python-pulse-control (original) (raw)

Hi there. Thanks for this library! I've been looking for something like this, and am extremely grateful that someone has put in the hard work to make it possible.

I am interested (it seems) in a feature that isn't present in your wrapper, or perhaps it isn't present in libpulse...

When I use pacmd, and list-sinks, I get output like this:

2 sink(s) available.

And doing pulse.sink_list() gives me a python list representation of this (awesome!). But if I inspect one of the sink objects, I get fewer attributes:

s.c_struct_fields      s.index                s.port_active
s.channel_count        s.latency              s.port_list
s.channel_list         s.monitor_source       s.proplist
s.configured_latency   s.monitor_source_name  s.sample_spec
s.description          s.mute                 s.volume
s.driver               s.name                 
s.flags                s.owner_module

In particular, I'm looking for "state: RUNNING", "suspend cause:"... I'd like to write some code that detects when sound is flowing, or at least when PA thinks it hasn't and has therefore suspended a sink.

Am I missing something?

Thanks again!
