I’m surprised there isn’t support for m4b. Seems like something that could be implemented. Disappointed that it’s not as now I have to use a different app for my audiobooks. So much for being able to control the system through one app.

Welcome, thank you for reaching out to Sonos Community, I totally understand where you're coming from and I’m here to help.
Here are the current support audio formats for Sonos.
I'll submit a feature request to add .m4b to our development team. We don't have a timeline we can share for this feature, but we'll be sure to make an announcement if we have any updates.
If you need help with any other information, please be sure to let us know.
