Motherboard CD ROM connector not shown in mixer

[Jeff Sherwin]

Binary package hint: alsa-base

There seems to be no detection of the motherboard CD-ROM connector on my MSI K9A2 motherboard. This issue seems to be the same as in Bug 218906, but is more general and probably belongs here in alsa-base, not alsa-driver.

Ubu 10.04 LTS

apt-cache policy alsa-base yields:
alsa-base:
  Installed: 1.0.22.1+dfsg-0ubuntu3
  Candidate: 1.0.22.1+dfsg-0ubuntu3
  Version table:
 *** 1.0.22.1+dfsg-0ubuntu3 0
        500 http://us.archive.ubuntu.com/ubuntu/ lucid/main Packages

Steps:
Install ubu
Have audio connected to motherboard CD-ROM connector (in my case, tv card with separate audio out)
Open mixer

Expected:
Audio and mixer control

Result:
No audio on CD Channel
No CD slider in mixer

As per Post #3 in Bug 218906, adding the line below to /etc/modprobe.d/alsa-base resolves this issue:

options snd-hda-intel model=3stack-6ch-dig
