java.io.IOException: bt socket closed, read return

Version

Media3 1.1.1

More version details

We are using media3 library to send voice commands to the media outlet. We noticed that sending voice commands to exo player works great if there are not bluetooth devices connected to the phone. However, if the user is trying to use a bluetooth speaker (or headphones) while using our app, the bluetooth seems to crash occasionally, and pause the background music. For example, user is using Spotify to listen to the podcast. Every once in a while, they receive a spoken voice command from our app (via exoplayer). Each time they receive a command the system successfully ducks the podcast, and then gives it focus once our app is done. However, after 10-25 mins of back and forth, the bluetooth seems to crash, and the Spotify podcast fails to resume once our app gives away focus. I see the following error in the logs:

Is there a way to figure out why is this crashing only when user has bluetooth connected?
