Bluetooth devices must be paired to be seen by this app. Pair the devices using Android network settings before using this app for Bluetooth. Please read the manual before using: https://github.com/jroal/a2dpvolume/wiki/Manual .

Please post any issues to the issues list https://github.com/jroal/a2dpvolume/issues . I can only fix problems I know about and I need to know the details of the problems to fix them.

This app is free, open source, and contains no ads.

The "stored location" button will retrieve the location of the last Bluetooth device that disconnected while the service was running. Setting the preference "notify in foreground" and "start at boot" will ensure the service is running when needed.

Android 9.0 and up no longer need the media volume adjust feature as this is built into the OS. In fact, if you use the media volume adjustment feature of A2DP Volume it will fight with the volume adjust feature in the OS. Therefore the volume adjustment feature should not be used for Android 9.0 and up devices.

The text message reader can be tricky to set up. Here is some help: https://github.com/jroal/a2dpvolume/wiki/Reading-Messages
