bad commentay

Hi guys.
I play nba 2k14 on my Mac! It's all perfect , above your help.
One and only problem is thc commentary. It's distorted and with echoes. Can i install a new commentary mod?
Any suggestions?
Thanks

Do you have the Steam version of the game??

yes i have.

Then I'm not sure. Have never heard anything like this from somebody who bought the game.

What program read audio files in the game?
Presentations are good but commentary is very bad. Any Winetricks?

The sound in introducing videos and in the menu is good but not in the game.
