I have got my audio card and alsamixer working on my Gentoo installation, as I'm too bored to visit that program all the time I need to make a subtle audio adjustment I'm looking forward to doing this with a volume control on my Xfce panel and/or the hardware audio keys just like I'm used to...

So... How do I install a volume control in Xfce and get support for my hardawre buttons?

I tried installing xfce4-mixer but I only seem to have an entry in Applications > Multimedia called Mixer which upon launching gives the following error:

GStreamer was unable to detect any sound devices. Some sound system specific GStreamer packages may be missing. It may also be a permissions problem.

Although I do have audio working...

Just do:

emerge xfce-extra/xfce4-volumed

If you have a volume knob or volume keys it should just work. you might also want:

emerge xfce-extra/xfce4-notifyd

To get a nice popup when you change volumes.

@nodisc: I get the error Skipping unavailable plugin 'alsasink' there. – Tom Wijsman Jun 22 '11 at 19:20
@nodisc: emerge gnome-media gst-plugins-alsa did the job. – Tom Wijsman Jun 22 '11 at 19:23

You are not asking the right question. Its not "in Gentoo" its in xfce or

You can read a general guide here: xfce special key bindings

Now, tell me that you're talking about laptop buttons and not the ones on your keyboard and ill link you to an acpi guide. As to the second part of your question Id recommend you add your user to the audio group, log out and then back in.

Keith disproves your statement, an emerge is handier than doing everything manually... – Tom Wijsman Jun 17 '11 at 10:24
lol install ubuntu. If the dude above fails to find a package, then wtf can I do.. – Ярослав Рахматуллин Jun 17 '11 at 11:49
What can Ubuntu do for me? Why wouldn't a package be available? Why not follow the KISS principle? – Tom Wijsman Jun 17 '11 at 12:51
Wow, that's incredibly rude. I apologize. – Ярослав Рахматуллин Mar 16 '13 at 6:32
