I want to send the audio coming from a single application like WMP or a browser to my speakers (so I can watch stuff on a secondary monitor ei. HDTV) while keeping the regular audio on the PC through headset.
Windows audio will always go to your primary sound device (I believe you can choose it in Sound Setup in the Control Panel). Some programs (eg J River Media Center) will let you choose which device they send audio to, and you can send their audio to a different device from the normal windows audio.
Is there any other software which can do this? And how about when watching video through the browser, such as with flash videos?
Also I have one sound card but a rear port which goes to the speakers and a front port which goes to the headset, don't know thought that info might be helpful.
