GoKawiilAndroid Auto bug mutes notification sounds for some users
Users running Android Auto 17.9 and newer, including some on Android 17, are reporting that notification pop-ups appear silently, without any accompanying sound through their car's speakers. The app does briefly pause playing music as though attempting to play the alert, but no audio comes through. Reports affect both Pixel and Galaxy device owners, and one outlet says the problem also appears on Android Auto 18 and its 18.1 beta.
