Laptop's speakers sound bad. Poor sound quality
According to https://forum.manjaro.org/t/solved-terrible-sound-in-linux-much-better-in-windows/8203/6 and http://www.alsa-project.org/main/index.php/Asoundrc
We have to do some manual settings editing on pulse audio config. The path is /etc/pulse/daemon.conf
. Open a terminal by pressing ctrl+alt+t. First of all, backup the configuration file:
sudo cp /etc/pulse/daemon.conf /etc/pulse/daemon.conf.backup
Then type sudo nano /etc/pulse/daemon.conf
(If your file is empty, it means the file you are looking for is not in this directory. In this case, try to locate it:
sudo updatedb
, this will update your files database index. Then type locate daemon.conf
to find the file location. Replace /etc/pulse/
with the path to your daemon.conf file)
Find the following lines (ctrl+w to find text in file) and replace your values with the following (lines might be in a different order in your system):
default-sample-format = float32ne
default-sample-rate = 48000
alternate-sample-rate = 44100
default-sample-channels = 2
default-channel-map = front-left,front-right
default-fragments = 2
default-fragment-size-msec = 125
resample-method = speex-float-5
enable-lfe-remixing = no
high-priority = yes
nice-level = -11
realtime-scheduling = yes
realtime-priority = 9
rlimit-rtprio = 9
rlimit-rttime = -1
daemonize = no
Press ctrl+o to save changes, then press ctrl+x to quit
now type nano ~/.asoundrc
in terminal and paste te following code:
pcm.!default {
type plug
slave.pcm hw
}
This will bypass dmix for pulseaudio increasing sound quality by a lot. We can’t have more than one resampler because if we do it gets resampled twice and some sound quality is lost (as explained by Calthax in this thread).
