I'm running a basic application on Orange-Pi DVK with Gstreamer-1.4.0. While running the application it throws this error:

AL lib: (WW) alc_initconfig: Failed to initialize backend "pulse"
AL lib: (EE) ALCplaybackAlsa_reset: snd_pcm_hw_params(self->pcmHandle, hp) failed: File descriptor in bad state

While running on Ubuntu (running on VMware), it works well. Why is this not running properly on the Development kit (Orange-Pi) and how can I resolve this?

These 2 forum threads sound like your issue:

The resolution there was to install Pulseaudio:

$ sudo apt-get install pulseaudio
