Fix: Kast Audio not Working

Audio in Kast may not work due to the wrong configurations of input/output devices. Moreover, a disabled stereo mix setting may also cause the issue. The affected user encounters the issue when he tries to stream/watch movies through Kast but no audio is broadcasted. For some users, the issue started after 3 to 4 minutes of starting the stream.

Before moving on with the solutions, check if your OS (Windows, Mac, etc.) and system drivers are up-to-date. Moreover, make sure the person watching the Kast stream has moderator rights. Manually mute/unmute your mic to clear out any temporary glitch. For elucidation, we will guide you for the solutions for a Windows PC.

Solution 1: Enable the Stereo Mix in the Sound Settings of Your System

Stereo Mix feature lets a user record the output stream of his computer (like speaker outputs, live, streaming audios, system sounds, etc). Kast Audio might fail to work if the Stereo Mix in the sound settings of your system is disabled. This conflicts with the operation of Kast. In this scenario, enabling the Stereo Mix may solve the problem.

1. Exit Kast and make sure no Kast-related process is running in the Task Manager of your system.
2. Now right-click on the speaker icon (on the system’s tray) and then click on Open Sound Settings.

   

3. Then, under the Master Volume section, click on Manage Sound Devices.

   

4. Now, expand the option of Stereo Mix (in the Disabled section) and then click on the Enable button.

   

5. Now, launch Kast and navigate to its Audio settings.
6. Then check if the Stereo Mix option is available there, then enable the said option and check if Kast is clear of the error.

   

7. If not, then check if there is another device disabled in the Disabled section (at step 4), if so, then enable that device.
8. Now change the Kast’s audio settings to that device and check if Kast is working fine.

Solution 2: Change the Input Device of Kast to Computer Audio

You may encounter the error at hand if the input audio of Kast is different than the computer audio. In this case, setting the input audio as the computer’s audio may solve the problem.

1. Launch Kast and navigate to its Audio Settings.
2. Now open the drop-down box of Input and then select Computer’s Audio.
3. Then change the Voice Mode to Open Microphone.

   

4. Now relaunch Kast and check if the audio issue is resolved.
5. If the Computer Audio option is not available at step 2, then try to plug in a headphone/aux cable (not a USB connection) and then check if the said option is available. If so, then repeat steps 1 to 4 and check if the issue is resolved.
6. If not, then Launch Kast and navigate to its Audio Settings.
7. Now, select the Default Device for both input and output devices.

   

8. Then relaunch Kast after saving the changes and check if it is operating fine.
9. If not, then switch the Input in the Audio Settings of Kast to Computer Audio (steps 1 to 4) and check if the issue is resolved.

Solution 3: Change Output Device to Speakers/Headphones

You may encounter the audio issue if the output device of your system is set to Speakers (not Speakers/Headphones). In this context, setting the output device of your system to Speakers/Headphones may solve the problem.

1. Exit Kast and make sure no Kast-related process is running in the Task Manager of your system.
2. Now right-click on the Speaker icon (on the system’s tray) and then select Open Sound Settings.
3. Then expand the dropdown option of Output (usually, the first option) and select Speakers/Headphones.

   

4. Now check if the Kast audio issue is resolved.
5. If not, try to change the output device to your monitor speakers and check if the issue is resolved.

Solution 4: Use a Virtual Audio Device

If nothing has worked for you, then you may have to use a virtual audio device like VB cable/Blackhole/Soundflower (2 ch) to overcome the problem.

1. Download and install the VB cable driver.

   

2. Now restart your system and upon restart, right-click on the speaker icon in the system tray.
3. Now, click on Open Sound Settings.
4. Then make sure that output and input devices are set to Cable in or Cable out.

   

5. Now, launch Kast and navigate to its Audio Settings.
6. Now make sure that input/output devices match the VB Cable setup.
7. Then relaunch Kast and hopefully, the audio issue is resolved.
