I just got a 2018 Subaru Outback. Ive paired it with my Pixel 2XL. I also have Android Auto installed on my phone. I can hear sound for maps and Amazon music over the car speakers, but no matter what I do, I can't seem to get the sound working for my Google Play music. It shows all my music and I can start and and pause the songs, but there is never any sound. Everything else seems to work fine. I can hear my phone calls. I am so sad that I can't hear my own music. Anybody else have this problem? How do I fix it?
