Description Matt Ford 2006-06-18 06:55:38 UTC
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.

Comment 2 Adrian Bunk 2006-11-17 04:59:10 UTC
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 17:53:38 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)
