2017-08-21tests: Introduce audio tests, starting with HDMI signal integrityPaul Kocialkowski
This introduces a new test for audio going through display connectors. It currently contains a single subtest for HDMI signal integrity, but other test cases will be added later on. The test setup consists in using an HDMI-VGA bridge that separates the audio out (via a 3.5 mm jack) and feeding this back to the DUT's line-in where it can be recorded by ALSA with controls correctly configured. The audio test makes use of the audio and ALSA igt libraries helpers. Signed-off-by: Paul Kocialkowski <paul.kocialkowski@linux.intel.com> Reviewed-by: Lyude Paul <lyude@redhat.com>
