Question Audio volume sometimes muffled/low? (Video Included)

I have an audio source that plays 2D sounds, as these are the sounds that can be heard regardless of where the player is, one such sound is the "Jump" sound effect. Sometimes when the player jumps though the sound seems to play at a lower, or muffled volume.

My sounds are being played like this

Code (CSharp):

1.                
2. aS.PlayOneShot(audioClips[i], PlayerPrefs.GetFloat("SFX") * PlayerPrefs.GetFloat("Master"));
3.  

During testing "SFX" and "Master" are both set to 1 and I've confirmed this with a log.


Video starts with me using a shortcut to activate the sound, then ends with me actually jumping to play the sounds.

 

me too,sometime when overrall sound is too loud the volume will reduce i dont know why. help please
