Quoted from viper001:For over a year (before the games started being produced) we heard endless assurances and reviews of this new platform that the sound was going to be "better" than the original, primitive DCS compressed games. Most of these reviews came from folks that had never seen/heard/played one in person as they were just parroting what the salesmen was telling them.
My advice, if the sound is not "better" as was advertised you should not be spending money fixing it, you should be putting in tickets to see what the MFG will do to fix it. For one thing such changes could be voiding your warranty if you do. Your baseline is the original game, for the most part that platform did not crackle, and the voice call outs could be heard just fine even on the stock speakers. IMHO.
Now having my MMr for about a month, I can weigh in on this with a more detailed review of the sound.
-Voices are crystal clear - better than WPC'95.
-Music is accurate but lacks "oomph" - however, the original might have been like this - I'm just used to games with upgrades speakers and external subs. Once I hooked up my MMr to an external sub, it had "oomph" like my other games.
-Game power up "bong" sound sounds like shit compared to a real B/W. Dunno why...but when I first heard this distorted sound, I thought maybe the speakers were busted and that's why my sound lacked "oomph". I think they've just got the volume for that sound set wrong or it's an emulated sound effect or something. Oh well...doesn't affect the in-game sound.
-The voice levels of the castle bosses are a bit low. They're there and clear, but often get drowned out by music and sound FX. Princesses & trolls are loud and at a good level. My guess is that this has something to do with using the uncompressed original sound files - maybe the compressed ones had their levels adjusted in software or something.
Sounds like PPS/CGC are on the case, and some (if not all) of these issues should be addressed in a software update.
