Comment 20 for bug 1195377

> Takashi Iwai had me test this patch, and it fixes Stereo 2.0 output / input enough that it works for me. Surround 5.1 is not working.

it is because the driver put two headphone pins at spec->hp and multi_out at same time

Each [audio output] has volume control, after the driver assign [audio output] to speaker and two headphone nodes, there is no [audio output] left for the "Front", "Surround", "Center" and "LFE" playback volume

either

speaker, headphone, headphone

or

speaker, front, surround, center and lfe (no headphone playback volume as two headphone had been retasked as line out jacks
