I prefer from far the first solution (switching to next sound card if
one) :-) .
I don't succeed in using this :
/* Save this text as m.src and then run
eet -e modules.mixer.cfg config m.src 1
Then copy modules.mixer.cfg to .e/e/config/<profile>/
And then restart e with ctrl-alt-end */
group "Mixer_Module_Config" struct {
group "gadgets" hash {
key "mixer.1";
group "Mixer_Gadget_Config" struct {
value "lock_sliders" int: 1;
value "show_locked" int: 0;
value "keybindings_popup" int: 0;
value "card" string: "hw:0";
value "channel_name" string: "Master";
}
}
group "gadgets" hash {
key "mixer.0";
group "Mixer_Gadget_Config" struct {
value "lock_sliders" int: 1;
value "show_locked" int: 0;
value "keybindings_popup" int: 1;
value "card" string: "hw:1";
value "channel_name" string: "PCM";
}
}
value "version" int: 3;
value "default_gc_id" string: "mixer.0";
value "desktop_notification" int: 0;
}
Icon still refuses to show up on shelf.
