Tinny sound on Lenovo U510

I want to ask, how can I tweak my sounds from speakers. It now sounds so tinny, like the sound comes from a tin can. In Windows, I don't have any problems with it, but in Ubuntu it sounds just awful.

In search of a solution, I spent approximately six hours. I tried to reinstall the alsa drivers, tweak settings in alsamixer and I also try to restart pulseaudio. Nothing worked for me.

The off sound can be heard when someone in the track (sound) speaks a bit louder. When someone speaks normal, it's little bit better, and when I lower the volume it sounds even less tinny, but it can still be heard.

Do you have any tips?

I'm having this issue on a Lenovo Ideapad U510 with Intel Core i3. I am running Ubuntu 14.04.

you can try with alsamixer with the terminal. You can change the type for channel and have the level sound for the speaker changed.
