USB microphone disappears when Skype call starts and reappears when it ends

[Shahar Or]

Dear friends,

I've a USB microphone, which just when a Skype call begins, it just disappears from the input selection. When the Skype call ends, it returns.

Thanks,
Shahar

Either this is inconsistent or has been fixed. I've tested and not experienced it any more.

Thanks,
Shahar
