PulseAudio configuration

[simple115]

Hello guys, recently I installed Ubuntu 18.04 and so far it's great. But the sound quality is very bad (even terrible). I know that you can configure PulseAudio to make the sound quality better but I don't know how, and nobody wants to help me.

 

I posted this topic in 3 other forums and nobody wants to help me. If someone can help me i will be very thankful!

Describe what you hear.  Is it HDMI/DP, OnBoard or a Soundcard?

 

I had to do this for my box

It's from laptop speaker. I got help from another forum and i installed pulseaudio equalizer and from this i changed pulsefire audio and right now the sound is good.
