18991899

刚下来GBT的2026整合版本，自己升级到2031，进服大概玩十来分钟就说，服务器连接丢失
网络一直都在50Ping左右，看了看控制台有这段东西，应该是音频方面的问题，但具体是什么要怎么解决，斑竹教教我啊

S_StartSound: Failed to load sound 'playersurvivorvoicemechanicgrabbedbysmoker01a.wav', file probably missing from disk/repository

Server connection timed out.
SoundEmitter:  removing map sound overrides [2 to remove, 0 to restore]
