How to Capture Audio from Your Speakers
Posted:

With SAM Cast, people often want to broadcast what they hear over their speakers. For example, if you have a media player that plays audio over your sound card, you might want to stream it.
To do this, the first thing you have to do is disable all Windows sounds. Any audio being played over your sound card will be broadcast, so make sure the audio being sent to the sound card is what you want to broadcast.
There are 3 possible ways of setting this up.
Method 1
Most sound devices can let you record everything that's being played over your sound card. This usually shows up as a volume control (Windows XP) or as an audio recording device (Windows Vista and Windows 7).
Make sure the appropriate input device is selected, not muted, and that the volume is loud enough. Depending on your sound device, the volume controls may be called:
-
What-u-hear
-
Wave-Mix
-
Stereo-Mix
-
Rec. Playback
Each device has its own name for this function. Some sound cards can't capture what's playing on the playback device. If that's the case for you, try one of the next 2 methods.
Method 2
You'll need a physical audio cable. Plug a regular audio jack into the output of the sound device that plays the audio, and plug the other end of the cable into the sound device's line-in. SAM Cast will capture the audio from the line-in.
Method 3
Use a program called "Virtual Audio Cables" (VAC). This creates a virtual sound device on your computer. You can play the audio into this virtual device, which will redirect the audio to a virtual sound capture device. SAM Cast will then capture the audio from this virtual sound capture device.
Visit the VAC website or go here for more information. There are also some video tutorials on using VACs.
