is the following patch based on real hardware ?

Thu, 17 Nov 2005 14:31:34 +0000 (15:31 +0100) Add AD1988 codec support to hda-codec driver.

Thu, 24 Nov 2005 15:17:20 +0000 (16:17 +0100)] Fixed the swapped surround/CLFE on 3stack mode of AD1988.
hda-emu codecs/ad1988a -m "3stack" route -a 0x15
Out[0a] -x Sel[31] -- Mix[2c] -> Pin[15] Out[04] -> Sel[31] -- Mix[2c] -> Pin[15]
route -a 0x17
Out[04] -> Sel[32] -- Mix[26] -> Pin[17] Out[05] -x Sel[32] -- Mix[26] -> Pin[17]
In simple word,
surround51 does not work with 3stack model since the above route in hda-emu indicate that blue jack and pink jack are connected to DAC1 (node 0x4)
Oh, care to create a fix patch? :)
thanks,
Takashi

SergeyR replied that the patch work with his Asus M2N

However does the following patch has any side effect for motherboard with 3 audio jacks ?
seem the blue jack and pink jack are retasked to wrong output channels

ALSA: hda - Fix surround/CLFE headphone and speaker pins order
When 5.1 or more headphone or speaker pins are provided, the parser still takes as is without fixing the order of channel mapping, which leads in the unexpected strange channel order by surround outputs.
This patch fixes the issue by applying the same fix-up not only to line_out_pins[] but also hp_pins[] and speaker_pins[].
