Windows 7: No Audio Output via Front and Rear Jacks

12 Jun 2011   #1

Windows 7 Home Premium 64 bit
No Audio Output via Front and Rear Jacks

Hey guys,

I installed the Hyper 212+ this weekend, but after installation, the audio stopped working. Thinking that this was a hardware issue, I went back and replugged some of the cables back into the mobo to make sure they were securely in there. No luck.

My setup (other specs in profile):
- Phenom x4 955
- Radeon 5850
- ASRock 870 Extreme3

Sound appears to work (green bars move, Windows doesn't detect any problems), but there's no output. Here's what the Sound control panel looks like:

(Note that I do indeed have speakers/headphones plugged in.)

I also went into the Realtek HD Audio Manager to see what's going on and it lists only Digital Output. None of the analog jacks appear to be active in the Manager window, unless I disable front panel jack audio detection. Here's what it looks like with front panel detection enabled:

And with front detection disabled:

I've done a couple of things so far:
- Tried headphones and speakers in front and rear audio jacks.
- Even tried microphone in front mic-in jack - didn't work. A USB (connected to front panel) mic did work, however.
- Restored BIOS to factory defaults.
- Disabled/re-enabled onboard audio in BIOS.
- Installed/uninstalled/reinstalled audio and video drivers.

I've also messed around with the Realtek HD Audio Manager itself:
- I disabled front panel jack audio detection. This added two additional in/ouputs: Speakers and FrontMic. Neither work.
- Changed default device to speakers. Nada.
- Tried enabling "Make front and rear output devices playback two different audio streams simultaneously."

I even looked at the registry after checking out the Changing Jacks stickied thread in this forum, but not all the jacks are listed (?):

So anyway, I have no clue what the problem is other than maybe it's outputting the sound digitally via SDPIF for some reason and I can't figure out how to get Windows/Realtek to detect the analog output jacks instead.

Help anyone?

flaergr, welcome to the Seven Forums.

Might help if you set the Speakers as the default device instead of the digital one. Unless you're specifically using the optical/digital connections on the back, both the regular and front panel jacks are analogue.

Yeah, I've tried setting the Speakers to the default device (which only became available after disabling the front panel detection), but there was no change - still no audio.

My hypothesis is that Windows is only outputting digitally to SPDIF and I can't force it (for whatever reason) to output to the analog jacks.

When you re-installed the Realtek driver did you use the latest,

Latest Realtek HD Audio Driver Version

or the somewhat antiquated version on the motherboard disk or from Asrock (and I thought Asus was bad for providing updated drivers)?
