Update: This issue happened again after upgrading from Windows 10 to Windows 11
I decided to reformat my computer and reinstall everything. Usually when I reinstall Steam, it’s an easy process.. When I finally did open up Dota 2, the music and character talk was all static sounding. At first I thought maybe it was the sound driver or video driver. I tested this out by playing a random YouTube video and it played fine. Which makes me think this is only isolated to Dota 2. What I’ve tried:
- Reinstall sound driver. No change.
- Reinstall my video driver. No change.
What worked to my surprise was the “Verify integrity of game files” feature in steam:
Right click the Dota 2 in the library and the click properties
Click “local files” tab and then click “verify integrity of game files”
Wait until it’s done validating.
For me, after the files were done validating it says I had 198 instances of files that were invalidated. It re-downloaded those files and when I opened Dota 2 the crackling noise disappeared. Update: It looks like it no longer tells you the instances and files that are effected. The window will say validated and then it’ll redownload the effected files.
