* ## Module Options
|
||||
*
|
||||
* - `driver.mode`: the driver mode, sink|source|duplex, default duplex
|
||||
* - `midi.ports`: the number of midi ports. Can also be added to the stream props.
|
||||
* - `ffado.devices`: array of devices to open, default hw:0
|
||||
* - `ffado.period-size`: period size,default 1024
|
||||
* - `ffado.period-num`: period number,default 3
|
||||
* - `ffado.sample-rate`: sample-rate, default 48000
|
||||
* - `ffado.slave-mode`: slave mode
|
||||
* - `ffado.snoop-mode`: snoop mode
|
||||
* - `ffado.verbose`: ffado verbose level
|
||||
* - `latency.internal.input`: extra input latency in frames
|
||||
* - `latency.internal.output`: extra output latency in frames
|
||||
* - `source.props`: Extra properties for the source filter.
|
||||
* - `sink.props`: Extra properties for the sink filter.
