Hi. I'm trying to connect my QLED to my Bose SoundTouch 30 speaker. The speaker only has a 3.5mm audio jack. I've bought an optical to 3.5mm lead to connect the TV to the speaker. When I select Optical as the sound on the TV and Aux as the setting on the speaker it should then work.....but it doesn't. No sound at all. I also have smaller Bose SoundTouch 20 and 10 speakers and I have tried the same with them too - the result is the same. I'm wondering if there's something I am not doing right or if there are compatibility issues with this TV and these particular Bose speakers. Thanks!
