changing default sound levels FC6

decrepit · 04-30-2007, 07:14 AM

Using FC6 with gnome as default, and kde for a few of it's programs.

I want to increase the default PCM sound level so I can hear my emails come in.
(getting old and forgetful, don't remember to adjust levels each time I boot.)

Found a similar thread on one of the other OS's forums. said to do a "alsactl store".
This works in as far as it changes the settings in /etc/asound.state.

But that doesn't affect the PCM level when I reboot.

So what file is controlling the sound levels???
And how to edit???

Open a terminal and type; alsamixer

Adjust your PCMlevel to your liking and press the 'Esc' key when done.

As root type: alsactl -F -f /etc/asound.state store

Thanks Lenard, but that is very similar to what I've already tried (I didn't have this bit, "-F -f /etc/asound.state") and has exactly the same effect.

ie, Alters /etc/asound.state fine, but has no effect on sound level when I reboot.
That's why I think there must be another file that gnome is using for default sound levels.

Any idea??

It was having the same effect with KDE, but there's a checkbox in sound set up called something like use last levels, since I've ticked that KDE levels stay where I've set them.

Sorry no, as I do not use Gnome. You might want to check around in the hidden .gnome2 and .gnome2_priviate directories.

Thanks again Lenard, but I don't see any thing that looks likely.

If I log into a terminal after booting, would you expect alsamixer to reflect the /ect/asound.state file? Or the levels in the gnome mixer???

menu --> administration --> sound, there you will find the test for sound and a slider that controls the hardware level of sound. By default, Fedora puts the slider half way across the horizonal bar. I would slide it to about 85% and redo the test.

There is also the software slider that usually sits in the top right hand corner (Gnome)

Thanks Lsatenstein,
Thought you had it there, I adjusted as you advised, but when I reboot, gnome volume control PCM is back to 51% and the System -> Administration -> soundcard detection slider is back about 1/2 way.

Here's the PCM entry in /etc/asound.state

control.25 {
comment.access 'read write'
comment.type INTEGER
comment.count 2
comment.range '0 - 31'
iface MIXER
name 'PCM Playback Volume'
value.0 29
value.1 29

I don't understand why it doesn't come up around 90%. Something is resetting PCM to 50%, but what????

You can try editing the /etc/modprobe.conf file and commenting out the line which looks something like (the line is commented out in the example below);

Code:

# remove snd-hda-intel { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-hda-intel

Thanks for being patient with this.
Tried that, volume still came up on 51% guess it's something else.
