This patch includes automated test scripts for linux audio driver based on alsa-lib interface by using alsabat as test tool. It supports analog and display(HDMI/DP) audio test. The package needs the alsa-utils, alsa-lib installed environment. Signed-off-by: Focus Luo <focus.luo@linux.intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
