Thank you for reporting this bug. This is very important for me.
I've tried to reproduce the bug in my Google Pixel 7, but I cannot reproduce the bug.
To make audio transport and remote control work, there are several things to check.
1. Everytime the web page refreshed, the page is muted, so we should clicked the UNMUTE button to hear sound.
2. Make sure "Tesla Display" app got the permission to record audio. Sometimes the app will not ask for permission even it does not own. I will fix this bug as soon as possible.
3. For remote control, I strongly suggest you enable the short cut for accessibility permission. After enabling the shortcut, you can know whether the accessibility permission for Tesla Display is enabled or disabled.
