intel_hda_audio, sometime works, sometime doesn't

Hi all, I think mepis has same problems loading audio drivers.

This is my audio card:
Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 04)

Sametimes,just after the boot it's not workin. If I click on kmix I see only USB2.0 Video microphone and anything else.
I look if the drivers of the audio card ad loaded and it seems they are (see below).
The only thing I can do is reboot the system.

I worte samething similar times ago for anather audio card (external)

I also have anather strange issue:
I can't play .mp3 and .flac files with noautun. I'm sure I was able to do it because I'm using it like alarm clock and it was playing mp3. I don't remembre when, it stoped to play same kind of file.
The .wav and .ogg are reproduced correctly.
Amarok doesn't have any problems.

Do you have any idea?
May you update alsa driver to the lastest stable version?
