button deactivate hover effect

Hello,
I made a sound button but it deactivated my hover effect of my hyperlink icon.

I got a task that I have to insert click sound in an interactive PDF document. I designed the document in Indesign and made a hyperlink icon in Indesign, which I also embedded a hover effect. Because the Media panel in Indesign has bugs (my other classmates are dealing with the same bugs too), so in Acrobat Pro I created a button and input the sound file (I tried both AIFF and WAV file). The sound worked well. However, it deactivates the hover effect at my hyperlink icon. My hyperlink icon just doesn't change color when hover the cursor on it anymore. Can anyone please help me to include the sound, but still keep the hover effect works? 

The table of content icon should turn to white when hover mouse on it (like the full-screen mode), but it doesn't
Thank you!
