Every time I listen to music on my PS4 the songs start off at a normal volume and sounds fine. However as soon as the song increases in volume the output volume drops noticeably and then rises again when the song quiets down. I've been looking for a solution and have found that on pretty much every device except the PS4 there is a sound equalizer that can be adjusted to correct this. If an in app equalizer could be added that would be a huge help. Thank you.
