I have something toggles off/on and not sure what I did?
When I insert a clip into my time line I don't get the audio.

However, if I add a new timeline then all is well.

Something is turned off and not sure what it is?

Whoooooopss.
I see what I did wrong..

It would be good if you could tell us what that was so as to help others who might have the same problem...

You probably targeted a wrong track, or...?

The Premiere Pro source monitor window has an icon (bottom right of its icon strips) that toggles audio + video, video only, audio only.

See this livedocs link (http://livedocs.adobe.com/en_US/PremierePro/3.0/help.html?content=WS1c9bc5c2e465a58a91cf0b1038518aef7-7d23.html). Click around the "Assembling a sequence" links on the left for more related info.

Mike, this has nothing to do with Guy`s problem. He said it worked when he created a new timeline. Source toggle works project-wide.

But thanks for your info anyway.

Ah, I missed that crucial sentence.

Maybe the audio tracks were deleted from the old timeline? I guess we may never know!
