I recently installed Gnome 3 in Ubuntu 11.04 on a Lenovo Thinkpad T61p. Since then, my hard volume buttons have stopped working, and my manual volume control via the top-right corner has had no impact on whether or not my computer releases sounds. As a matter of fact, I seem to have no OS-wide volume control whatsoever: it's always on. Going into the Gnome 3 "Sound Settings" makes me feel like there might be drivers missing, as it doesn't recognize any of my hardware, or acknowledge that said hardware exists.

I imagine this has something to do with drivers, but the drivers were working fine until I installed Gnome 3. So I suppose my main question is "Why isn't Gnome 3 listed as the alpha software it is?" with a hefty side of "does anybody know what happened to my sound drivers," and "is there a magic wand I can wave to get them all back?"

You installed a PPA for Gnome 3? That's why you can't install it from the repo's. Everything from a PPA should be thought of as alpha. What directions did you use to install it?

Uh... Too many. Too many different sets of directions, because no one of them got the job done. I have no idea what a PPA is, but I've seen enough instructions that involve them that I tried that without question. At first, it failed. Then, I was told to go into the software center, add the ppa to my software sources (instead of via the command line), and then a whole Gnome 3 section showed up on the left side of my software center, and I just forced it to work from there. It was totally legit. –  Daniel Jun 1 '11 at 4:03
    
If it had been legit, you wouldn't have forced it to work or used so many different sets of instructions. –  wojox Jun 3 '11 at 19:45
    
That last sentence was supposed to be sarcasm. Anyway, my audio is working again... But the question still stands, I guess: does gnome 3 mess with your drivers? –  Daniel Jun 4 '11 at 1:48
    
I suppose you did at least answer the question -- it won't work because I installed shady software. –  Daniel Jun 28 '11 at 14:21
