> After single switch to Line and back to Mic it starts working fine.<br>
> I wasn't able to reproduce it twice during working session, so, here is verbose log of the first start right after system restart where Mic was initially selected but didn't work, and started working after switching to Line and back: <a href="http://pastebin.com/fr0cTUu3">http://pastebin.com/fr0cTUu3</a></p>

You may need add pa_log_info() to element_set_volume() , element_set_switch() and element_set_option() to log alsa mixer element and values (mic capture volume, mic capture switch and pcm capture source) set by pulseaudio</p>
