Hardware: Lenovo Thinkpad T420i
Problem: Sound is working, but it isn’t loud enough
Solution:
Create a file /etc/asound.conf and paste this config:
pcm.!default {
type plug
slave.pcm "softvol"
}
pcm.softvol {
type softvol
slave {
pcm "dmix"
}
control {
name "Pre-Amp"
card 0
}
min_dB -5.0
max_dB 20.0
resolution 6
}
Restart ALSA (/etc/rc.d/rc.alsa restart) and there should be a new mixer channel called pre-amp in the mixer software (kmix/alsamixer). And now, my laptop is ready to rock..
