I tried swapping devices when I enabled them there, and troubleshooted when the game was opened !!_weird bug_!! that happens only with this game: once I open the game setting -> "Configure my Mic" and steam voicechat option opens, and I test my mic: after testing mic (and works) if I have set on my headset both "Default device" & "Default Communication device" the volume lowers a lot and there's no way to raise it, only way is restart the PC or set "Default Communication device" on the speakers, so the headset gains volume again. Tried different combination with Default & Default Communication I enabled and disabled every single "Playback" device I tried every USB port in my computer with my headset disabled totally windows firewall, then joined the game white listed in my firewall RS2:V, then joined the game disabled totally Avast, then joined the game white listed RS2:V on my anti virus "Avast", then joined the game Restarted even my router to be sure the ports were actually applied Port Forwarded RS2:V *the following ports ->" "and these too ->" 7777 (default used by RO2), 7779 (default used by RO2), 27015 (used to contact the steam master server), 8080 (default used for the RO2 web-admin) Port Forwarded Steam the section "Steamworks P2P Networking and Steam Voice Chat" as described here Windows update are up to date (miracle that this didn't destroyed my PC beyond imagination)


every uninstall I deleted the whole RS2:V folder under "C:\Users\*User*\Documents\My Games\." Reinstalled the game 4 times, 2 times on the same SSD and 2 times on 2 different NVME

after 6 hours of cursing and swearing, I discovered this post.
