mixing text spoken streams and white noise

[Andrea König]

Hi kapil,
many thanks for your reply. I run my pipeline with -v option and got the
following output:

/GstPipeline:pipeline0/GstAdder:mix.GstPad:sink1: caps = NULL
/GstPipeline:pipeline0/GstAdder:mix.GstPad:sink0: caps = NULL
/GstPipeline:pipeline0/GstAdder:mix.GstPad:src: caps = NULL
/GstPipeline:pipeline0/GstAudioConvert:audioconvert1.GstPad:src: caps = NULL
/GstPipeline:pipeline0/GstAudioConvert:audioconvert1.GstPad:sink: caps = NULL
/GstPipeline:pipeline0/GstWavParse:wavparse0.GstPad:src: caps = NULL
/GstPipeline:pipeline0/GstWavParse:wavparse1.GstPad:src: caps = NULL

Could you give a hint. Caps filter I set.
