The notebook 💻 has its own speaker, and I have a Bluetooth speaker 🔊, together it is 2.1 channel. So how to make them work at the same time?

Let me talk about the result first: Bluetooth playback devices will have delays, so the multi-channel of this method group is only suitable for wired speakers. Of course, if you want better playback effects, you should buy the whole set directly. multi-channel playback device.

My equipment environment is a laptop and a monitor that supports hdmi audio output. The audio can be connected to speakers or headphones through the monitor. Theoretically, any win10 system with dual playback devices can achieve the effect of simultaneous output of dual devices through this method.

# Implementation process

1. Right-click the sound icon 🔊 in the taskbar, the following interface will appear and then click the sound option:

2. On the sound setting page, select the {% label success@recording%} tab, and you will find a device called {% label success@stereo mixing%} . {% label default@ (if it does not appear, right click on the disabled device) %}

3. Select the {% label success@listen%} tab in the stereo mix, check {% label danger@listen to this device%} by default The playback device is just fine.

4.Finally, click the sound icon on the taskbar in the lower right corner🔊 and select the device you just set as the default device:

In this way, when playing audio, the device’s own playback device and the playback device you set up later will be used at the same time. There are only two playback devices at most. I tried three different playback devices, but only two have sound.
