PEAK: Fixing Voice Chat Audio Problems

In-game voice chat issues in PEAK are frustrating but often solvable. Many players report seeing mic activity in mirrors without audio transmission, even with correct settings. Below are troubleshooting steps to restore communication.

Essential Checks First

Confirm voice chat is activated within PEAK’s options
Verify microphone/headset selections in both game and system audio settings
Restart PEAK after adjusting any microphone configurations
Validate game files via Steam to eliminate corruption issues

Graphics API Synchronization

Ensure all party members use the same graphics backend (Vulkan or DirectX12). Change this via launch options and coordinate with teammates for consistency.

High-End Microphone Fix

Premium USB mics (e.g., Focusrite Scarlett) might only function when connected to the leftmost USB port. This simple hardware adjustment has resolved issues for many users.

Eliminate Audio Software Conflicts

Virtual audio tools like Voicemod or VoiceMeeter often interfere. Temporarily disable or uninstall these programs before launching PEAK.

Domain Whitelisting (For Network Experts)

If using DNS blockers, ensure ns.photonengine.io isn’t blocked. Test accessibility by entering the address in a browser – “HTTP not supported” confirms proper access. Unblock if necessary and restart the game.

Unconventional Solutions

Start a muted Discord call before launching PEAK – some report this triggers proper mic functionality
Switch Windows output devices, start the game, then revert the setting

System-Level Adjustments

Update Windows OS, then run PEAK as administrator. Confirm security software isn’t blocking game permissions.

PEAK’s voice system shows peculiar sensitivities. The graphics API mismatch and microphone port issues are prime culprits. If standard fixes fail, some players report spontaneous resolution after daily server resets or software updates.
