[Bug] Connecting or removing a Bluetooth causes the player to crash about flyleaf HOT 4 CLOSED

Hey @larsk2009, well nice research so far. Unfortunately, I know this kind of issue... I came across a lot times with NAudio. It happens when you initialize a NAudio player from one thread and dispose it from another. I was able to solve the most issue by switching to direct sound and creating the AudioMaster.cs to handle the device removal events etc. So, I guess the difference with the bluetooth device is that I'm missing/not handling properly an event on AudioMaster. I will need to find a bluetooth device for testing it tho.

Yeah I did check the events in AudioMaster.cs, and the OnDefaultDeviceChanged and OnDeviceRemoved events do get fired when the bluetooth device gets connected or disconnected. I do agree it seems like a threading issue.

To make matters worse, I actually found with more testing that the issue happens every time when disconnecting the device, but only sometimes when connecting it.

Hey, as I don't have a bluetooth adapter and device to test if you want try to... test if initializing and disposing happens at the same thread... and if that's the problem.

AudioPlayer.cs:Initialize()

Log($"AudioPlayer initializing on thread {System.Threading.Thread.CurrentThread.ManagedThreadId}");

AudioPlayer.cs:Dispose()

if (player != null) Log($"AudioPlayer disposing on thread {System.Threading.Thread.CurrentThread.ManagedThreadId}");

I get different threads but Dispose is not hanging... maybe it is happening only for the bluetooth device.

I might have to create a thread only for all the naudio players for initializing/playing/disposing at the same thread. I'm afraid that it causes other issues as well. By looking at naudio's issues you will see a lot similar. Seems to be an issue with COM objects.

Should be fixed in v3.4.2. I wasn't able to test it so let me know if still not working!
