question for anyone with some knowledge on the AC97 pinout . . .

I've got an X-Fi card with the pinout for the X-Fi I/O drive, but I'm not willing to spend $80 for their front panel drive (I'm sure y'all understand).

Anyways, I'm planning on doing the mod to wire my front panel wires to the X-Fi with full capability, just wanted to see if the crossover I've figured would look like it should work - just wanting some people to double check me, lol!

Here's the AC97 pinout, taken from Intel.com:

1 2
3 4
5 6
7 8
9 10

1 Mic_In - Front panel microphone input signal (biased when supporting stereo microphone)
2 Aud_GND - Ground used by analog
3 Mic_Bias - Microphone power / additional MIC input for stereo microphone support
4 Aud_GND - Ground used by analog audio circuits
5 FP_Out_R - Right channel audio signal to front panel (headphone drive capable)
6 FP_Return_R - Right channel audio signal return from front panel (when headphones unplugged)
7 AUD_5V - Filtered +5 V used by analog audio circuits
8 Key - No pin
9 FP_Out_L - Left channel audio signal to front panel (headphone drive capable)
10 FR_Return_L - Left channel audio signal return from front panel (when headphones unplugged)

and here's Creative's I/O drive pinout for Audigy/X-Fi (as best I've been able to research online):

1 2 3 4 5 6 7 8 9 10

1 - Analog ground
2 - Left out
3 - Audio backpanel mute (grounded with headphone jack plugged in - I think this is Left Return)
4 - Right out
5 - same as pin 3 (I think this is Right return)
6 - Mic In from front panel
7 - no pin
8 - VREF Mic out (voltage reference for mic)
9 - Mic In mute (ground when mic isn't plugged in, +12V with mic plugged in)
10 - Audio Detect (ground when headphones plugged in, not normally used)

Soooooo . . . I've figured this crossover from my AC97 connector to the X-Fi (I list the AC97 pin numbers in the X-Fi pinout configuration):

2 9 10 5 6 1 8 3 7 4

The only two that I'm not really sure of is pin 7 and 4, but I might have overlooked something - any second opinions?
