Hello,
I have USB webcam with integrated USB microphone. Microphone does not working correctly because kernel module snd-usb-audio set wrong bitrate.
Problem appered after this commit: http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.39.y.git;a=commit...
When I reverted patch in above commit microphone works properly. This commit set bitrate to 8000Hz for 041e:4068 but my webcam (propably) produce 16000Hz. So what to do with my webcam? It needs to revert above patch!
Here is output from lsusb of my webcam: Bus 002 Device 003: ID 041e:4068 Creative Technology, Ltd Live! Cam Notebook [VF0470] Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.10 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 8 idVendor 0x041e Creative Technology, Ltd idProduct 0x4068 Live! Cam Notebook [VF0470] bcdDevice 1.00 iManufacturer 1 iProduct 2 iSerial 0 bNumConfigurations 1
Could you give the lsusb -v output?
Arseniy, also check whether the current code is really OK?
thanks,
Takashi
