Also affects 201303-13027 Dell Inspiron 5535

Verified with 12.04.3 (3.8.0-29) and update (3.8.0-33)
But the audio chips are quite different
00:01.1 Audio device [0403]: Advanced Micro Devices [AMD] nee ATI Device [1002:9902]
00:14.2 Audio device [0403]: Advanced Micro Devices [AMD] Hudson Azalia Controller [1022:780d] (rev 01)

Furthermore, these systems all have a 2-in-1 headphone socket
and this issue did not happen on 201302-12844 Dell Latitude 3330, which equipped with:
00:1b.0 Audio device [0403]: Intel Corporation Panther Point High Definition Audio Controller [8086:1e20] (rev 04)
