I don't know if this is already sorted out on the main build. The game had many flaws, but what unsettled the most was the audio. I'm not even a guy who understands anything about audio design or sound in general. I just thought it felt wrong several times when I was playing. I don't mean to bash, just provide my honest feedback. Here some points I had experienced.
Music didn't play at times, leaving an awkward silence.
Other times, the music playing didn't match what was happening on screen. Specially in Fort Tarsis.
Picking up a codex sounds like throwing a hard cover book on the wall.
Audio in the menus felt off and contributed to make the UI feel unresponsive. The volume of beeps and boops didn't always match the action, if you can tell what I mean.
I once got a bug where the game went completely silent and I had to restart. Never seen a bug like this in 20+ of gaming.
Interceptor melee sometimes go total quiet. You're shredding something to pieces and you don't hear the satisfaction sounds.
The worst is the reward screen post mission. When you see those numbers XP going up, medals earned etc. And you don't listen to anything which is happening.
TL;DR: the game sounds bad even for a guy who doesn't usually pay attention to this. Sorry por poor english.
We are aware of all of these issues and have made a lot of progress over the past couple months. The release build should address most of this feedback - but we will continue to improve over the course of live service, so keep telling us what you think!
A lot of us have been around since mass effect 1, so understand that we take a great audio experience seriously, and are committed to delivering one for you :)
