Weird echo caused by headphone switch?

[Skorobeus]

Ok, bear with me here...

I've got a perfectly functional Teamspeak setup using a normal headset plugged into the mic/speaker jacks on my sound card.

The problem comes in when I plug in the Headphone switch I picked up from Radio Shack. Once this is plugged in, even when only the output cable is hooked up I start echoing everything I receive back to the server.

What totally boggles me is that this happens when NO input device is connected anywhere, I simply have to have this switch plugged into the speaker jack on the sound card, and the echo starts. I know it doesn't make any sense, but I've had this behavior on 3 different computers (all with different sound devices) and 2 different switches.

Please understand (before I get 16 people pointing me to all the other echo posts) that this is *not* the typical echo problem caused by needing to change mixer settings / etc. This is *only* caused by this headphone switch.

Anyone have any thoughts?

Thanks!

I plug in the Headphone switch ? may be it is not ment for use with pc's or like most stuff at radio shack it's junk and not worth the money you spent on it

It's a switch meant specifically for PCs.

It has a jacks for a set of speakers, and a headset and microphone, and plugs into the PC microphone and speaker jacks, and lets you switch between speakers and headsets.

The odd thing is, I *only* experience problems with it when using Teamspeak.

most echos come from the "what you hear " setting in the mixer / sound propertys reconding source being checked , dubble check that another app has not swithced this on ? does this proublem go away if the switch is unpluged and only the headset is pluged in pc ?
