I'm new to programming this thing; can someone point me towards documentation on how I can change the volume and mute setting from either the command line or Python please? I've hunted through the wiki and googled without any luck.

From the commandline:

Code:

gconftool -t int -s /apps/osso/sound/master_volume -- -100

should mute,

Code:

gconftool -t int -s /apps/osso/sound/master_volume -- (level)

should unmute. In practice, you might want to first get the value of /apps/osso/sound/master_volume, then set it to the opposite of that. The same method could be used to unmute.

Since this is using gconf, writing it in python would be a simple matter of figuring out how to use gconf in python

Can't write sample code right now, but I can try later today if you need it.

Theoretically:

Code:

        from gnome import gconf
        gconf_client = gconf.client_get_default ()
        gconf_client.set_int("/apps/osso/sound/master_volume", -gconf_client.get_int("/apps/osso/sound/master_volume"))

In practice it does not work for me. It sets /apps/osso/sound/master_volume to 0.

The gconftool solution works great for me. I gotta read up on that. Thanks!
