Maybe a step back.... I know a stream is active.. its volume is set to zero or its muted.... Is there anyway to tell if there is any data/sound being produced by the stream My current hack is to set the volume to 2% so I can still detect sound using pa_stream_peek Cheers jason taylor 2009/5/27 Lennart Poettering <lennart at poettering.net> > On Mon, 25.05.09 11:34, Jason Taylor (killerkiwi2005 at gmail.com) wrote: > > > I've worked around this by using xlib to grab the pid of the window > > application and that seems to work.. > > > > No applications seem to set xid yet that I can see (banshee, rythembox, > vlc, > > mplayer, totem etc) > > As mentioned libcanberra does.
