Distribution: Ubuntu Dapper Drake, Redhat 3 Hardware Environment: Logitech Fusion USB Mic Software Environment: Vanilla 2.6.16.20, Vanilla 2.6.11 Problem Description: The USB mic for the Logitech Fusion webcam is detected and works using snd_usb_audio. There is however a annoying "loud click" for want of a better description approximately every 5 seconds or so. This happens on all machines/distros (Ubuntu/RedHat 4 and Ubuntu with vanilla source kernel) I've tested with the webcam. The issue must be with the usb_driver; reconfiguring ALSA to resample the USB input has no effect. Having looked around the web I see no other people reporting the issue; I have no errors or interesting debug information. Everything is great bar the regular interrupt. This is possible one of the poorest bug reports ever :-( Steps to reproduce: plug in webcam and record sound.
To be sure, build with CONFIG_SND_DEBUG=y and see whether you get any kernel error messages.
Please reopen this bug if: - it is still present in kernel 2.6.19-rc6 and - you can provide the requested information.
I experience the same clicking noise with my Logitech Quickcam Sphere MP on openSUSE 10.3 and kernel 2.6.22.9. The kernel is compiled with CONFIG_SND_DEBUG=y and the only messages I see in /var/log/messages are: Oct 24 17:10:38 linuxbox kernel: ALSA sound/usb/usbaudio.c:352: frame 0 active: -18 Oct 24 17:27:08 linuxbox kernel: ALSA sound/usb/usbaudio.c:352: frame 0 active: -18 Oct 24 17:27:08 linuxbox kernel: ALSA sound/usb/usbaudio.c:352: frame 0 active: -18 Oct 24 17:28:37 linuxbox kernel: ALSA sound/usb/usbaudio.c:352: frame 0 active: -18 Oct 24 17:41:36 linuxbox kernel: ALSA sound/usb/usbaudio.c:352: frame 0 active: -18 Oct 24 17:43:37 linuxbox kernel: ALSA sound/usb/usbaudio.c:352: frame 0 active: -18 Oct 24 17:53:38 linuxbox kernel: ALSA sound/usb/usbaudio.c:352: frame 0 active: -18 I hope that helps. If I can provide any additional information, just tell me. This bug is really annoying, there is a thread at http://forums.quickcamteam.net/showthread.php?tid=6 about this bug.
Ok, I did a recording session with arecord for some minutes and I see a lot of those messages in dmesg: ALSA sound/usb/usbaudio.c:352: frame 0 active: -18 ALSA sound/usb/usbaudio.c:670: cannot submit urb (err = -45)
Could somebody please reopen this bug? I'm willing to provide all necessary information required to fix this bug.
