I know endless_sleeper has already responded to you in another thread but I'm going to copy his answer here for anyone else having the same question:
"We know. Unfortunately, the only thing we (the contributors) can do is to disable the audio for audio exercises. (and forward it to the higher powers who may decide to do something about it but I wouldn't really count on it in the near future. ;) Sadly, disabling the audio exercises doesn't mean disabling the audio altogether. We apologize for the inconvenience."
