Audio help for computer and TV settings

[JDOD240]

Im not a tech geek so i'll try to make this make as much sense as i can.

I have my TV hooked up to my computer using HDMI. The audio and video plays just fine.

My question is. I have a PC monitor i use for my computer. I also have my TV hooked up to my PC through HDMI. How do i get audio to play through my external speakers that are hooked up to my PC. while having the audio playing on my TV.

Heres the tricky part. I use my TV so my son can watch movies and cartoons i have on my computer also from netflix. So i was wondering if there was a way to get audio from my external speakers. Audio thats not coming from whatever hes watching. So like he could be watching a cartoon and i could be playing a online game and the only audio coming from my external speakers that are hooked up to my PC is from the video game. while he can hear his shows from the tv speakers.

My audio options in the Volume mixer are 47LD500-C (NVIDIA High Definition Audio) and option is Speakers (VIA High Definition Audio) also im runing Windows 7 OS

Hope that made enough sense

Windows built in volume mixer wont have the option but your audio chips specific control panel might have a setting to use both.

Otherwise you would need to find an hdmi adapter that will extract the audio and convert it to analog but still allow the digital audio stream to go to the HT system

You could try this program:

It's not clear in the description what a "device" is but the trial is free. There should be way to do this under windows but they have never realized that it would be useful.
If you can find a video board with 2 HDMI outputs the drivers for that might support separate audio streams for each.
