[LAU] No audio with Debian Wheezy (+ 3.10 bp kernel) on Intel Haswell processor...

[dafreedm at gmail.com]

Hi,

I'm running stock Debian Wheezy (7.1) --- except for a kernel upgrade
(3.10-0.bpo.2-amd64) from Debian backports --- as well as XFCE, on a
couple different hardware configs.  However, I'm struggling to get
audio to work properly on my new Intel Haswell board.

  (1) On a Thinkpad x220: Audio works great, out of the box

  (2) On a Supermicro X10SLQ (Q87 chipset) with Haswell i4770S: Audio
      doesn't work at all --- no audio at all comes out of standard
      rear headphone jack.  (NOTE: Supermicro website identifies audio
      capabilities as provided by onboard RealTek ALC888S chipset, but
      lspci [below] instead identifies Intel HDA audio, courtesy of
      Haswell.  I worry that this might be an issue.)

Could this be an issue with the kernel, or should I be looking
elsewhere.  I was under the belief that 3.10 (unlike the 3.2 kernel
that shipped with Wheezy) had fairly comprehensive support for Haswell
in general!

Some more information is attached below...

I don't have much experience trouble-shooting audio problems, so I
appreciate any suggestions / pointers.

Thanks!
