Audio output no longer changes automatically, why?

hi guys I am using windows 7 64bit. The problem I got is when I used to connect my TV via hdmi or my gaming headset via usb my laptop would automatically switch the audio output to that device. Now it no longer does this for some unknown reason. Every time I connect a device I need to go into the playback device settings and disable the device I am using in order for the device I just connected to work. Why is it now doing this as it is very annoying???

thanks.

 

I had a similar issue with an ATI card via HDMI, I had to do a repair on my ATI driver (part of it is HDMI audio). I am not sure if NVidia works the same way though.

 

why would I have the same problem with the headset through usb and how did you fix the problem?

 

Which laptop is this on? You never told us which one it was??

 

Thought as it is an os issue it didn't matter but I have an msi gt70.

 

Are you running any software such as creative/realtek and if so have you tried reinstalling it?

 

I've used this little app for years. Works great for quick switching audio outputs: http://blog.contriving.net/2009/05/...-between-headphones-and-speakers-soundswitch/

 

I use realtek for the soundcard and creative for Headset. I havnt tried reinstalling them. I'll give it a shot.

 

Ok I reinstalled the drivers and software and it seems to of worked. Thanks!
