My Question or Issue
Using Spotify Connect to cast music to a Google Home speaker group, I am able to successfully connect and play music as designed. This allows me to change the volume of the speaker group using the Pixel 2 device volume keys, quickly skip a song, like a song, etc.
About 3-5 minutes with my phone being locked (screen off), the Spotify app will stop running in the background and the notification bar controls will disappear. This causes me to be unable to adjust the speaker group volume with the volume keys on my phone as well as unable to access the Spotify app notification shade controls (prev/pause/skip/like). I am unable to permanently restore the volume control unless I disconnect/reconnect Spotify Connect (volume key control only works in app). I am able to re-open the app, but I lose the instant convenience of adjusting the speaker group volume. The notification shade controls come back, but they again disappear after 3-5 minutes later when device is locked with screen off.
I have tried literally every troubleshooting technique including:
I left Google Play Music for Spotify Premium around December and never had this issue during the first month or so. I have tried other apps and other devices like an iPad and do not experience the same problem. This bug appears to be specific to the Spotify app running on a Google Pixel 2 device and casting to a Google Home speaker group. I have a friend with a Pixel 3A XL who also confirmed the same bug happens to him.
I've seen a few other reports of this issue in the Spotify message boards but nothing recent. Hopefully the Spotify Android dev's can show some love for us Pixel users 🙂
TLDR; When casting from a Google Pixel 2 to a Google Home speaker group, the Spotify app will stop running in the background after 3-5 minutes of the screen being off. Device volume up/down controls to adjust speaker group volume are permanently unavailable unless I disconnect/reconnect Spotify Connect.
