My Question or Issue

 Hi. I had access to an option that asked me if I use headphones or speakers. As a headphone user I changed the setting to headphones from speaker. Right after the audio quality highly decreased and I can't find the where I found this setting. I tried uninstalling and reinstalling the app, check the audio quality that was still on extreme and nothing changed. The setting was on my PC and it also changed the audio quality on my phone. Some help would be greatly appreciated, thanks.
