I can reproduce this bug. (Thinkpad X200s with Fedora 16 isntalled through anaconda upgrade from DVD. x86_64 architecture.)
Comment 3 Erik Bartoš 2011-10-16 18:13:00 UTC 
1. Run "alsamixer" in console
3. "Segmentation fault"

Fresh Fedora 16 Beta installation through preupgrade.
Comment 4 Erik Bartoš 2011-10-20 08:53:57 UTC 
More comments:

1. I have multi-user installation of Fedora 16 Beta. So booting is into console. In console works sound and also "alsamixer" is running.
2. After logging into X by "startx", the "alsamixer" is not running, showing segmentation fault, also "aplay -l" shows no sound card device.

I think there are some permission problems, but now I cann't  define them.
Comment 5 Erik Bartoš 2011-10-21 17:04:17 UTC 
Solved!
I've reinstall ConsoleKit stuff, plus new updates of F16. Sound is working in console and gnome-shell.
Comment 6 Martin Kho 2011-10-21 17:30:05 UTC 
Hi,

Tried reinstalling ConsoleKit[-libs,-x11], with no change. For me, alsamixer still segfaults. Btw. I'm running KDE with all latest updates installed and have never had any problems with sound.

@Erik: What new updates made alsamixer stop crashing?

Comment 7 Martin Kho 2011-10-21 18:43:57 UTC 
Hi,

alsamixer runs at the console (ALT+CRL-F[2,3,4,...]) okay, the issue appears only when in graphics mode. In Konsole (KDE, 4.7.2) or Gnome Terminal (3.2.1) alsamixer segfault. My graphics card is a NV4B and I use the nouveau driver.

Hope this helps,

Martin Kho
Comment 8 Erik Bartoš 2011-10-22 13:36:34 UTC 
Hard to say which updates, I'm updating daily a lot of packages.

The correct command for alsamixer is "alsamixer -c 0", without the options is "segmentation fault" also in my case. But sound is working...

Btw, I've also found out, that my installation (Fedora 16 beta, Nvidia driver, gnome-shell) is slow in comparison to previous version. I'm trying to find out why.
