[SOLVED] KDE Mixer Sound on 100% after Reboot

Hi all,

Litte problem making me nuts. Can be very unpleasant for the ears. Every time I reboot, my KDE Mixer Playback Device Volumes are all back to 100%. This does not happen upon log out and in again, only after a reboot.

I tried to toggle the 'Restore volumes on login' setting in the KMix Configure Panel under Start, but that did not change anything.

Anyone having some idea how to find a solution?

Thanks

Its a while since i did this, so please use your initiative to locate the detail

use alsamixer a text mode program to setup the initial defaults, then save its config so that
on boot the settings are at a reasonable level.

im not sure its kde itself at fault.

I haven't installed Mageia 6 KDE, but have spent a bunch of time running it from the live DVD. Which is to say, I don't know if this problem goes away after installation.

The problem is that, when KDE plays system sounds (such as the system bell), the volume level spikes to 100%, no matter what it was set at before.

One solution involves editing /etc/pulse/daemon.conf, and uncommenting the "flat-volumes = yes" value (i.e. remove the ";" in front of it) and changing "yes" to "no", so that the entry reads:

flat-volumes = no

Then log out and log back in. That seems to do the trick.

Founde this on the Errata which may help:
Plasma 5 / KDE Applications
The volume of the sound changes suddenly to 100% during a Plasma session

This is because PulseAudio uses flat volumes by default, instead of relative volumes, relative to an absolute master volume (mga#19377). If this is found to be inconvenient, relative volumes can be enabled by disabling flat volumes in the PulseAudio daemon's configuration file:

edit etc/pulse/daemon.conf
change

;flat-volumes = yes

To

flat-volumes = no

then restart PulseAudio by executing

pulseaudio -k
pulseaudio --start

Yes, that definitely works.

Thanks for the solution. Seems to work for me too! :D (I just had to log out and in again, stopping and starting again pulseaudio was giving me an error.)
Will mark it as solved.
