alsa control headphone with master [solved]

i have another problem question:
how can i have so the master channel in alsa controls the headphone channel as itis really annoying when i press the volume up/down on my keyboard and it just effects the master channel.

thanks in advanced.

What DE are you running?
In KDE you can right click kmix and select your master volume.
Wouldn't know on any of the other DE's beyond turning the volume to zero on external speakers if you use a desktop system.

I ran into this issue a while back. I gave up and decided to use the PCM control rather than Master. I don't use a DE and was lazy so I just set some keystrokes to execute the following commands:
In ALSA

exec amixer -q sset PCM,0 3%+ unmute
exec amixer -q sset PCM,0 3%- unmute
exec amixer -q sset PCM,0 mute

or in OSS

exec ossmix pcm +3
exec ossmix pcm -- -3

Ok i have found the answer (it took me ages  of searching in gconf-editor but i done it , this is for others having this problem)  :
1. go into terminal and run gconf-editor
2. change ./desktop/gnome/sound/default_mixer_device to "alsamixer"   
3. change ./desktop/gnome/sound/default_mixer_tracks to "headphones" (or your choice)
