Hi Wilson,
Welcome to Microsoft Community.
I'm Hahn and I'm here to help you with your concern.
It sounds like you're experiencing a few different issues with your HyperX Quadcast microphone. Let's go through each issue one by one and see if we can find a solution:
You can't hear your own voice while speaking to the mic:
This is a common issue with microphones that don't have built-in monitoring, which allows you to hear your own voice in real-time. The HyperX Quadcast doesn't have a built-in monitoring feature, so you'll need to use headphones or speakers to hear your voice while recording or streaming. If you don't want to use headphones, you can try using speakers instead.
You can hear your own voice through the headphones connected to the microphone:
This is likely due to a setting in your computer's sound mixer. When you connect your headphones to the microphone, the sound is being routed through the microphone and back into your headphones, creating a feedback loop. To fix this, you'll need to adjust the settings in your computer's sound mixer to prevent the microphone from playing back through your headphones.
Here are the steps to adjust the sound mixer settings:
Right-click on the speaker icon in the system tray and select "Open Sound settings".
Scroll down to the "More Sound Settings" section and go to the "Sound Control Panel".
Select the "Recording" tab.
Right-click on your HyperX Quadcast microphone and select "Properties".
Click on the "Listen" tab.
Uncheck the box that says "Listen to this device".
Click "Apply" and then "OK".
Make sure your mic is enabled and set as the default device in your device’s settings. You can do this by going to Control Panel > Hardware and Sound > Sound > Recording tab. Right-click on the HyperX Quadcast mic and select Enable and Set as Default Device. Then click on Properties and go to the Levels tab. Drag the volume slider to 100 and click OK.
Make sure your mic is selected in Zoom. During a meeting, click on the up arrow next to the Microphone icon and choose HyperX Quadcast from the list. You can also test your mic by clicking on Test Speaker & Microphone.
Make sure you have allowed access to your microphone in Zoom and other apps that might use it. You can check this by going to your device’s app settings and ensuring Zoom has permission to access your microphone.
Make sure you are not muted in Zoom or in other programs that might interfere with your audio. You can unmute yourself by clicking on the Microphone icon in Zoom or by pressing Alt+A on your keyboard.
You see a pop-up saying "no jack information":
This could be a driver issue. Try downloading and installing the latest drivers for your microphone from the HyperX website.
If you're still having issues after trying these solutions, you may want to contact HyperX customer support for further assistance.
If there is anything not clear, please do not hesitate to let me know.
Your Sincerely
