AudioOutput selection in case only SmartWatch was previously connected to Android Device is broken.

Describe the bug
On devices that have problems with only SmartWatch connected currently we see infinite loop of connection attempts (disconnected => connecting => connected => disconnected => ....) to SmartWatch device during the conference.
This blocks us from selecting another AudioOutputs as system constantly tries to redirect audio to Bluetooth device.
For user it looks like voice interruptions during audio/video conference or sometimes no audio output at all.

If only SmartWatch connected w/o any other bluetooth headset - audio output selection does not work on most devices.
If SmartWatch connected with other bluetooth headset connected - audio output selection works on most devices.
Only Bluetooth headset connected (w/o SmartWatch). Audio output selection works good on most devices. (On Samsung A51 Android 11 we can't select Wired headset, but switching between BT and Speaker works stable.)

To Reproduce

modify app to listen for AudioManager.ACTION_SCO_AUDIO_STATE_UPDATED with BroadcastReceiver, log AudioManager.EXTRA_SCO_AUDIO_STATE to logcat.
Pair & Connect SmartWatch device to Android phone.
Disconnect & Forget/Unpair any other audio devices from Android phone
Force stop & clear data of App(which used with AudioSwitch audio output selection)
Restart/Reboot Android phone
Wait for Android system start and verify that SmartWatch device connected to Android phone
Launch App and proceed to Audio/Video conference
Listen to Audio from SmartWatch (silent) and Android Phone (audio with interruptions)
Check logcat for AudioSwitch & BluetoothSCO status updates.

Expected behavior
SmartWatch device is ignored and blocked from connection to AudioOutput. Audio/Voice routed to WiredHeadset(if connected) or to Speaker. No audio/voice interruptions during conference.

Actual behavior
Audio/Voice interruptions and infinite loop of SmartWatch connection attempts to AudioOutput.

AudioSwitch Version

Version: 1.1.2

Android Device (please complete the following information):

Device: HTC U12+, Android 9 (Pie). API Version: API 28.
SmartWatchDevice: Samsung Galaxy Watch Active2(7A0F), SM-R830, Tizen 5.5.0.2

Screenshots
Not available

Additional context
Devices we checked with SmartWatch problem:
Pixel 3a, Android 11 - Even connecting normal BT headsets not helping in any way, still broken sound output.
Xiaomi RedMi Note 9 Pro, Android 10 - After connecting normal BT headset - phone is able to differentiate and ignore SmartWatch device in some way.
Samsung A51 Android 11. It works very stable. Maybe because of Samsung Galaxy Watch Active 2 we used for testing. We still not sure how Samsung Android devices will behave with another SmartWatches made not by Samsung.

This is what we found at the moment.

Thanks @Alton09.

Looks like problem was caused by 3rd party code, and there is low probability to catch such combination in real life :)
I think there is no changes needed to AudioSwitch library.
Later I'll update with more info.

Answer 2 · 2021-06-23T08:33:38.000Z

Yes. Problem was in 3rd party code that don't have filtering of Bluetooth devices and it's entered into infinite loop of connection tries to SmartWatches.

Sorry for spent time.

No worries @VitaliyHTC ! Thanks for the additional info and closing this issue
