Some web sites can not listen to music. I'm not sure an associated with Adobe? How do I know?

In addition to the website, can you give an example of the applications you might have open at the time?

I just read this question, and realized that I may have had a similar issue.

I am running Win 8, and had Premiere Pro CC 2014 open.

I reconfigured the audio hardware / output

I couldn't hear YouTube  (but I could hear Spotify) ?

I had Spotify launched before I opened Premiere Pro.

I will try to run a test to:

- Update to PremierePro CC 2015

- Change the audio mapping

- Launch Youtube before Pr.

I don't have this issue on my macbook pro.

Can you give any examples of what you are referring to? I am not sure what you are asking.
