Play audio synced with timeline and be able to start audio from in between

Heyo!

I have the following issue:

I'm animating a video for a song of mine and imported it to Animate. 
First problem is, that while playing the Animation inside the timeline where it is slower than in the real performance the music is not slowed down, so i cannot say where i am for real in the song. My Song is running away..
I noticed this while using "test movie", where the video of course moves much faster.

Second thing is that i havent found a way to be able to start the audio file like from minute 1 and secong 25 or whatever. I always have to play it from the beginning which of course is no option. The song is like 7 minutes.

Can anyone pleeease help me to solve that problem? By the way i am new to adobe animate, so maybe the answer is quite simple.

THX so far!!
