to buy a LG OLED 48CX6LB and attach my Beolab 7.2 to it using Steve's (SoundsHeavenly) kit via the headphone socket.

Hi to you both, 

Yes I did sort of solve the issue. It seems to be an issue with the audio coming from the TV being too loud for the speaker. I have this in-between the two...

What I find a little irritating is that I have a fairly highland TV and a very good speaker, but this piddly light wight volume control in-between. 

Sorry Steve, we last spoke about this at the time about a year ago. I've done a lot of searching about and cannot find an any more premium solution, or indeed anybody prepared to make me one. Fancy the task? :-) 

Take care, Andrew.

Hi Andrew,

Glad you were able to find a solution. I am sorry that I can't look into an alternative for you at the moment during the current UK lockdown, but this may be something that we can work on in the future.

Kind regards, Steve.
