Description Sérgio Basto 2012-11-05 16:31:23 UTC

Hi,
Though this is the right place to report. 
I got this bug opened on Fedora ,
https://bugzilla.redhat.com/show_bug.cgi?id=704839
seems no body cares , but on a laptop when we want hear without
headphones it helps a lot.

1st - edit /etc/pulse/client.conf
and change
autospawn = no

2nd - killall pulseaudio

3rd - run on user env:
pulseaudio -vvv

lets test with kmix I see on pulseaudio logs at maximum :

D: alsa-sink.c: Requested volume: 0: 100% 1: 100%
D: alsa-sink.c: Got hardware volume: 0: 100% 1: 100%
D: alsa-sink.c: Calculated software volume: 0: 100% 1: 100%
(accurate-enough=yes)

with gnome-control-center -> sound I see on pulseaudio logs at maximum :

D: protocol-native.c: Client gnome-control-center changes volume of sink
alsa_output.pci-0000_00_1b.0.analog-stereo.
D: alsa-sink.c: Requested volume: 0: 153% 1: 153%
D: alsa-sink.c: Got hardware volume: 0: 100% 1: 100%
D: alsa-sink.c: Calculated software volume: 0: 153% 1: 153%
(accurate-enough=no)

so how I put kmix also control "software volume" ?

Honestly, I do not understand this wish. It has so many links i do not know where to start. In any case, can't you use http://alsa.opensrc.org/Softvol ? It says, you have to restart KMix once, but that should not be a problem. Are you uisng direct ALSA or Pulseaudio?

I use pulseaudio, pulseaudio use ALSA, and ALSA had implemented "sofvol"

Just read my initial comment, why with gnome-control-center -> sound, I can get more 50% of volume than kmix ? .

Comment 4 Christian Esken 2012-11-12 19:57:31 UTC

The 150% thing is a Pulseaudio thing. I don't  think it has anything to do with ALSA Softvol - this is why the links confused me. In any case, there is already a wish about that, thus marking this as a duplicate.
