Soundtouch 300 soundbar sound only from middle speakers
I have My soundbar Soundtouch 300 connected via ethernet and via optical soundcable to my TV (recent model LG OLED 55")
However if I play movies on my TV the sound is good and balanced in range, but has verry little stereo or sorround feeling.
If i listen to the sound close to the soundbar, it seems that the outer speakers are not making much sound. Almost all the sound/volume is coming from the middle of the soundbar.
I tried playing a surround sound demo such as https://www.youtube.com/watch?v=A4KYoQKAnoE via HDMI & my MAcbook PRO and still have that same 'mono' sound feeling.
The surround feeling is even much better on my apple macbook pro with this movie then on the soundbar.
Am I doing something wrong or should i change some settings? Or maybe the outer speakers are not working well?
Thanks for any answer that can help.
