I just got my CF 51 here and I was installing Ubuntu 12.10 on it. Though it seems like the system knows what audio devices are in there (lspci shows them), I dont have any sound.


00:1e.2 Multimedia audio controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Audio Controller (rev 04)

Whatever, when Im trying to connect a headphone jack, I hear sound, but its very, very quiet.

I have no idea what I could do to have it working. Any clues, maybe?

You need the 'loose' (extracted) drivers for "SigmaTel High Definition Audio CODEC" for Windows XP Sp2 - use ndiswrapper (or whatever the equivalent is in Ubuntu) to install them... I'm pretty sure Dell, IBM and a few other brands besides Panasonic use those same exact Sigmatel drivers for several of their laptops - Dell's usually got self-extracting drivers for everything, so try theirs to extract the 'loose' ones. It's hell trying to find them on the Panasonic website, although I finally found them there awhile back for Windows 7 Ultimate. Apparently, Windows and Linux both have an issue recognizing that sound chip correctly, so they both install a generic driver for a different audio chip altogether. Also - at least in Win7 - there's something called "Infineon Trusted Platform Module" that isn't recognized at ALL; not sure about Linux, but if so, the drivers for that thingie are all over the web. Hope this helps you out in some small way :-)

Yep, now I see you posted that Ubuntu 12.10 identifies the audio chip as ""Intel 82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Audio Controller"... that's wrong, it's the Sigmatel one I posted above. Win7 had it listed as STAC '97 something or other lol. – WebShack May 13 '14 at 16:10
Put that into your answer. – guntbert May 13 '14 at 16:31
