If you have a file /etc/asound.conf copy this and paste it in. If you don't have a file /etc/asound.conf put this in a text editor and save it as /etc/asound.conf then reboot to change system defaults.
Some apps over-ride defaults, others you may hear a difference. Listen to some .mp3's or YouTube videos before and after and let me know how it works for you.
Code: Select all
## Linux usually defaults to "samplerate" but there are better converters
## put one of the following - samplerate samplerate_medium samplerate_best lavcrate
## lavcrate_high lavcrate_higher speexrate speexrate_medium speexrate_best
## in between " " below to choose rate converter.
## save file as /etc/asound.conf or copy/paste to existing
## /etc/asound.conf if you have that file already.
defaults.pcm.rate_converter "lavcrate_higher"
## resample quality - Linux defaults to 4
resample.quality = 10
## below sets low and high frequency cutoff. Linux usually defaults to 150/15000
## uncomment "channelmix.lfe-cutoff" to extend low frequencies (more bass if your speakers are capable)
# channelmix.lfe-cutoff = 60
## uncomment "channelmix.fc-cutoff" to extend high frequencies (you may notice a bit more "sparkle" on your audio)
# channelmix.fc-cutoff = 22000
