Comment 3 for bug 1299322

(2x) Audio Out 1/8" Ports (One compatible with inline mic headset)
(1x) Line In Microphone 1/8" Port (retaskable for 5.1 analog audio output)

how many internal speakers ?

for a 6 channels codec, you will lost the headphone volume control if you want to support 5.1 (Front , rear , center/lfe )
