Citra causing background sounds to scratch

Issue :

Starting Citra up causing any sounds in game and in the background (e.g videos, music) to scratch, Citra cause these sounds to scratch similar to the speed of dripping tap. These scratchy noises would start to appear if there are any sounds in the background, in game or even when there are no game being play on Citra. Previously restarting pc would solve the issue but now restarting does not work.

Diagnostic Log

In order for us to provide better support, we need to see the log generated by citra. This guide will walk you through how you can obtain the log file: How to Upload the Log File

The log file mentions you’re using a headset connected via USB. Which makes me think that you’re perhaps using a headset with some sort of virtual surround sound. If that is the case, try disabling that in your headset’s audio app and see if that affects the audio problem at all. We had a case a long while ago where that was the problem.

If that isn’t relevant try switching Citra’s audio output engine to sdl2 in Citra’s audio settings.

I tried switching to sdl2 first and it didn’t work, there’s no option to turn off virtual surround sound in the app so i closed the app and the effect of the equalizer are still on so that didn’t solve it either. My audio jacks on the motherboard is not working so i had to use USB soundcard, i guess i will have to accept the scratching sound for better sound quality.

Right click on your volume icon on your task bar. There should be a “Spatial audio” option there if your headset supports it. If it does, make sure that’s turned off. Other than that, please upload a new log file using the steps below:

  1. Open Citra, then go to File>Open Citra Folder (Citra>Open Citra Folder if on MacOS) and open up the log folder. Now keep that open in the background.
  2. Launch your game and encounter the problem; crash/slowdown/glitch and close Citra if it doesn’t do so by itself. Do not restart Citra as that will wipe the log of important information!
  3. Now upload the log file in this chat.

There might be some other information that the log file can tell us.

I turned off Spatial Audio since my head set does support it, still the same but i did follow the instruction and here’s the log that was generated:

Here’s some issues I found with your log that might help.

  • Please enable the Vsync option if you are experiencing screen tearing.
  • You have mods installed. This might cause weird behaviour or crashes. Please disable them and retest if your game is experiencing bugs or crashes.

Please try out a portable Citra build to rule out any issues with your current Citra installation or appdata:

Go to Download Citra - Citra and select Manual download. Then under Nightly Build, click on your operating system’s icon to the right of the latest build available to download the build.
Extract it (.7z can be extracted using Winrar or 7zip) and put it where ever you wish. Inside the extracted mingw folder, create a folder called user. This Citra should now store all of its config, save files and such inside of this user folder.
Check to make sure that this user folder is in the same folder that contains citra-qt(.exe)
Now run the citra-qt executable found inside of the mingw folder and run your game.

See if this makes any difference for your sound problem.

I tried the portable build of Citra Nightly and created the user folder according to the instructions, the sound problem is still there in the portable build. But i already got used to the scratching sounds after using Citra for days now so i think i can bear it, thanks for trying to help.

Sorry we couldn’t work out why this is happening. If you happen to find out in the future, I’d like it if you’d let us know.
