I installed Libreelec (with Kodi) on the Raspberry Pi2 and I did connect it to a PC Monitor (HDMI). PC Speakers connected to the monitor or even to the Raspberry Pi (3,5 mm jack) give me poor sound quality.
I am undecided, what to buy in order to improve sound quality. For reason of space in my room I would like to buy a small soundbar (like Bose solo 5 or similar) but since I'm not an audio expert, I am not sure if it would be a good idea.
First of all - how would I connect the soundbar to the monitor given that I have only one hdmi port (the second one is mhl-and it seems is not working). The Raspberry Pi also lacks of audio inputs. I believe that a 3,5 mm jack connection would also give poor sound quality.
If is necessary I could buy a cheap audio adapters or one of those products from brand Hifiberry (DAC or AMP?) but I am confused and don't have the knowledge to choose the right thing.
