+# CS2 Fix Demo Voice Chat
+
+Counter-Strike 2's SourceTV currently does not record player's voice chat by default unless the server has `sv_alltalk 1` enabled. This plugin modifies the SourceTV's voice flags to hear the voices of all players.
+
+This should work with any gamemode/config as the player's voice flags are not changed.
+
+## Requirements
+- Metamod
+- CounterStrikeSharp (>v143)
+
+## Installation
+- Download the [latest release](https://github.com/b0ink/CS2-FixDemoVoiceChat/releases)
+- Upload the contents of the `/Release` folder into `game/csgo/addons/counterstrikesharp/plugins/FixDemoVoiceChat/`
+- The SourceTV's voice flag fix will be applied on each round start
+
+# Demo Playback
+To hear all player's voice chat, use the following commands in your console **before** loading up the demo:
+```
+tv_listen_voice_indices -1
+tv_listen_voice_indices_h -1
+
+playdemo yourdemo.dem
+```
+Per [u/roge-s's comment on reddit](https://www.reddit.com/r/GlobalOffensive/comments/17i3zuc/comment/k6s7fjz), these convars can be used to select specific players to hear in demos:
+```
+tv_listen_voice_indices 0: Bitfield of playerslots to listen to voice messages from when connected to SourceTV, default is none
+tv_listen_voice_indices_h 0: High 32 bits of bitfield of playerslots to listen to voice messages from when connected to SourceTV, default is none
+```
+> These are both client-side convars, so I don't think they will affect the demo recording. You might be able to use them client-side during demo playback, but I'm not sure. That being said, I would expect them to work for live CSTV spectators (just remember that they need to be set on each of the spectators' game clients).
+Going by the descriptions of these convars, you need to enable each bit for the corresponding player slots you want to be able to hear. `tv_listen_voice_indices` would be used to configure player slots 0-31, and `tv_listen_voice_indices_h` for player slots 32-63.
+
+> The confusing part about this is that the CS2 console seems to be treating these variables as signed 32-bit integers. That makes setting up these convars a bit annoying since you need to deal with the two's complement encoding that signed int32's use on x86 platforms.
+With this all in mind, I would expect that by setting both of these convars to the decimal value of -1, you should be able to hear everyone.
+
+> If you want to selectively hear players, you can use a 32-bit two's complement integer calculator such as this one: https://www.binaryconvert.com/convert_signed_int.html?hexadecimal=0
+> For this calculator in particular, just enable squares at the bottom corresponding to the player slots you want to hear, then click to "convert to decimal", and then u
