No Audio In-Game (SOLVED)

[HungryArtBean]

I have had this issue since the beginning of the year and literally nothing has helped, not even the update.

I have 0 audio in-game but there is audio in the start up cut scenes, like the valve logo and the cut scene of the second cast. Once I enter the main menu however, there isn't even audio when switching game options, like solo survival or vs. Being in the game doesn't do anything either as there are no sound cues for specials or zombies. No gun shots or survivor dialogue. Just silence, which makes the game very difficult to play since captions don't help all that much when playing.


Everything I have tried up to this point,
1. I have already tried the Verify Integrity Game Files, it did not work.
2. I have already tried ;snd_rebuildaudiocache ;snd_updateaudiocache ;exit, it did not work.
3. I have check my sound mixer and made sure the game is at 100 and not muted.
4. I have updated my audio drivers so there is not an issue there.
5. I have uninstalled and reinstalled the game several times and nothing worked.
6. I even installed Razer software (Which I don't think I needed to begin with) and there was no change. I only installed it because a friend recommended it could be a solution.
7. Steam support did ♥♥♥♥♥♥♥♥♥. I sent 3 reports to them and they all sent me a response an hour later telling me there are too many files to check and to check their faq for general audio errors. I have given up trying to get them to help me since they all sent the same exact ♥♥♥♥♥♥♥ message with different names at the bottom, so I just assume no one actually helps with out-of-date games and just uses bots to send responses.


I have tried absolutely everything and nothing works. This is the only game I am having issues with. Steam games that have no issues for me are Gmod, TF2, Elsword, VRChat, Among Us, and Left 4 Dead 1. Non-steam games are fine as well like Minecraft, Runescape, Sims, and Roblox. Even things like youtube or clip studio paint work just ♥♥♥♥♥♥♥ fine.

I have reached out to everyone and no-one has any idea what is wrong with the game. At this point, if no one else has any idea, I will just wait till I have enough to buy a new computer and play L4D2 again since this is one of my favorite games to play. But I really want to get this error fixed if possible


(EDIT)
FOR SOME ♥♥♥♥♥♥♥ REASON,, The audio output was switched to conexant instead of default. That was it. That was the whole problem. I have 0 idea on how it switched since I do not mess with audio unless I need to, but that was the whole error.
I had help from someone who agreed this was a ♥♥♥♥♥ and a half to fix, but I no longer have any trouble with this.
Anyone who also has this issue or ever had this issue, just double check your l4d2 audio. It's such a stupid reason to glitch out but it'll ♥♥♥♥♥♥♥ happen.

Do you have anything else in your launch options? Some time ago I put in a command from a guide which was related to the game's RAM usage, and it caused the sound to disappear completely after a few seconds in the main menu. Removing the command fixed the issue.

If this doesn't help, then sorry. I don't know a lot about the Source engine and it's spaghetti.

Quick edit: it was either the "-USEALLAVAILABLECORES" command or the "-heapsize (number)" command. I don't remember which one caused the issue.

I don't have any commands set for launch, but maybe that code will fix it instead? Would you mind telling me the code?

I edited my original post to include them. I found them in this guide originally.

I've installed addons, but I've uninstalled them and reinstalled the game and tried to see if that was the issue and it wasn't. Sound fix addons didnt help either.

Hi mate,

Can you confirm that your "Headphones/Speakers" are the only active device in the Playback tab of your Windows sound control panel? Go to Control panel ----> Hardware and sound ---- > Sound and make sure there are no other devices enabled except your active audio device.

If you can't find anything suspicious in the Playback tab, it could be a third party software interfering with the audio of the game, go to your Task manager, click on Startup and disable any suspected program or all of them for testing, then reboot your computer and check if you have sound in game or not.

Hi again mate, a few days ago a user reported a problem about no sound only in Left 4 Dead 2 similar to yours and it turned out he had to uninstall a third party program called Ear Trumpet, as only disabling it still caused the same issue.

If you have any third party software that could alter sound control I would recommend to uninstall and check again, as you've made sure the game files are correct and tried all possible solutions, if you need help I've added you to the friends list and we can sort this out.

EDIT 29th October :-

Added OP to friends list, problem was fixed by changing the audio output of Left 4 Dead 2 in Windows Sound ---> "App volume and device preference", as it was set to a different option other than "Default", setting it back to default allowed sound in-game to work.
