I would appreciate some help figuring out how to plug in my front panel audio connections. Here are links to the manuals for the case and the motherboard.

http://us1.msi.com.tw/files/downloads/mnu_exe/E7350v1.0.zip
http://www.coolermaster-usa.com/Downloa...ation/Elite%20330-331-M_RC-330-331.pdf

The manual for the case doesn't label the wires the same as the labels on the product. They are actually labeled:

Yellow - MIC-IN
Red - MICPOWER
Black - GROUND
Brown - R-OUT
Brown - R-OUT
Orange - L-OUT
Orange - L-OUT

Both browns are connected to one wire, much like molex power connectors plug into a hard drive and split off for another connector. The oranges are the same.

As you look at the diagram of the motherboard's front panel audio connections on page 2-17 of the pdf inside the zip file, it does not have a plug for MICPOWER, but has both MIC_L and MIC_R, where the case only has MIC-IN and MICPOWER.

I won't say anything more as I'll probably just confuse you. If you would be kind enough to look at the manuals and let me know what I should do, I would appreciate it.

Thanks.

The MSI board follows Intel Front Panel I/O Connectivity Design Guide (Section 2.3, pp. 19 - 25) in formfactors.org (maintained by Intel) that is compatible with AC'97 front panel audio. So
  1. Pin 1 - PORT 1L (MIC_L) -MIC (Front panel microphone input signal)
  2. Pin 2 - GND - AUD_GND (Ground)
  3. Pin 3 - PORT 1R (MIC_R) - MIC_BIAS (Microphone power)
  4. Pin 4 - PRESENCE# - AUD_GND (usually no connection)
  5. Pin 5 - PORT 2R - FP_OUT_R (Right channel audio signal to front panel)
  6. Pin 6 - SENSE1_RETURN - FP_RETURN_R (Right channel audio signal return from front panel)
  7. Pin 7 - SENSE_SEND - AUD_5V (usually no connection)
  8. Pin 8 - KEY - KEY (No pin)
  9. Pin 9 - PORT 2L - FP_OUT_L (Left channel audio signal to front panel)
  10. Pin 10 - SENSE2_RETURN - FP_RETURN_L (Left channel audio signal return from front panel)
In Cooler Master's pdf,
  • Pin 5 = PORT 2R = FP_OUT_R = Brown/Brown-FPOUT-R
  • Pin 6 = SENSE1_RETURN = FP_RETURN_R = Brown-RET-R
  • Pin 9 = PORT 2L = FP_OUT_L = Orange/Orange-FPOUT-L
  • Pin 10 = SENSE2_RETURN = FP_RETURN_L = Orange-RET-L
