Re: [Linphone-users] Laptop internal speakers now always on

[Simon Morlat]

Hello,

I'm sorry for the inconveniance of that behaviour.
Normally (it does like this on my laptop) we can switch speaker volume to 0 by 
setting the "Master" level of your sound mixer to 0.
The level of the headphones is controlled by the "headphone" slider.
My preferred mixer is kmix from kde, if you don't like kde, you can use also 
alsamixer (it works in console mode).
alsamixer only works if you are using alsa drivers (which is usually the 
default on recent linux distribs).
It's the best mixer programs in terms of functionnality: it implements all the 
controls of the device.
