[pulseaudio-discuss] (alsa-lib)pcm_hw.c: SNDRV_PCM_IOCTL_HW_PARAMS failed (-5)

I've removed "default-sample-format = s24le", now it uses S16_LE 
everywhere, fresh log: http://pastebin.com/aaLvtEUQ

Well, after system restart Mic is not working, while it is available and 
selected in UI.
After single switch to Line and back to Mic it starts working fine.
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: http://pastebin.com/fr0cTUu3
