[gst-devel] could not link audiotestsrc0 to jackaudiosink0

[patrick]

hi,

i was trying this command but got an error:
gst-launch-0.10 audiotestsrc ! jackaudiosink
WARNING: erroneous pipeline: could not link audiotestsrc0 to jackaudiosink0

using alsasink is working (i can hear a tone). why it's not working with 
jack audio connection kit. but this command works:

gst-launch-0.10 filesrc location=/home/pat/test2.ogg ! oggdemux ! 
vorbisdec ! audioconvert ! jackaudiosink
