--- Comment #5 from Ethan Lee flibitijibibo@gmail.com --- The ones that can be ignored will look like one of these two, both are "possibly lost" messages:
1. at notify_alloc by RtlAllocateHeap by create_voice by IXAudio2Impl_CreateSourceVoice/CreateSubmixVoice
2. at notify_alloc by RtlAllocateHeap by get_tls_data by winetest_set_location by IXAudio2VoiceCallback_*/IXAudio2EngineCallback_*
I believe the rest are valid errors.
