Win7 dual sound card switching example tutorial

If you have multiple screens, one to watch a movie, and then separate the game sound from the movie, you can do this with a dual sound card. The average motherboard will have an onboard sound card, and then you can add a PCI or USB independent sound card, of course, you can also use Bluetooth audio rendering as the second sound card. Here use a Bluetooth headset as the second audio output, the speaker plays the game and other computer sounds, and the Bluetooth headset plays the movie sound.

If it is a Bluetooth audio rendering sound card, first link the Bluetooth headset (or speaker), the system will automatically download the corresponding Bluetooth audio rendering driver, at this time you can see the corresponding Bluetooth driver in the device

open the volume control options, sound equipment will also appear in & ldquo; Bluetooth audio rendering program & rdquo ;, Bluetooth VGH program and speakers

in the settings page you can set the default sound The device being played. If you just link the Bluetooth headset, Bluetooth will become the default device, so the Bluetooth headset will automatically go to the Bluetooth headset without a sound on the back speaker. Here we can set the default device to the speaker. All the sounds will return to the speakers.

Then, we open the video playback software, there must be able to choose some set audio output broadcast-party software, many of the current mainstream fool software (such as STORM, QQ music, etc.) are not set audio Output device. Video people like to use KMplayer, audio with foobar2000.

Take KMPlayer as an example (others can set the audio output similarly), open the player, right click and select Audio -> Audio Renderer -> Bluetooth Audio Renderer.

After setting, KMPlayer player's sound is output to the Bluetooth headphones. The sounds of games, music, etc. on the computer are left on the speakers. Is this very fun? . .
