Voice goes to internal speaker on dell optiplex 790

Post by mr_mke » Fri Nov 03, 2017 11:07 am

I have a Dell Optiplex 790 with linux mint 18.2 x64 cinnamon. I have this awkward sound problem when I play a video or sound clip on VLC or open a youtube page I get the music on the sound card and the voice on the internal speaker of the system. Also there is this echo as if the sound is played inside a large hall or inside of a bathroom. It sounds like there is some sort of filter active on the sound card but I don’t know where could this be. I tried fiddling with alsamixer and changing the sound card from default to hda intel and back with no success then tried reinstalling alsa and pulseaudio after burging them also with no success. Below is the configuration extracted from running inxi terminal command:
