WIN7 dual sound card switching instance

If more than one screen, a game to see a movie, and then the game sounds and movies separate output, you can use a dual sound card to complete this function. The general motherboard will bring a onboard sound card, and then you can add a PCI or USB independent sound card, of course, you can use Bluetooth audio rendering as a second sound card. Here with a Bluetooth headset when the second audio output, speakers play games and other computer sound, Bluetooth headset play movie sound.

If it is Bluetooth audio rendering when the sound card, first link Bluetooth headset (or speaker), the system will automatically download the corresponding Bluetooth audio rendering driver, the device can see the corresponding Bluetooth driver

Turn on the Volume control option, and "Bluetooth audio renderer" appears in the sound device, with the Bluetooth program and speakers hooked up

You can set the default playback device on the Sound Settings page. If you just link the Bluetooth headset, Bluetooth will become the default device, so the Bluetooth headset link on the rear speakers will not sound and automatically go to the Bluetooth headset. Here we can set the default device as the speaker. All the voices will come back to the speaker.

Then, we open the video playback software, here must be selected to set up audio output of the broadcast software, many of the current mainstream of the Fool-like software (such as Storm Audio, QQ music, etc.) is unable to set the audio output device. Video personal likes to use KMPlayer, audio with foobar2000.

Take KMPlayer as an example (others can set audio output similar), open the player, and right-click the audio-> Audio renderer-> bluetooth audio renderer.

When set, the KMPlayer player's voice is output to the Bluetooth headset. And the computer game, music and other sounds are left on the speakers. This is not very fun oh ...
