THIS BECOMES UNBEARABLE: voice audio won't render

I know this problem has been posted here for a while now but I don't understand, why Adobe doesn't do anything??? 

It's a bug in the software, not my computer. I've been using Rush on my Windows and then I switched to Mac. And it's the same!!! I have to render videos MORE THAN 5 TIMES to get a video with the audio! This is so stupid! I have voice audio and music audio. Music audio is always there after render but the voice is not.

ADOBE, WHY DON'T YOU DO ANYTHING? 

I'm literally crying, it takes way too much time. The time I spend on 5-6 renders I could edit a few videos....
