Halo The Master Chief Collection Audio Issues
It depends on what you're listening with, but it seems that Halo: The Master Chief Collection has some audio quality issues if you're playing the game on any sort of higher end headset or home theater system. Even ignoring YouTube compression, the audio does some somewhat muffled and lower quality that it should be. Apparently it's not that bad if you've got some mediocre sound gear.
Granted the first game in Halo: The Master Chief Collection is Halo Reach, which came out in 2010. These sorts of things are somewhat expected, though they could have been improved.
I'm also having issued with stuttering audio when playing coop.
The audio mixing doesn't seem very good either. Some parts of the game that should seem loud are quiet, and are drowned out by things that shouldn't be as loud.
Halo Reach is a great game which brings back a lot of memories. Outside of the audio issues I've been really enjoying it. Hopefully we can see these things fixed later.
FYMRefunding on Steam till it's fixed. This is unplayable levels of bad. This video doesn't really do it justice honestly, it sounds even worse while playing.
