autoaudiosrc : Failed to find a usable audio source

[hustxyj]

Hi all:

 

I installed both gstreamer-0.10 and gstreamer-1.3.2 on win xp.

I tried this command:

gst-launch-1.0 -v -m autoaudiosrc ! audioconvert ! audioresample !
autoaudiosink

whose output as below:

 

Setting pipeline to PAUSED ...

Pipeline is PREROLLING ...

When using the 0.10 version, everything worked fine.

Anyone can help?

Thanks!
