Sound is very muffled and quiet

I tried all the sound settings but nothing has a very big impact. Explosions and everything lack any sort of bass. Anyone have the same issue or a fix?

I had to have a long play with the settings to get something remotely decent.

Best I could get was to set it to "Speakers" (despite using headphones) and the other option above it (can't remember what it is called) to "Surround" rather than the "Auto" option it defaults to. Still not great but it was definitely an improvement.

I remember the BF5 beta sounding flat and boring as well. At the time, I said to a friend that it somehow sounds like nothing is happening, even in a highly contested area. It improved a LOT on release though so hopefully that's the case this time as well.
