Pausing audio that's not streaming

I’m working on a tutorial with a playback controller and voice-overs. I can only get it to pause when the voice-over audio is set to ‘streaming’. This is fine for the web, but I’m doing another version of this that will go on a cd, so I’d like the audio quality to be higher. I found that the quality is only higher if I choose ‘start’ instead of ‘stream’. But if I don’t use stream, then the pause doesn’t work. How would I get it to pause if it’s not streaming? Or how to I get better quality streaming audio? I’m trying different settings, but it doesn’t sound nearly as good as the non-streaming version.

Thanks
