[alsa-devel] Default volume for all soundcards (-20dB by default?)

[Jo]

Thanks David for your answer !

I tried this in /usr/share/alsa/init/default  but it doesn't change
anything (-20dB again on next reboot) :

# Default ALSA volume levels and setting when initialization database fails.
# [...]
#
# **************************************************************************
# playback
# **************************************************************************

ENV{ppercent}:="75%"
ENV{cpercent}:="75%"
ENV{pvolume}:="-3dB"



This sentence

# Default ALSA volume levels and setting when initialization database fails.

seems to show there is another database elsewhere, where should I try to
set -3 dB ?
