To make custom sounds working in Dead Before Dawn / Left 4 Dead 1, do the following:
Method 1: (for users that do not have the development console enabled ingame)
1, Make sure you have Dead Before Dawn installed (this is very important) (click the vpk if you downloaded it from any source available on this mode page and double click to install it to the correct folder.
2, Launch Left 4 Dead
3, In the options > multiplayer menu, enable the developers console
4, press the ~ key and the console will appear
4, type snd_rebuildaudiocache and wait from 10 to 30 minutes (you will see a progress bar)
5a, When the progress bar is full, open the console and type quit and relaunch the game, you are now ready to play
5b, if your game freezes press ctrl+alt+del, and bring up the task manager (bottom option of the ctrl+alt+del screen); Choose the processes tab and right-click on the left4dead process and end it.
Method 2: One-Time solution (for those who don't intend to use the console)
1: Right click left 4 dead in your steam games list and select the “properties” window
2: Choose “configure command line options
3: insert +snd_rebuildaudiocache and press enter
4, Launch Left 4 dead. You will have to wait 15-30 minutes for the progress bar to completely fill as the soundcache is being rebuilt.
5, If the progress bar is full and the game seems frozen press ctrl+alt+del, choose the task manager (bottom choise) and choose left4dead.exe from the processes tab and kill it (right click, end process)
6, your soundcache should now be built for dead before dawn.
Things to remember when playing those campaigns are:
- If you are done playing a campaign with custom sounds it is always best to quit the game and restart it if you want to play stock campaigns again (no mercy, dead air etc). Otherwise you will often not hear the SI's musical cues.
- You might hear custom music/sounds of one campaign sudenly being played in another campaign when you light zombies on fire. This is something we have absolutely no control over and is not an issue caused by our campaign but with the game's soundcache system.
- Some parts of certain soundscapes (like wind, water, elevator shafts or airpport backgrounds can be heard when you play another campaigns. We also have no control over this.
- Sometimes when you have to restart a campaign, the soundscapes stop working correctly (environment sounds like water wind etc)
I hope we made it a bit easier to play dbd as it is intended.
