Speakers wont turn off when headphones are plugged in

saltedm8 · 21 Feb 2013

I am on windows 7 64bit, I have listed in my speaker system 4 different devices

this is the order they are listed and their status also

Sharp HDMI - Disabled (unplugged) - I have to manually enable it when I want to plug my laptop to my tv

Speakers - Ready - Default Device

Headphones - Disabled, unplugged

Headset Earphones - Default Device when plugged in (otherwise not visable on list)

Here is the issue

If I were to plug in the Earphones Headset Earphones without the Sharp HDMI being disabled (but still unplugged) my laptop for some reason selects both Headset Earphones and Speakers, some sound comes out the speakers, others the Headset Earphone

If I disble the Sharp HDMI then when I plug the Headset Earphones in it swaps as it should to the Headset Earphones making them the default device and only the Headset Earphones work so when I pull the Headset Earphones plug it automatically switches back to the Speakers, this is how I want it to work but without having to disable the HDMI in order to do it.

would anyone hazard a guess to what is going on here?.. thanks

In most cases (all that I've seen), the HDMI is inactive unless an HDMI cable is plugged into the PC.

The normal (and usual) speaker/headset mode is the speakers are muted when a headset is plugged in. Some RealTek control panel's will allow reconfiguring this so that either the speakers are muted (normal) when headset is plugged in or speakers are still active when a headset is plugged in.

If you haven't done it, install the latest AMD (ATI) drivers for the HD3450 and see if that makes any difference. Also check your RealTek HD Audio Manager (assuming you have one) to see if there are any speaker options that could affect what is happening. There are different RealTek versions, depending on the PC or motherboard vendor (in your case you should be using ASUS supplied RealTek drivers).
