Comment 12 for bug 290549

SRU Justification:

Impact: Some Dell models incorrectly intialise sound, leading to non-functional headphone support.

Fix Description: Add a machine specific Quirk to select the correct audio settings.

Patch: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-intrepid.git;a=commit;h=1e78af48934d3a7ae4025cd04da09dbfc8a2ad56

Risks: this is a machine model specific quirk, is already in the upstream kernel, and also in Jaunty.

TEST CASE: Boot Intrepid on affected machine and check sound on the headphone socket (socket nearest the front of the machine).
