Room code and browser

Fix the session before the fun disappears
Start with quick checks, change one thing at a time, and stop when the failed layer is isolated.
No audio or delayed voice
Voice chat not working
Confirm the input path from operating system permission through Steam voice settings and the game.
Open voice checklistUse the five-minute baseline first
- Have all three players fully exit the game.
- Let Steam finish any pending update, then restart Steam.
- Confirm that every player launches the same current build.
- Create a fresh room and test both room code and global lobby browser.
- If one player still fails, test that player on a different network.
Keep the test clean: Do not change firewall, VPN, input device, and host at the same time. One change should answer one question.
