audio engine failed to load error

Normally, I always use my earphone and my android k20. But I tweak some setting called "Resampler Type" to Sox. After listening of 20min I lost audio and can't even use speaker and microphone. How did this happen?

You are referring to Settings>Audio>Resampler and have changed this to SoX? This will provide a higher overall sound quality, but uses much more power (i.e. kills the battery quickly). Not sure how this would affect a microphone since Poweramp does not use that. And Using SoX for output on the device speaker is really not going to get you any benefit. I would change it back to the SW (software) driven format.
