You can do that by interleaving the 2 audios into a single stream and
playing it as usual.

Use something like:

uridecodebin ! audioconvert ! audioresample ! capsfilter
caps="audio/x-raw-int, channels=1" ! ...

to convert a multiple channel input into a single channel.

Then link 2 branches like that into a interleave element.
You should have something like this:

uridecodebin ! audioconvert ! audioresample ! capsfilter
caps="audio/x-raw-int, channels=1" ! queue ! ileave. uridecodebin !
audioconvert ! audioresample ! capsfilter caps="audio/x-raw-int,
channels=1" ! queue ! ileave. interleave name=ileave ! queue !
audioconvert ! autoaudiosink

Hope this helps.

PS.: please add a subject to your emails
