Photon V4 Server Voice Fix

Fixes voice chat on self-hosted Photon Server V4 (On-Premise) setups.

Everyone in the lobby needs this mod, otherwise players without it can't send voice.

• Works with:

  • SelfHostedPhoton
  • PhotonServerSettings

What it does

R.E.P.O's voice chat packs audio frames in a format (ByteArraySlice) that the protocol used against a V4 server can't serialize, so every frame fails with cannot serialize(): ExitGames.Client.Photon.ByteArraySlice and nobody hears anything. This mod converts the frames to plain byte arrays before they are sent and switches voice to the classic sequenced delivery modes.

Only voice frames are touched; normal game networking is left alone.

Config

BepInEx/config/com.gil.photonvoicefix.cfg

• ForceSequencedDelivery (default true): send voice as Unreliable/Reliable instead of the Unsequenced modes.
• LogVoiceStats (default true): log frames sent/received every 5 seconds while voice is active. Handy for troubleshooting; turn off for a quieter log.

Tested On

• Photon Server V4 (v4-0-29-11263)
• R.E.P.O v0.4.4.3

Important

If you are using Photon Server V5 (paid), you do not need this mod.

Changelog

2.1.1

• Rewritten for R.E.P.O v0.4.4.3 / newer Photon Voice: the old patch failed to load (EnqueueOperation no longer exists).
• Converts only voice frames (ByteArraySlice -> byte[]) instead of hooking every Photon operation.
• No longer forces Reliable/unencrypted on all game traffic or swaps PUN's serialization protocol.
• Added ForceSequencedDelivery and LogVoiceStats config options; voice stats and transmit on/off are logged for troubleshooting.

1.0.1

• Initial release.
