Capcom USA's Ray Jimenez sounds off on the Steam forums:
Hi all,
First off, I would like to apologize on behalf of Capcom and Digital Eclipse on the issues that some of you are having with Mega Man Legacy Collection. Both Capcom and Digital Eclipse have been watching the forums and are aware of the issues that are going on. We are currently collating data and in the process of coming up with fixes. The team at Digital Eclipse are extremely hard working, but they are a small indie team and it will take a while for fixes to be made and sent through QA.
So, please bear with us. I hope some of the work arounds your fellow Steam users have found can help for now, but we strive to have these fixed naturally. Please check in on this thread from time to time as I’ll use it to update you on our timeline and what fixes are going up.

The game's producer, Frank Cifaldi, adds [on Twitter]:
Hey, MMLC players: We're monitoring threads and are aware of issues. As Capcom says, fixes are coming. I can't get more specific than that.
@Omaewamo there are two separate audio issues, the crackly distortion is mostly exclusive to ps4. we suspect the popping is related too.
@Omaewamo the incorrect notes are exclusive to xbox one and pc, and we have a fix already
@Omaewamo yep, that specific issue has to do with the particular way ps4 handles audio vs. microsoft.
