Description Rodd Clarkson 2005-09-18 05:20:35 UTC

Description of problem:

I have a Dell 9300 which comes with a sub-woofer.

lspci shows that the sound card is a:

00:1e.2 Multimedia audio controller: Intel Corporation 82801FB/FBM/FR/FW/FRW
(ICH6 Family) AC'97 Audio Controller (rev 03)

When I set up the keyboard shortcuts to control the volume and mute it only
affects the main volume, and not the sub-woofer volume.

The main speakers are listing in Volume Manager as Master, with the sub-woofer
controlled by Master Mono.  Unfortunately, the keyboard short cut preferences
only affect Master (and not Master Mono). As a result, the main speakers are
turned down, but the sub-woofer still makes noise.

There needs to be either an inclusion of master mono in what's affected by the
keyboard shortcuts, or some way to lock master mono and master so that work in
unison.  That later would be the better option.

How did you set up the keyboard shortcuts to control the volume? In other words,
what commands are used for the volume control?

Comment 2 Rodd Clarkson 2005-09-19 09:11:27 UTC

To set up keyboard shortcuts I do the following:

1. Select Desktop > Preferences > Keyboard Shortcuts
2. In the Keyboard Shortcuts dialog, under 'Sound' there are the following options:
    Volume mute
    Volume down
    Volume up
    [Other options to do with playback.]

Click on one of the volume options (which then waits for the next keystroke) and
press the appropriate key.  In my case I have some multimedia keys on the front
of the laptop that I use for this.

The key values are as follows:

    Volume mute : 0xa0
    Volume down : 0xae
    Volume up   : 0xb0

okay, reassigning to control-center...

I'm not convinced that this is a dupe.

If I open up the Volume Control I see two Master Volume Controls.  One is called
Master, the other is called Master Mono.  Master controls the stereo sound
volume you would typically find in a laptop and has two sliding bars that are
locked, Master Mono controls the sub-woofer volume and has a single sliding bar.

If I click on the volume up and volume down bottoms on my laptop, then the
Master volume control changes, but the Master Mono volume remains the same.

If I click the mute button, then the Master control is toggled between mute and
normal, but the Master Mono Volume remains unchanged.

It appears that in my case the buttons are working, but they just aren't acting
on all the Master channels.

It is my opinion that clicking these buttons should change all the master volume
controls, not just one set.
