Mageia forum

Hello everyone,
After changing from 32 to 64 bits Mageia 1 (upgrade PC) no sound from the camera. IN Phonon camera is visible but not accessible, in pulseaudio is not visible. Please help.
lsusb shows Bus 002 Device 002: ID 046d: 0802 Logitech, Inc.. C200 webcam

Can you post the output of lsmod while the cam is plugged in here please, this will identify what driver has loaded, also if you can extract from the output of dmesg the messages that are generated as you plug the cam in to usb.

You should see about 4 to 10 lines from the end of dmesg command after its plugged in

Regards peter

maybe not, but it points out your not alone with this webcam, others are expiriencing probs.

usualy the uvcvideo webcams are excelent and just work, but i cant see any audio interface being loaded in your modules or in the kernel when you plug in the webcam.

Hello, I found the problem does not load the module snd_usb_audio because I do not have it in the system.
My question is how to get the missing module?

its already in the kernel you just have to load it

try

modprobe snd_usb_audio

is it now seen in lsmod

ifso you need to add an entry to your modprobe.conf file

something like alias snd-card-4 snd-usb-audio

regards peter

[root@mageia a]# modprobe snd_usb_audio
FATAL: Module snd_usb_audio not found.
FATAL: Error running install command for snd_usb_audio

sorry no luck!

kernel 2.6.38.8-desktop-10.mga

ok for a min i thought maybe i was wrong where it came from, but im not.

I just switched on my mga2 system and plugged in a logitech pro 5000 thats similar to the C200

it uses the uvcvideo and snd_usb_audio

as soon as i plugged it in the snd_usb_audio module loaded .

it is part of the 3.3.6 desktop 2 kernel.

and its files live down the path

/lib/modules/3.3.6-desktop.2.mga2/kernel/sound/usb/snd-usb-audio.ko.xy

check that that file is in place.

regards peter

The module name contains dashes, not underscores

there must be some aliasing somewhere as they both work, underscores or dashes.

anyway suspect that this prob maybe down to missing /etc/modprobe.d/snd-usb-audio

which should have the install commands for the driver

that comes from the sound-scripts-0.{version).mga1 file, so would expect similar in mga2
