Streaming Audio driver on G120

Is there any RLP Streaming Audio driver for G120 out there? The GHI Audio.PlayPcm sound quality is too low for my work.

        private void PlayWav(string fileName)
            byte[] buffer = sd.LoadWave(fileName);
            Wave myWave = new Wave(buffer);
            Audio.PlayPcm(Cpu.AnalogOutputChannel.ANALOG_OUTPUT_0, buffer, myWave.Offset, myWave.Count, myWave.DataRate);

Yes, I’ve searched CodeShare. Unfortunately there is only RLP audio driver for EMX module.

Yes, certainly. But unfortunately, the author posted only efl file. Not the source code.
