Depend your net bandwidht, can you use
sv_maxrate 50000
sv_minrate 30000
You could try old audio codec, disabling this
Code:
"sv_use_steam_voice" = "1"
replicated
- Enable/disable using Steam Voice instead of the old voice codec (if enabled, voice_inputfromfile will no longer function).
If not help... change to
vaudio_miles (very shitty voice, like Microsoft Sam, you not like it)
Code:
"sv_voicecodec" = "vaudio_speex"
- Specifies which voice codec DLL to use in a game. Set to the name of the DLL without the extension.
