i am a fun of and running opensuse 12.2 32bit on a thinkpad T400. it has dedicated volume buttons close to the keyboard. when i first installed, right at the top of my screen, there was an audio application which after awhile disappeared. so i am unable to use the keys… secondly, my internal video device (camera) works well during daylight but doesnt work in the night… thirdly, my internal mic doesnt work either.
That info provides a starting point. Have a look at this Multimedia subforum sticky information. It will tell you how to collect and present further tech detail needed to identify the problem. There is also a link there to a Wiki guide on Audio Troubleshooting in openSUSE.
That’s the problem. It means the DE (gnome) and/or the sound server (PulseAudio) is not aware of the sound device and its configuration.
Other–> Volume, mic, speaker, mic boost etc are all at 100
play test sound; i hear the sound
Good. The sound chip works, and also the basic sound driver module snd-hda-intel (provided by ALSA). BTW, I have the same audio device and driver.
start sequencer, i click ok but nothing happens
Doesn’t matter, since most laptop audio chips don’t have one, and the function will be done by software.
pulseaudio configuration is enabled
That’s good, and it should be enabled by default. But it’s not working!
One thing to try next. Check if the package “pavucontrol” is installed (terminal command: zypper se pavucontrol, or use YaST). If not, install it and run it. You can go through it’s settings to see if it enables your device. It’s a fully-featured PulseAudio Volume controller. It has mysteriously helped a few users in your situation, where Gnome or KDE hasn’t enabled sound properly.
My suggestion is to open a new thread for the issue … persons interested in webcams, and whom might be able to help you, might not think to or be interested in checking out a thread simply entitled along the likes of “thinkpad t400 issues” lol!
And then, if you have a solution, you could come back to this thread (for the benefit of other t400 users) and say “found a solution [link to other thread] for this problem”
I’d also suggest that (in your, currently theoretical, new, and well titled in relation to the problem, thread) you provide as descriptive info as possible, such as:
model type (“lsusb -v”),
driver (if you know, if not, the appropriate type should be able to be gleaned from the USB subystem ID given by the former cmd)
what “runs well during day time but blacks out during night time” means … its pretty vague … you haven’t described the ambient conditions, what apps you are using etc etc etc.
