I have been playing on a cinema server for quite a while but recently after changing motherboards and reinstalling my OS (windows 7) I have had an issue with livestream.com were I am not getting any audio but the video is fine except for the ad when the stream is first added, the ad does not play, its just a spinning wheel. Also youtube and twitch seem normal. My livestream plays fine in the steam browser, chrome, and the menu where you add videos, but there is no audio when I add it to the theater. I have had this issue for 3 weeks and have not been able to find the source or a solution, so far i have tried...
reading the faq, I checked my volume mixer to make sure its not muted
reinstalling adobe flash player
running flash player debugger which shows an action script error when the stream is added
installing windows 7 codecs
running gmod on two other computers with completely different hardware, same problem
reinstalling gmod and steam

I ran out of ideas on what to try next, if anyone has had any similar issues or has an idea on what is going on help would be much appreciated. Thank You

So after a while it seems cinema must have updated and I now am getting audio just fine :D
Still not getting the ad for some reason though, and there seems to be a different issue with choppy video that everyone is having, but yeah.
