I´ve built new HTPC with AMD A8-9600 and installed Mint 18.3 Sylvia 64-bit Cinnamon onto it. I have it connected to my Samsung TV via HDMI cable. Video works fine but I can´t get any audio to be heard. I have searched this as well as other Linux forums and tried various solutions but so far nothing worked for me, TV speakers remain silent.
Below is my system info:

There are attached screenshots from Sound settings and PulseAudio which all seem correct to me...
Please give me some suggestions what else should I try because I´m really stuck and have no idea what could be the problem with my configuration, thanks.
