I still haven’t figured out why the audio volume & mute keys on my desktop box’s keyboard don’t work, but this process sets ‘em up on my Dell Inspiron E1405 laptop… which I just reloaded with Xubuntu / XFCE 4.6 using more-or-less the procedure described starting there, including saving, blowing away, repartitioning, and restoring the Windows partition.
If the audio mixer icon doesn’t show up on the top XFCE panel, other-click the panel -> Add New Items -> Mixer to get it there.
Then do System Settings -> Keyboard -> Layout. Verify that you’re using the default system keyboard layout, as that’s what I’m doing on the laptop and it works. The desktop, now, that’s another matter; I think having two X sessions confuses it mightily.
Then click the Application Shortcuts tab, click Add, and type in each of these…
- amixer sset Master 10%+
- amixer sset Master 10%-
- amixer sset Master toggle
For each command, click OK after typing. You’ll get another pop-up, at which point you press the corresponding volume / mute key.
Note that the Master keyword is case-sensitive and may be something entirely different on your box. Use amixer to find out what you should be typing, thusly:
amixer Simple mixer control 'Master',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 27 [87%] [-6.00dB] [on] Front Right: Playback 27 [87%] [-6.00dB] [on] Simple mixer control 'PCM',0 Capabilities: pvolume Playback channels: Front Left - Front Right Limits: Playback 0 - 255 Mono: Front Left: Playback 245 [96%] [-2.00dB] Front Right: Playback 245 [96%] [-2.00dB] ... snippage ...
Shazam: audio control should then Just Work…
The irony of having to futz around that much before having something Just Work is not lost on me. Really.
