[2026 Updated] How to Fix PEAK Voice Chat Not Working

Part 1: What Is PEAK and Why Voice Chat Matters

PEAK is a multiplayer climbing game available on Steam. The game focuses on teamwork, balance, and timing. Players climb dangerous routes together and depend on each other for success.

Voice chat matters in PEAK for several reasons:

• Players use voice chat to guide teammates during difficult climbs
• Voice chat helps warn others before falls or mistakes
• Team members react quickly using voice instead of typing
• Proximity and team voice improve coordination during tense moments

When voice chat fails, players lose clear communication. This problem often leads to missed jumps, wrong moves, and failed climbs. Fixing voice chat restores the core multiplayer experience.

Part 2: Common Reasons PEAK Voice Chat Stops Working

Several issues can block voice chat in PEAK. Most problems come from system settings or software conflicts. Below are the most common causes.

Audio Settings Misconfiguration

PEAK may select the wrong microphone by default. Push-to-Talk may stay enabled without a key assigned. Sometimes the voice volume drops to zero without warning. These settings stop others from hearing you.

Permissions Issues

Windows privacy settings often block microphone access. Steam or PEAK may not receive permission to use your mic. When this happens, voice chat stays silent even if your mic works in other apps.

Software Conflicts

Other voice apps can interfere with PEAK. Discord, overlays, or recording software may take control of the microphone. This conflict prevents PEAK from receiving audio input.

Graphics API Mismatch

PEAK supports different graphics modes. DX11, DX12, or Vulkan may cause sync issues. Some players report voice chat bugs when team members use different APIs.

Drivers and Network Problems

Old audio drivers cause mic detection errors. Weak or unstable internet creates choppy or delayed voices. One-way audio often points to network issues.

Part 3: Step-by-Step Fixes for PEAK Voice Chat Not Working

Follow these fixes in order. Test voice chat after each step to find what solves your issue.

Fix 1: Check In-Game Audio Settings

Start with PEAK's audio settings. Many voice issues come from simple misconfigurations.

Steps to follow:

• Open PEAK and go to Settings → Audio
• Select the correct microphone from the input list
• Switch from Push-to-Talk to Voice Activation
• Increase microphone volume to a clear level
• Join a lobby and speak to check green activity bars

If you see green bars moving when you talk, PEAK receives your voice.

Fix 2: Enable Microphone Permissions in Windows

Windows privacy settings often block mic access without notice.

Steps to fix permissions:

• Open Windows Settings → Privacy & Security → Microphone
• Turn on Microphone access
• Enable Allow apps to access your microphone
• Scroll down and allow access for Steam and PEAK
• Restart your PC and launch PEAK again

This step fixes many "no sound" issues instantly.

Fix 3: Update or Reinstall Audio Drivers

Outdated drivers cause detection problems and audio bugs.

Steps to update drivers:

• Right-click Start and open Device Manager
• Expand Sound, video and game controllers
• Right-click your audio device and select Update driver
• Choose automatic search

If issues continue:

• Uninstall the audio device
• Restart your PC
• Let Windows reinstall fresh drivers

After restarting, test voice chat again.

Fix 4: Switch Graphics API in Steam

Some players report voice issues tied to graphics mode.

Steps to change API:

• Open Steam and go to your Library
• Right-click PEAK and select Properties
• Under Launch Options, enter one of the following:
• Type -dx12 for DirectX 12 or -vulkan for Vulkan.

Ask teammates to use the same API for best results. Relaunch PEAK and test voice chat.

Fix 5: Check Firewall and Antivirus Settings

Security software may block PEAK's voice connection.

Steps to allow PEAK through firewall:

• Open Windows Security → Firewall & network protection
• Click Allow an app through firewall
• Add PEAK.exe and Steam.exe
• Allow both private and public access

Restart PEAK after applying changes.

Fix 6: Reset Network Settings

Network issues often cause choppy or one-way audio.

Steps to reset network:

• Open Windows Settings → Network & Internet
• Go to Advanced network settings
• Select Network reset
• Restart your PC
• Reconnect Wi-Fi or Ethernet

Use a stable wired connection if possible for best voice quality.
