Yeah, I frequently switch between speakers and headphones, and I don't think that affects the issue. I agree it could be related to the hardware configuration. I can change the power supply, see if that helps.

Sorry to bump this old thread. Like the previous poster it had been gone for months but then happened again. First time for me with headphones on. Very loud and traumatizing screech. I use Windows 7. Anyone had it happen under Windows 8 yet?

I currently use speakers with this card which are connected to the 2 x RCA ports on the back.

Here's something interesting. The noise went away somehow without me having to reboot. Not sure how. I turned off the speakers and collected driver information. When I turned them on again, there was no noise and the card was working. I ran CPU-Z v1.60 among other programs.

Hi raja,   This just happened again today as I was browsing Windows Explorer and clicked on a folder. I'm adding my details.   Power supply: Seasonic SS-400ET Motherboard: Intel DH67BL BIOS: 5/23/11 CPU: Core i3-2100 Memory (exact model): 2 x Kingston DDR3-1600 KHX1600C9D3B1/4G...

Thanks kiteki. Let me do some more reading and see if any of the ones you mentioned are available in demo rooms locally for listening.

Hi all,   I would like to buy full size cans to go with my Xonar Essence STX soundcard, and I'd really like to hear your thoughts.   About me   I've never been into high end audio and have a hard time connecting with some of the jargon around here. This is my first purchase but I'm...

Yeah I would think so too. Anyone able to measure total system power consumption with and without the card?
