No Audio

Do your speakers come their own software?

Do this:

Check in Options > Audio that 'Audio Device' is set correctly.
May need to restart the game for it to have effect.

If persists, do what said in post #2.
(You are supposed to post here the code you receive)

 

Are you sure it's not a problem on your side? (some program conflicting etc.)
I never saw a report were audio was working intermittently. If it does not work, it would not work at all.


Do what is said in post #2, and give me a Support ID (do that after you get the problem, or we won't see anything in your logs)

 

The problem is that the game is not able to communicate with your audio drivers properly.
Users usually solve this by simply reinstalling the audio drivers, so you should try that too.

 

Some of your mods are spamming your game logs.
You should probably found and remove them.

Aside that, the game logs shows audio is working correctly.
The game is using Digital Audio (S/PDIF) (High Definition Audio Device) to output the audio.
If not correct, choose the correct device from Options > Audio.
