Connecting Front Audio Panels

[TechnoBabble]

I have 2 new cases with front audio panels. Both motherboards have the same Front Panel Audio Headers (Intel compliant). The pins are as follows:

1 AUD_MIC Front panel microphone input signal
2 AUD_GND Ground used by analog audio circuits
3 AUD_MIC_BIAS Microphone power
4 AUD_VCC Filtered +5V used by analog audio circuits
5 AUD_FPOUT_R Right channel audio signal to front panel
6 AUD_RET_R Right channel audio signal return from front panel
7 HP_ON Reserved for future use to control headphone amplifier
8 KEY No pin
9 AUD_FPOUT_L Left channel audio signal to front panel
10 AUD_RET_R Left channel audio signal return from front panel

Case No 1 has connectors labelled:
GND
MIC IN R
MIC IN L
GND
R-OUT
L-OUT

Case No 2 has connectors labelled:
GND
MIC-VCC
MIC-DATA
EAR-R
EAR-R
EAR-L
EAR-L
NOTE: The EAR-R connectors are attached to a single wire as are the EAR-L connectors.

I would be eternally grateful to anyone who can work out which connectors go on which pins.

This is MY best guess:

Case No 1 has connectors labelled:
GND to 2 AUD_GND Ground used by analog audio circuits
MIC IN R to 1 AUD_MIC Front panel microphone input signal
MIC IN L
GND
R-OUT to 5 AUD_FPOUT_R Right channel audio signal to front panel
L-OUT to 9 AUD_FPOUT_L Left channel audio signal to front panel

Case No 2 has connectors labelled:
GND to 2 AUD_GND Ground used by analog audio circuits
MIC-VCC
MIC-DATA to 1 AUD_MIC Front panel microphone input signal
EAR-R to 5 AUD_FPOUT_R Right channel audio signal to front panel
EAR-R
EAR-L to 9 AUD_FPOUT_L Left channel audio signal to front panel
EAR-L
