Hi Nick, this sounds like the audio packet validation might be failing in the native Zune audio engine. This could be a bug in our audio packet validation code. Could you provide some details about the source audio such as the source audio format (mono/stereo, 8/16-bit) and the size of the audio data. One quick thing to try would be to check if the total size of the audio data is block aligned for the format (i.e. aligned to the WAVEFORMATEX.nBlockAlign value). We'll try to track this down asap here and if it's possible for you to share the source content that would be helpful too.

Thanks!
