Summary

Replaces the catch-all catch (Exception) { } swallow pattern in AudioCaptureBase.Dispose(bool) and AudioPlayback.Dispose(bool) with a narrower set of catch clauses, so unexpected failures inside Unprepare() show up in dlog instead of disappearing.

Changes

• src/Tizen.Multimedia.AudioIO/AudioIO/AudioCapture.cs (Dispose(bool), around L131)
• src/Tizen.Multimedia.AudioIO/AudioIO/AudioPlayback.cs (Dispose(bool), around L168)

For both files the previous block:

try
{
 Unprepare();
}
catch (Exception)
{
}

is now:

try
{
 Unprepare();
}
catch (ObjectDisposedException)
{
 // Expected during shutdown races.
}
catch (InvalidOperationException)
{
 // Expected if the underlying handle has already been torn down.
}
catch (Exception ex)
{
 Log.Error(GetType().Name, $"Unexpected error during Dispose: {ex}");
}

ObjectDisposedException is listed first because it derives from InvalidOperationException (C# requires the more-derived catch first).

Behavior & API Compatibility

Verification

• Build: dotnet build src/Tizen.Multimedia.AudioIO → 0 errors, 0 new warnings
• Tests: N/A — no behavior change for the documented contract; existing AudioIO tests remain valid
• Benchmark: skipped — change is on the dispose path, not a hot path, and only adds error-path logging. No sdb device available in this environment for runtime measurement.
