AC 97 front audio cables on this mb front audio? msi ms-7548

msi ms-7548

Motherboard Specifications, MSI MS-7548 (Aspen) | HP® Support

this is a cable i have

plugging in for a test wont short the board?
I am interested if you can have front audio and spdiff output sound.

HP says ---> One 9-pin audio header for headphone-out and microphone-in (yellow, Vista capable, requires matching front audio jack module)

also HP says ---> "Supports one S/PDIF digital connection"
the board has an internal and external spdif, so what is HP saying?

Quote:
Integrated Realtek ALC888S Audio
*Integrated audio is not available if a sound card is installed.
Audio CODEC: Realtek ALC888S
High Definition 8 channel audio
Supports one S/PDIF digital connection
shows the external spdif #2 rca jack which I use hooked up to a sony receiver.

An AC97 connection will work in place of an HD Audio connection to the motherboard sound connection. The AC 97 doesn't support some jack sensing that the HD Audio does.

It should work OK to test if you can get front panel audio and S/PDIF at the same time.

I plugged it in and get nothing at all, no sound from it and windows playback and record devices do not show it anywhere.

Did you plug it in correctly? As noted, the only difference between AC97 and HD Audio connection is the AC97 does not have some jack sensing that HD Audio has.

the plug going to the MB?
It is keyed and can go no other way than the way it goes.

Got zilch, as if nothing was plugged in.

Maybe realtek chip just knows something is wrong with it.
HD audio does have a sense pin.

I do have my sound set to digital audio playback, would that be why no sound from the front audio?

Yes. Sound has to be set to "Speakers" to get analog audio (what is needed for front panel).

Ok,
I dont even get a speaker option to enable unless I actually plug the HDTV into the back speaker port.

If this was a true HD audio jack, would it be detected as being able to be enabled?

If you have an HDMI cable connected, the PC's sound card is not used and there is no output. As that is what you wanted to test, at least what I gather from your posts, this confirms that you can't get both.
