I have made a fresh install of PC-BSD 9 on a [unsupported] Lenovo x200t (tablet) ( http://laptop.bsdgroup.de/freebsd/in...op_mf&mfid=154 ). There is no sound or any indicative errors of why there isn't any sound.

I was able to fix the sound after I found out that sound worked through headphones.

I used ThinkWiki to find what audio chipset/codec is used on the X200t: Intel HD Audio with a CX20561 codec

I found out that this chipset was supported by FreeBSD.

I found a post by Sirvo who had the same chipset on his R400 and fixed it by adding the following lines to /boot/device.hints

Code:

hint.hdac.0.cad0.nid26.config="as=2 seq=0 device=Speaker"
hint.hdac.0.cad0.nid22.config="as=2 seq=15 device=Headphones"
