Title:
volume keys on different devices can't set different volume sliders
Status in Gnome Settings Daemon:
Fix Released
Status in “gnome-settings-daemon” package in Ubuntu:
Fix Released
Bug description:
Binary package hint: gnome-settings-daemon
Hello! I'm running up-to-date Jaunty. (Although I'm pretty sure this
happens with all Ubuntu releases, I haven't tried it yet.)
I have a desktop computer that has an integrated sound card, and I
bought recently a USB-connected wireless headset from Logitech. My
keyboard has separate keys for volume control (volume up/down and
mute) in a corner, and the headset has two buttons on one of the
headphones for the same purpose. As far as I can tell, the headset
registers itself as a Human Interface Device and simply sends key-
presses like a USB keyboard would.
First of all, everything works more or less as expected: I can use
Pulseaudio to route sound from any application to either my speakers
or my headset* (or both), and pavucontrol can individually control the
volume** of the sound card and the headset.
(*: except that Skype doesn't seem to work at all with Pulseaudio,
which is sort of why I bought the headset, but that's another bug and
it has nothing to do with what I'm reporting here.)
(**: except that AFAIK it doesn't control the hardware volume of the
sound card, it only scales the samples sent to it. Which sucks, but
it's a different bug and reported elsewhere.)
Also, both the volume keys on my keyboard and the buttons on the
headset work. I have XF86Audio{Raise|Lower}Volume set as "Shortcuts"
for volume up/down in the Keyboard Shortcuts applet, and they both
work. The problem is that they both work on the same volume control;
as far as I know that's the "master volume slider" that is picked
through one of the settings applets (I can't find it right now; I
think something changed recently in Ubuntu's settings applets,
unrelated to this).
I'd like a way to have either pair of volume buttons control a
different slider. Ideally, I'd like the keyboard to control the
_hardware_ volume control of my sound card (but software's OK) and the
buttons on the headset to control the headset's volume (I'm not sure
if that one has a hardware volume slider, but that's less important).
It's not absolutely necessary to have a very pretty interface* for all
this, I can handle a few config files, but I'm not aware of any
reasonable way of getting the same keysym from two different input
devices to do different things.**
(*: Although, if it were technically doable, my particular case could
be very intuitively handled by a single check-box and a bit of logic:
if there's any USB device that exposes both Audio and HID interfaces,
watch them. Intercept any volume/mute key presses from their HID part
and use them to control the Audio part's volume. Also add a single
check-box for them that says "X controls master volume control" and
leave it unchecked by default, in the eventuality that someone doesn't
want this.)
(**: Actually, I'd like to be able to do this in general. For
instance, I'd like to have two keyboards with two different layouts
instead of switching layouts using the applet.)
Let me know if you need any hardware/other information for this. I'll
attach this to gnome-settings-daemon because I think this actually
controls the volume when the keys are pressed. (By the way, I
volunteer to implement whatever changes are needed, if a little
mentoring is offered.)
