I am trying to use plug to play audio files that are S16_LE but my hardware only supports S32_LE. It is not working. Here is an example of the problem using speaker-test. First I use S32_LE and it works as expected. I then try S16_LE but it fails. Does this mean the plug plugin cannot convert between these sample formats?

Thanks, Adam
