How to use internal audio from soundcard as an audio source on Windows 7 PC

IMPORTANT NOTE: This tutorial may not work for all Windows computers depending on the operating system and what soundcard is installed. Some soundcards to not support the "Stereo Mix" functionality and therefore will not be able to be used in this manner with the Streamsie software.

Steps to set up your computer to allow Streamsie to use the stereo mix function of your soundcard.
  1. Click with your RIGHT mouse button on the speaker icon running in the task bar. 
  2. Select Recording Devices from the popup menu.
  3. On the Recording Tab, if you do not see "Stereo Mix" as one of the options, click with your RIGHT mouse button and select "Show disabled devices".
  4. If you now see "Stereo Mix" as one of the options, click with your RIGHT mouse button on Stereo Mix and select "Enable" - note, if you do not see Stereo Mix as an option, it is likely your soundcard does not support this function and cannot be used in this manner.
  5. Open the Streamsie software. You should now see "Stereo Mix" as one of the available audio sources to be selected in the audio source dropdown menu.

The Streamsie software should now record and/or stream any sound that is on your computer. Depending on your soundcard, there may be additional settings to eliminate system sounds such as dings and beeps from being included in the stereo mix. You may also be able to incorporate a microphone to include a presenter's voice in the stereo mix source, as well. If you would like to use a microphone to include a presenter's voice, as well, you will need to have a computer microphone connected to the microphone jack on your computer and follow these steps below.

Steps to incorporate a microphone into the stereo mix source.
  1. Plug in a computer microphone to the microphone jack on your computer.
  2. Follow steps 1-4 above to access the sound settings and recording tab for your soundcard.
  3. Click with your right mouse button on the microphone device in the list and select "Set as default device".
  4. Click on the microphone device in the list and then click the "Properties" button.
  5. Click on the "Listen" tab and check the box that says "Listen to the device".
  6. Note that this will mean that the sound picked up by the microphone will also come through your speakers. You may want to mute the speakers in order to not produce a feedback loop or confuse yourself.
By following these steps, you should now be able to record and/or stream both sounds coming from your computer (i.e. embedded videos or other sounds in your presentation) and your microphone input. You can then use the standard Windows mixer settings to balance out the levels between your sources.
