alsa-info ouput with not working microphone configuration (2.6.41 kernel)

This is alsa-info from Fedora 15 with all updates as of 2011-11-26 booted with  2.6.41.1-1.fc15 kernel.

In this case on Samsung N110 the microphone record just noise.

For references here is a diff u output that compares working and not-working configs:

Let me know if alsa-info output for Fedora 16 Live CD image is necessary - when I tried it I got the same behavior as with 2.6.41 kernel on Fedora 15. That is, the microphone recorded just static noise.

I confirm this bug. I have the same problem on F15 (latest updates) and F16 live, both x86_64, using a Pleomax webcam, which I think is a Samsung brand.

When I record sounds (arecord -d 5 -D "plughw:4,0" -f S16_LE test-mic.wav) from the webcam, the green LED is on and sound is recorded with kernels up to 2.6.38.6-26.rc1.fc15.x86_64. Doing the same thing with kernels from 2.6.40.6-0.fc15.x86_64 and up, there's no LED and no sound recorded. Well, something is recorded but it's just a big 'thump' in the beginning continuing with some slight static noise.

Pleomax webcam device:
Bus 001 Device 002: ID 04f2:a13b Chicony Electronics Co., Ltd

Please let me know if you need more information about my hardware or anything else.

Thanks

I didn't test kernel-3.3.0-4.fc16 but I did test the current F16 kernel (3.3.1-3.fc16.x86_64) and unfortunately the behavior is the same as before.

Here are the tests I did:

For a different need (music recording), I've built a minimal RT kernel from 3.2.15 for my F16 installation. I found out that with this kernel the sound from my webcam works!

So this seems now to be a Fedora distribution issue. At the moment I don't have much more information to provide about this but please let me know if there's any information about my kernel configuration that could be of any interest.

In F16 with all the updates and in in F17 the microphone works.
