Prepare Your Hardware and PC Settings
Before switching Astro a40 to PC mode, gather all components and update drivers to avoid audio drops or voice chat issues.
Check your cables and dongle
The A40 bundle includes a 3.5 mm dongle and a USB-A to micro USB cable. Confirm both are present and not damaged, as they carry audio and microphone signals to your PC.
Install realtek and audio drivers
Head to Device Manager on Windows, update audio drivers, and install any Astro software if available. Up-to-date drivers reduce latency and prevent the headset from being recognized as a generic device.
Switch Astro A40 to PC Mode Physically
Changing the headset to PC mode is mostly about how you connect the cables rather than changing headset hardware.
Turn off the headset and detach from console
Power down the A40 and unplug the controller adapter from your PlayStation or other console. This prevents audio conflicts while you reroute the connection.
Plug the 3.5 mm dongle into your PC
Insert the dongle into the headphone jack on your PC. The dongle converts the proprietary connector to standard 3.5 mm, enabling line-level audio output and microphone input.
Connect the Headset and Verify the Route
Once the dongle is seated, connect the A40 to it using the 3.5 mm cable built into the headset boom.
Use the USB cable for power and detection
Plug the USB-A end into your PC so the headset can draw power and be fully recognized. Many users skip this, which can leave the microphone unstable on some systems.
Confirm audio output and microphone devices
Open Sound Settings on your PC and set the Astro A40 as both the default playback and recording device. Test with a voice recorder or in-game chat to ensure clarity and low noise.
Configure Audio Software and Game Settings
After the basic connection, fine-tuning software and game settings helps you get clean audio and stable voice chat.
Set game audio to PC speakers only
In your game sound menu, route in-game audio to your PC speakers or headphones separately if needed. This keeps game sounds clear while the A40 handles voice chat and main output.
Adjust voice chat and microphone levels
Open Discord or TeamSpeak and set the Astro A40 as the input device. Use the in-app level meter to avoid distortion and keep your voice clear to teammates.

FAQ
Reader questions
Why does my microphone not work after switching to PC mode?
Check that the USB cable is connected so the headset is fully recognized, and confirm in Sound Settings that the A40 microphone is set as the default device.
Can I switch back to console mode without turning the headset off?
Yes, you can unplug the dongle and reconnect the controller adapter, but powering off the headset first prevents audio glitches and keeps both devices synced.
Will using the 3.5 mm dongle add noticeable latency?
No, the dongle is a simple analog adapter with minimal impact on latency. Any delay usually comes from software settings or wireless transmission, not the cable connection.
Do I need special drivers if I only use the headset for listening to music on PC?
Basic audio works without extra drivers, but installing the latest audio and realtek drivers ensures microphone support, better sound quality, and stable performance in games and chat apps.
