Remove all files except OWNERS.
This repository will be removed from the manifest change, but Treehugger
seems unable to test the manifest change, so this change first removes
all files so we can test that instead.

-//! Provides an interface for playing and recording audio.
-//!
-//! When implementing an audio playback system, the `StreamSource` trait is implemented.
-//! Implementors of this trait allow creation of `PlaybackBufferStream` objects. The
-//! `PlaybackBufferStream` provides the actual audio buffers to be filled with audio samples. These
-//! buffers are obtained by calling `next_playback_buffer`.
-//!
-//! Users playing audio fill the provided buffers with audio. When a `PlaybackBuffer` is dropped,
-//! the samples written to it are committed to the `PlaybackBufferStream` it came from.
-//!
-//! ```
-//! use audio_streams::{BoxError, SampleFormat, StreamSource, NoopStreamSource};

-//!
-//! let (_, mut stream) = stream_source
-//! .new_playback_stream(num_channels, sample_format, 48000, buffer_size)?;
-//! // Play 10 buffers of DC.

-Object Path /org/chromium/cras
-
-Methods void SetOutputVolume(int32 volume)
-
- Sets the volume of the system. Volume ranges from
- 0 to 100, and will be translated to dB based on the
- output-specific volume curve.
-
- void SetOutputNodeVolume(uint64 node_id, int32 volume)
-
- Sets the volume of the given node. Volume ranges from
- 0 to 100, and will be translated to dB based on the
- output-specific volume curve.
-
- void SwapLeftRight(uint64 node_id, boolean swap)
-
- Swap the left and right channel of the given node.
- Message will be dropped if this feature is not supported.
-
- void SetOutputMute(boolean mute_on)
-
- Sets the system output mute.
-
- void SetOutputUserMute(boolean mute_on)
-
- Sets the system output mute from user action.
-
- void SetInputNodeGain(uint64 node_id, int32 gain)
-
- Sets the capture gain of the node. gain is a 0-100
- integer which linearly maps [0, 50] to range [-40dB, 0dB]
- and [50, 100] to [0dB, 20dB],
- Default gain value is 50, which is 0dB.
-
- void SetInputMute(boolean mute_on)
-
- Sets the capture mute state of the system. Recordings
- will be muted when this is set.
-
- void GetVolumeState()
-
- Returns the volume and capture gain as follows:
- int32 output_volume (0-100)

-
- Returns information about nodes. A node can be either
- output or input but not both. An output node is
- something like a speaker or a headphone, and an input
- node is like a microphone. The return value is a
- sequence of dicts mapping from strings to variants
- (e.g. signature "a{sv}a{sv}" for two nodes). Each dict
- contains information about a node.
-
- Each dict contains the following properties:
- boolean IsInput
- false for output nodes, true for input
- nodes.
- uint64 Id
- The id of this node. It is unique among
- all nodes including both output and
- input nodes.
- string Type
- The type of this node. It can be one of
- following values:
- /* for output nodes. */
- "INTERNAL_SPEAKER","HEADPHONE", "HDMI",
- /* for input nodes. */
- "INTERNAL_MIC", "MIC",
- /* for both output and input nodes. */
- "USB", "BLUETOOTH", "UNKNOWN",
- string Name
- The name of this node. For example,
- "Speaker" or "Internal Mic".

- streams are 'fake' streams.
-
- void SetGlobalOutputChannelRemix(int32 num_channels,
- array:double coefficient)
-
- Sets the conversion matrix for global output channel
- remixing. The coefficient array represents an N * N
- conversion matrix M, where N is num_channels, with
- M[i][j] = coefficient[i * N + j].
- The remix is done by multiplying the conversion matrix
- to each N-channel PCM data, i.e M * [L, R] = [L', R']
- For example, coefficient [0.1, 0.9, 0.4, 0.6] will
- result in:

-CRAS = ChromeOS Audio Server
-===
-
-# Directories
-- [src/server](src/server) - the source for the sound server
-- [src/libcras](src/libcras) - client library for interacting with cras
-- [src/common](src/common) - files common to both the server and library
-- [src/tests](src/tests) - tests for cras and libcras
-- [src/fuzz](src/fuzz) - source code and build scripts for coverage-guided
- fuzzers for CRAS
-
-# Building from source:
-```
-# Generate install-sh
-./git_prepare.sh
-
-# Configure
-CC=clang \
-CXX=clang++ \
-CXXFLAGS="-g -O2 -std=gnu++11 -Wall" \
-CFLAGS="-g -O2 -Wall" \
-./configure --disable-alsa-plugin
-
-# Compile
-make -j$(nproc)
-
-# Compile with unit tests
-make -j$(nproc) check
-
-# Install binaries to /usr/bin
-sudo make install
-```
-
-## Code complete for for editors
-You need to install [bear] first and generate [compile commands] for
-[language server plugins in editors] by
-```
-make clean && make compile_commands.json
-```
-Then you'll get `compile_commands.json` for editor.
-Import the JSON file to your editor and you'll get useful code complete
-features for CRAS and its unit tests.
-
-# Configuration:
-
-## Device Blocklisting:
-
-Blocklist of certain USB output device(s) is possible by modifying the config
-file `/etc/cras/device_blocklist`.
-
-The format of this file is as follows:
-```
-[USB_Outputs]
- <vendor_id>_<product_id>_<checksum>_<device_index> = 1
-```
-Where vendor_id and product id are the USB identifiers for the card to
-blocklist. The checksum is the output of "cksum" command applied to the
-sysfs "descriptors" file of the device. The device index specifies the
-index of the output device in the card to blocklist. This is a bool
-parameter, so '= 1' enables the option.
-
-Example, blocklisting the non-functional output device reported by the C-Media
-based CAD-u1 mic:
-```
-[USB_Outputs]
- 0d8c_0008_00000000_0 = 1
-```
-
-## Card Configuration:
-
-There can be a config file for each sound alsa card on the system. This file
-lives in `/etc/cras/`. The file should be named with the card name returned by
-ALSA, the string in the second set of '[]' in the aplay -l output. The ini file
-has the following format.
-
-```
-[<output-node-name>] ; Name of the mixer control for this output.
- <config-option> = <config-value>
-```
-output-node-name can be speficied in a few ways to link with the real node:
-- UCM device name - The name string following the SectionDevice label in UCM
- config, i.e. HiFi.conf
-- Jack name - Name of the mixer control for mixer jack, or the gpio jack name
- listed by 'evtest' command.
-- Mixer control name - e.g. "Headphone" or "Speaker", listed by
- 'amixer scontrols' command.
-
-Note that an output node matches to the output-node-name label in card config by
-priorty ordered above. For example if a node has UCM device, it will first
-search the config file for the UCM device name. When not found, jack name will
-be used for searching, and lastly the mixer output control name.
-
-config-option can be the following:
-- volume_curve - The type of volume curve, "simple_step" or "explicit".
-- Options valid and mandatory when volume_curve = simple_step:
- - max_volume - The maximum volume for this output specified in dBFS * 100.
- - volume_step - Number of dB per volume 'tick' specified in dBFS * 100.
-- Options valid and mandatory when volume_curve = explicit:
- - dB_at_N - The value in dB*100 that should be used for the volume at step
- "N". There must be one of these for each setting from N=0 to 100
- inclusive.
-
-
-Example:
-This example configures the Headphones to have a max volume of -3dBFS with a
-step size of 0.75dBFS and the Speaker to have the curve specified by the steps
-given, which is a 1dBFS per step curve from max = +0.5dBFS to min = -99.5dBFS
-(volume step 10 is -89.5dBFS).
-
-```
