how to turn off sound by default?

[att]

Hello,

Sorry, for such a stupid question, but I want to boot Porteus-KDE (1.0 1.1 1.2 rc1, whatever version) and I want KDE to start with sound set to silence by default.
Things that I tried myself, and which did not work:
* I tried to edit /etc/rc.d/rc.alsa and I set every "set" value to 0% - did not work - kmix still came up with 74% volume.
* I replaced rc.alsa with a dummy echo file (echo "alsa off!") - still does not work - kmix still comes up with a volume set to 54%.

Now I am out of clues. Thus:
Which config file do I have to edit to get a sound volume of 0% correctly, every time I start?
Where is the config file with the waveform-file (wav-file) so I can replace the startup-sound manually?

I prefer to use /rootcopy method to change config files. Any clues are appreciated.

nosound as cheatcode at boot up should solve your problem.

Hi att,

The 'volume=' cheatcode has been added for this purpose, so in version 1.2 rc1, all you need to do is add the cheat to your boot line as, 'volume=0%'

In version 1.1, you could add the following lines to /opt/porteus-scripts/paths and place the modified version in your rootcopy:

Code: Select all

# Set volume
VOLUME=`egrep -o " volume=[^ ]+" /proc/cmdline | cut -d= -f2`
[ "$VOLUME" ] && amixer set Master $VOLUME

In version 1.0 or 1.1, I think you could probably use the same code in /etc/rc.d/rc.local, generate another script just with those lines and set it as part of your Desktop Environment's autostart, or perhaps boot with: 'autoexec=amixer~set~Master~0'. I'll check on that...

Posted after 5 minutes 29 seconds:
I just tested with 'autoexec=amixer~set~Master~0' and it worked -- that's probably your easiest solution for V1.0 and 1.1.

Hamza's suggestion would be even easier, but I believe it would disable the detection of your sound hardware altogether, so you wouldn't have sound even if you turned the volume up after logging in.

The "nosound" boot parameter did not work for me. Furthermore, it is not documented anywhere, also not in the "cheatcodes.txt" file.

As a workaround, I disabled all system sounds and saved the config file "knotifyrc" to /porteus/rootcopy/root/.kde4/share/config/knotifyrc

My knotifyrc looks like this:

---------------------------------------
[Misc]
LastConfiguredApp=KDE Arbeitsfläche

[Phonon::AudioOutput]
KNotify_Volume=0

[Sounds]
No sound=true
Use external player=false
Volume=0
------------------------------------------

The other files I also saved were kde.notifyrc and powerdevil.notifyrc - these also contain no references to sounds anymore.

Thus, I have now no sounds playing at startup. I might have replaced all the ogg files in /usr/share/sounds with 0-byte-files aswell.

If you still know a better solution, let me know. I'll wait for final porteus 1.2 in the meantime

volume=0% seems the right solution.

^ You responded to a 3 1/2 yr old thread!!

In fact, I wanted to stay on topic. I did not know that volume cheatcode existed. In my case, I used it to increase the volume on my computer. Old does not mean obsolete.
