Hello,<br>
<br>
I am trying to write a program which sends data into left speaker while<br>
the right one remains silent. The obvious way would be to set up a<br>
stereo pipeline and send the bytes in this order<br>
<br>
left data, zero, left data, zero, left data, zero, etc.<br>
<br>
but ... is there a better way? Can I join my data with silence using<br>
interleave? Silence can be generated by "audiotestsrc wave=4", so ...<br></blockquote><div><br>I didn't understand clearly what you're trying/wanting to do, but you might be interested in the audiopanorama element.<br>

<br>
For testing, I try to play sine wave from one channel only:<br>
<br>
gst-launch interleave name=i ! audioconvert ! gconfaudiosink \<br>
audiotestsrc ! capsfilter \<br>
caps=audio/x-raw-int,rate=44100,channels=1,depth=16,signed=true \<br>
! queue ! i.sink0 \<br>
audiotestsrc wave=4 ! capsfilter \<br>
caps=audio/x-raw-int,rate=44100,channels=1,depth=16,signed=true \<br>
! queue ! i.sink1<br>
<br>
But I get this error message:<br>
WARNING: erroneous pipeline: could not link queue0 to i<br>
<br>
Thank you for help in advance,<br>
