[OBS] No game sound! Change desktop audio settings and it will come on!

When you have connected the capture board to the game console and monitor, and are about to transfer the game screen using OBS, you may run into a problem where you cannot hear the game sound.
The answer is to change the “Audio Output Mode” to “Desktop Audio (WaveOut)”.
Let’s take a look at the specifics.

Change the audio output mode to Desktop Audio (WaveOut)

We will configure the settings to output game sounds from the computer.

From within [Source], click the gear icon of the game console from which you want to output sound (in the case of the photo, the “Switch” is connected) to open the properties window of the video capture device.

Scroll down to [Audio Output Mode] and change it to [Desktop Audio Output (WaveOut)] since [Capture Audio Only] is selected as the default setting.
Now you are ready to output game sounds from your computer.

Change the input destination of the game sound to the capture board.

Change the settings so that the output destination for the sound from the game console is the capture board.

After changing the audio output mode to [Desktop Audio Output (WaveOut)], check the [Use custom audio device] checkbox.
After checking the box, the item 【Voice Device】 will appear.
The default setting for the audio device may be [Microphone Device], but change this to the capture board connected to the game console (in the case of the photo, [Digital Audio Interface [MiraBox Video Capture]]).

Did the game sound come out of your computer?

If you set the audio output mode and audio device as above, you can get the game sound from the speakers of your computer, and if you plug in earphones, you can also hear the game sound through the earphones.

Steps to take if you get game sound from your computer but it causes feedback

I know I should have said this before, but if you follow the above steps to make game sounds from your computer, you will surely get feedback (the sound gets louder and louder).
The correct procedure to avoid feedback is as follows
Check [Use custom audio device].
Select a capture board from [Audio Device].
Change [Audio Output Mode] to [Desktop Audio Output (Waveout)].
Leave the audio output mode at the default setting of [Capture Audio Drink], change the audio device, and finally change it to [Desktop Audio Output (WaveOut)] to avoid feedback.

Now that the settings are complete, let’s take a look at the [Mixer] in the main OBS window.
The level meter for [Desktop Audio], which was not swinging earlier, now moves in conjunction with the game sound.

How to adjust the volume of the game coming out of the computer using the volume slider of the desktop audio

If you can adjust the volume of the game sound coming out of your computer speakers by moving the volume slider of the desktop audio, it would be easier to do something.
You cannot adjust the volume of the game sound with the slider without making various settings.
You can also learn how to adjust the volume coming out of your PC with the OBS volume slider, if you are interested.

Why I can’t hear the game sound even though the microphone volume meter is working?

The reason why you can’t hear the sound of the game no matter how much you turn up the volume, even though the level meter on the [microphone] is moving, is because the microphone is just picking up the ambient sound (life sound).
This is because the microphone is only picking up the ambient sound, not the game sound.

Microphones are picking up environmental sounds and the levels are swinging

Let’s find out which microphones are picking up what sounds.

I clicked on the gear icon in the bottom right corner of [Microphone] and opened the properties, and found that the device was set to
The device was set to [Default].

Let’s find out what the default microphone device is.
Go to [Start] -> [Control Panel] -> [Sound] -> [Recording] tab, and you will find several types of microphone devices.

The second [High Definition Audio device] from the top is the default microphone device.
The reason why the microphone meter was moving was because the computer’s built-in microphone was set as the default microphone, and that built-in microphone was picking up ambient sound.
Examples of ambient sounds
My voice
The sound of the TV in the living room
Environmental sounds such as typing on the keyboard
