DR17B8. No sound on TL

Hey guys. straight to the point. After a 4-5 min editing, audio stop playing back (Not issue on beta 7 this is from 8 on window, MAC's version is good)

Curios thing is on media pool I have playback but when I put the clip on any TL it wont play it back.

Cheers...

I went back to BETA7 and now I have same issue on that version. Lol... So sad....

What's your audio hardware?

What settings under Preferences>System>Video and Audio I/O>Speaker Settings?

Thank. The problems just dissapair with beta9 but fusion issues appear.

I am on window. Mac book Pro works perfect.
