Hello. I'm playing Oblivion on m4 pro, crossover 25. It works great except audio. When any character starts talking the game freezes for 1 sec. In cities a lot of freezes. But it doesn't freeze when short phrases like "hello". I added overrides for libraries
x3daudio1_6
x3daudio1_7
xaudio2_6
xaudio2_6
But it didn't help.
