My onboard sound card captures (quite loud) white noise when I connect my headset to my front I/O panel. Everything works fine if I use the ports in the back. This is new. A while ago (on Win 7 I believe), I used to have the same problem with the onboard card (when using the front panel) that I have with 2 other cards (ASUS Xonar DG, Soudblaster X-Fi XtremeGamer): With either of my sound cards, no matter where or whether I connect any audio hardware, the "microphone" always captures any sound I hear, in addition to what the microphone picks up (when it's connected).
- issue persists regardless of what audio hardware is connected where or whether any is connected at all (except for the new onboard white noise issue mentioned above)
- issue persists among two independent installations of Windows (first 7, then 8; clean reinstall, no upgrade)
- issue persists across two PC cases (including front panels and wiring)
- issue persists across 3 sound cards total (onboard, x-fi, xonar dg)
- stereo mix / "What U Hear" disabled in recording settings
- "listen to this device" disabled for microphone in recording settings
- "Allow applications to take exclusive control of this device" (microphone) on/off no change
- Skype "automatically adjust microphone settings" shenanigans turned off
- issue persists with microphone boost turned on or off, but is more noticeable with boost turned on (obviously)
- "Speakers" is the only enabled output device
- for the x-fi and the xonar dg, "microphone" does not show as "unplugged" when no device is connected and still echoes whatever I hear
I don't understand how this can happen. If someone here can help I'd be extremely grateful. Otherwise I'll probably just buy a USB headset and be done with it. This has been going on for months and doesn't seem worth my time anymore.
