hdaudio (experimental)
A device driver for the Intel HD Audio controller and speaker.
Currently, this driver is an experimental implementation and it just play a hard-coded sound data forever.
Building
You need a wav file (44.1kHz, 16-bits, 2 channels) to play. Generate a sound_data.h by wav2c.py:
$ cd servers/experimental/hdaudio
$ ./wav2c.py <your_wav_file>
Testing on QEMU
Enable the Intel HD audio device by HD_AUDIO:
$ make run HD_AUDIO=y
