This new test ensures DisplayPort audio works by using the Chamelium.
It enables the DisplayPort output and sends an audio signal containing a set of
frequencies we choose to all HDMI/DisplayPort audio devices. It starts
recording audio on the Chamelium device and uses the stream server to retrieve
captured audio pages. It then checks that the capture audio signal contains the
frequencies we sent, and only those, by computing a FFT.
A new library has been added to libigt to communicate with the stream server.
It implements a simple custom TCP protocol.
In case the test fails, a WAV file with the captured data is saved on disk.
Right now the test has a few limitations:
- Only the first channel is checked
- IGT only generates audio with a single sampling rate (48 KHz)
- Audio data is not captured in real-time
These limitations will be lifted in future patches.
PulseAudio must not run during the tests since ALSA is used directly. To ensure
this, edit /etc/pulse/client.conf and add `autospawn=no`. Then run
`pulseaudio --kill`.
This commit deletes the existing audio tests. They weren't run and required an
exotic configuration (HDMI audio splitter, dummy HDMI sink and a line-in port
on the DUT).
This patch also changes lib/igt_audio to use uint16_t instead of short. The
rationale is:
- The standard says a short is at least 16 bit wide, but a short can be
larger (in practice it won't happen, but better use types correctly)
- It makes it clearer that the audio format is S16_LE, since "16" is
in the type name.
This patch depends on the following Chameleon bugs:
- https://crbug.com/948060
- https://crbug.com/950857

-Audio Support in IGT
-====================
-
-This document provides information and instructions about audio support in IGT.
-
-Introduction
-------------
-
-The audio test is aimed at testing the audio features of display connectors,
-such as HDMI.
-
-Test setup
-----------
-
-The setup required for the audio test consists of using an HDMI-VGA adapter with
-an audio-out 3.5 mm jack to extract the audio from the HDMI interface.
-The audio-out jack is connected back to the device-under-test's line-in.
-
-Depending on the behavior of the adapter, it may be necessary to connect a
-ghost VGA dongle to it (in order to emulate a connected display) to enable the
-audio output. There are guides available detailing how to build these.
-
-When executed, the test will automatically send the test audio signal to all
-ALSA audio HDMI outputs and record from the standard ALSA capture device.
-
-Configuration
--------------
-
-In order to deploy the test, ALSA controls have to be configured to set the
-ALSA capture source to line-in. On Intel x86 systems, this can be achieved
-with the following calls to the amixer utility:
-# amixer sset Line 31 on
-# amixer sset "Input Source" Line
-
-It is then useful to store the ALSA state permanently with the alsactl utility:
-# alsactl store
-
-These settings can be restored with the alsactl utility:
-# alsactl restore
-
-It is desirable to ensure that the alsa-restore and alsa-state systemd services
-are enabled to do this job automatically, especially in the case of an
-automated testing system:
-# systemctl enable alsa-restore
-# systemctl enable alsa-state

The process requires the Chamelium to be connected to the Internet to succeed.
+Audio Capture
+-------------
+
+The Chamelium supports audio capture. IGT tests take advantage of the
+Chamelium streaming server to download audio samples from the Chamelium.
+
+IGT needs direct access to audio devices through ALSA, so PulseAudio needs to
+be stopped (otherwise audio tests will automatically get skipped). To make sure
+PulseAudio isn't running:
+
+- Edit /etc/pulse/client.conf and add autospawn=no
+- Run `pulseaudio --kill` (if it succeeds, it means PulseAudio was running)
+- Make sure a DE that automatically spawns PulseAudio isn't running
+
+In case a test fails, the raw captured audio files will be dumped in a WAV
+file.

Before this patch, the audio test first sends an audio signal for 2s, and then
checks whether the captured signal matches.
This patch makes it so we send and check the signal in parallel. Thus we can
stop the test as soon as we receive the correct signal. This saves ~2s per
audio test.

Most people don't have "remember what the last two parameters of
snd_pcm_set_params are" in their lifegoals list. Use variables so that it's
clearer what those are.

This commit updates the audio test to make sure we receive a signal from both
audio channels. However this commit doesn't check that left and right channels
are not swapped. Such a check requires some more work (because the Chamelium
device does swap left and right channels) and will be implemented in a future
commit.
This commit adds a new channel argument to audio_signal_add_frequency, to add
a frequency to a single channel only.
Some light refactoring has been performed: a proper audio_signal_fini
function has been introduced and size_t in now used when it should be.

Send a different signal to each channel and make sure captured audio channels
are not swapped or mixed up.
The Chamelium device has a bug and already swaps the left and right channels.
For this reason, clients need to retrieve the Chamelium channel mapping and
accomodate for this. See https://crbug.com/950922 for a discussion about this.

The audio test is now run multiple times with a variety of playback sampling
rates.
We now query the capture audio format from the Chamelium XML-RPC API instead of
hardcoding it.
One limitation is that we need to start sending an audio signal before being
able to query the capture audio format. However we need the capture sample rate
to decide which frequencies we generate. For now we use the playback rate and
check that it's the same as the capture rate.
Another limitation is that the DP receiver reports an unknown sampling rate
during the 44.1KHz test. In this case we assume the capture rate is the same as
the playback rate. We'll fail later anyway if this assumption is incorrect
since we check the signal we receive.
