[Analog Devices AD1984A] Recording problem : loosing microphone after using applications

[aly]

1)
~$ lsb_release -rd
Description: Ubuntu 10.04.1 LTS
Release: 10.04
(amd64) language = French

2) ?

3) i expect my microphone to work all time when i need

4) the microphone works properly for a while, and stops unexpectedly after a while (usually after starting another app)
For instance I can speak with somebody on skype for 10 minutes and suddenly the mic stops
there is no way to start it again, unless i reboot the machine

I have exactly the same problem as described in this post :

I have reassigned this issue to Linux kernel package for you (maybe an alsa-driver issue)
