[Bug 1033146] Re: Microsoft LifeCam HD-3000 with Ubuntu 12.04: webcam light blinks, and freezes with guvcview
Hi, This is a development message which shouldn't be reported that often. It's not the root cause of issues seen with the LifeCam... just misleading. I investigated the issue down to the kernel driver with additional traces. The set frequency operation at 48 khz goes through just fine, but the validation get frequency request performed right after isn't supported by the lifecam. The error code returned on that operation isn't 0, and in that case the driver issues that message. However, having a non-success for this operation is perfectly fine. For more information, refer to USB Audio specification, when the adapter doesn't support such Get operation. See page 67 in http://www.usb.org/developers/docs/devclass_docs/audio10.pdf If the addressed Control or Entity does not support readout of a certain attribute, the control pipe must indicate a stall when an attempt is made to read that attribute. So, IMHO, the warning that we see is a development warning, not a bug per se. The status code should be checked and the driver should remain silent UNLESS some really unexpected status code comes up. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1033146 Title: Microsoft LifeCam HD-3000 with Ubuntu 12.04: webcam light blinks, and freezes with guvcview To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/guvcview/+bug/1033146/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1033146] Re: Microsoft LifeCam HD-3000 with Ubuntu 12.04: webcam light blinks, and freezes with guvcview
This is a problem that affects programs that don't use the video or Flash. If I I try to set the webcam as the source of sound in audacity, there is a delay of a count of 20 or so before it acknowledges that it is set up, and another long delay of many seconds before anything actually is recorded when I press record. So this isn't a guvcview bug - although that's where I came across it too - it's a problem with the webcam / snd-usb-audio. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1033146 Title: Microsoft LifeCam HD-3000 with Ubuntu 12.04: webcam light blinks, and freezes with guvcview To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/guvcview/+bug/1033146/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Well disabling snd-usb-audio is not really a solution, one needs the mic to work when on a video call.

SOLVED: all my troubles were caused by the latest built-in chrome flash player (pepper version 11.3.31.232).

Temporary solution: it seems that the problem is caused from snd-usb-audio module: this module is loaded because LifeCam is an double USB device, audio and video. Putting the line blacklist snd-usb-audio into /etc/modprobe.d/blacklist.conf solves problem with video but stops every other usb audio device. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1033146 Title: Microsoft LifeCam HD-3000 with Ubuntu 12.04: webcam light blinks, and freezes with guvcview To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/guvcview/+bug/1033146/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
