Could you restate your question?
Photoshop Elements 13 and Premiere Elements 13 are standalone programs which can integrate in several regards once installed on the
same computer. It is not clear how you expect to get sound in Premiere Elements 13 from a tryout version of Photoshop Elements 13. That is the
way I am reading what you wrote.
By any chance are you trying to get Premiere Elements 13 to work for you and you keep getting an error message about "Failed to create Conexant Audio Factory...."?
If so, please read the following which may give you some answers on the subject
Also, please explore Premiere Elements Edit Menu/Preferences/Audio Hardware ASIO settings Input and Output.
If none of the above applies to your situation, then more details and clarification please on your situation.
