Epulse

Software structure

What Epulse brings with:

• pulseaudio integration in ecore
• A gadget for enlightenment to control the volume of the desired backend
• A backend to abstract the sound manipulating from the ui
• Two backends, one for alsa, one for pulseaudio.

Feature Whishlist

To think about

• ALSA does not support event subscribing, so there should be something like a "ping" to the backend that the backend can refresh things like the cards etc.

What needs the backend

Events callled by the backend:

• sink_change
• sink_add
• sink_del

• playback_add
• playback_change
• playback_del

• source_change
• source_add
• source_del

• source_input_change
• source_input_add
• source_input_de

API for:
+ init()
+ shutdown()

+ volume_get(Sink):int
+ volume_set(Sink, Volume v)

+ mute_get(Sink):Bool
+ mute_set(Sink, Bool)

+ sink_default_name_support():Bool
+ sink_default_name_get():Sink
+ sink_default_name_set(Sink)

+ source_default_name_support():Bool
+ source_default_name_get():Sink
+ source_default_name_set(Sink)

+ change_sink_supports():Bool
+ change_sink(Playback, Sink)

+ change_source_supports():Bool
+ change_source(Source_Input, Source)

+ supports_change_output_device():Bool
+ channel_default_name_get(Sink):Channel
+ channel_default_name_set(Sink, Channel)

+ channels_get(Sink):Channel[]

structs:

Volume:

int channel_count;
int[] volumes;       <= the id of the array is the id of the channel and the value the volume

Sink

const char  *name;
void *b_data;

Playback

const char *name;
void *b_data;

Source

const char *name;
void *b_data;

Source-Input

const char *name;
void *b_data;

Channel

const char *name;
int idx;
