Hey Y'all,
This morning my wife complained that she had no sound when she was logged on to my machine. I logged on to her account and brought up System/Preferences/Sound to see if she had inadvertently selected some other sound output device. Hey, it happens. There was no sound hardware detected. I have a USB microphone and an integrated on board sound card. Neither of these sound devices were available on the Hardware, Input, or Output tabs.
I have access to all these devices when I log on as myself.
This system has been running smoothly since I installed CentOS 6.1 all those many years ago when that was the current point release. Now that 6.6 is out I'm seeing issues with video, fixed already, sound, not fixed already, and my web cam which I have yet to ask for help with. I'm not saying this sound problem has anything to do with 6.6.
Does anyone have any idea where I can start looking to figure out what's going on with my wife's sound hardware detection?
First thing I would check is that other users are not logged in when user in question logs in. (It may be that only one of users at a time can access some of the devices - I'm on the road so have no way to check...)
