I've been building an android app that will output a single tone when opened (as a test for libpd), and I am encountering an error with OpenSL when I initialize and run PdService.initAudio and PdService.startAudio()

W/libOpenSLES: class OutputMix interface 0 requested but unavailable MPH=43
E/AudioTrack: AudioTrack::set : Exit

The speaker on the device turns on, and pops when I adjust the volume, but there is no audible tone. Any suggestions?

    Please share some of your code. Where you're trying to initialize the audio player – Reaz Murshed Jun 14 '16 at 11:25
  • I am having the same issue. I am using libpd for android and opening a patch file and sending some message to audio controller. App plays the sound for 4-5 seconds and then crashes the app with W/libOpenSLES: class OutputMix interface 0 requested but unavailable MPH=43 E/AudioTrack: AudioTrack::set : Exit – Alex Jun 22 '16 at 17:06
