The game goes completely mute every time I fast travel or travel via the war table forcing me to have to close the game down and start it up again a couple of times before I get audio back.
A bug, certainly, but not unplayable.
Audio during cut-scenes are completely messed up making it sound as if the characters are possessed or speaking backwards.
Again, not unplayable.
My saves keep getting corrupted for some weird reason wich means I simply can't load them, making it more or less impossible to make any real progress in the game. If the game does load it often freezes right after having loaded, or my character seems to be stuck in one spot unable to move.
This actually is an issue warranting the term 'unplayable.' Not a universal experience, of course, but we have one.
The game freezes about every other time it's suppose to load a scene or an area.
I believe you just claimed this one from above? Double counting doesn't improve your case. However, for the benefit of the doubt I'll give you points for two separate- corrupted save and loading issues.
To me this makes the game pretty much unplayable. I still consider myself one of the lucky ones in a very leaky boat since I can still get the game to run. I didn't bother specifying, yet again these issues since I have posted so many times in threads here and on the EA Forum. I felt that the best thing was to focus on problems that I know occurs across all platforms since that might be something BioWare is willing to deal with and address.
Your perspective is skewed. You are the unlucky minority in the leaky boat. Most people can get the game to run adequately.
Moreover, 'to me this makes the game pretty much unplayable' is an abuse of the language 'unplayable.' You gave two issues which prevented you from playing the game- loading and corrupted saves. The bugs may have ruined your enjoyment of the game to the point that you didn't want to play it, but calling it 'unplayable' as an objective fact when it isn't only undermines your credibility as a customer when raising issues.
Don't exagerate real things, or people will tune you out and ignore you.
And yes, I have cleared the cashe a number of times. It helps but after a while the problems return. I've also re-installed the game a bunch of times hoping that would help. It hasn't. My Xbox360 elite is as upgraded as it can possibly be and has the latest updates and no other problems. I've actually never had any issues at all other than the occational rare freeze in my other games.
That's a shame.
