Sending DTMF signal

[戚文敏]

Have you tried the following script:

gst-launch-1.0 audiotestsrc wave=0 ! audiomixer name=am ! autoaudiosink
audiotestsrc wave=8 ! am.

I use this script to test the audiomixer element. You can replace
audiotestsrc elements to your wave file src and your osxaudiosrc. And
replace the autoaudiosink to your alawenc...

Hope this will help you.
