Low/poor audio quality

[emanditarun88]

I was a windows user, recently installed Linux mint 20.1 and I'm a beginner. My linux experience till now is so good than the windows. The only problem i have now is the audio quality. The audio on my laptop is too low and the audio is too bad when i increased the max volume to 150%.
Please suggest me ways to fix or improve the audio quality.

please let me know if i need to post any other details.

Hi emanditarun88,

Let's get a look at your sound setup with this command:

Code: Select all

curl https://gitlab.freedesktop.org/pulseaudio/pulseaudio/raw/master/src/utils/pa-info?inline=false | bash | nc termbin.com 9999

The last line of output will have a URL pointing to the info. Pasting that URL is all I need.

There very end of the output got chopped off. Please run this so I can see the rest of it:

Code: Select all

dmesg | grep -C1 -E 'ALSA|HDA|sof|HDMI|snd[_-]|sound|hda.codec|hda.intel'

So far I don't see anything obvious as to why the sound isn't decent. Is Windows still on this machine?
