mixing text spoken streams and white noise

[Andrea König]

Hi Stefan,
many thanks for your help. I added capsfilter between audioconvert and
mix but still got the same error. If I run gst-launch with -v option the
caps properties are displayed. It seems there are the same caps for the
elements.

gst-launch -v adder name=mix  ! audioconvert ! lamemp3enc ! filesink
location=/test_noise.mp3  filesrc location="/whiteNoise-vol001.wav" !
wavparse ! audioconvert ! mix. filesrc location="/tmp_audio_0.wav" !
wavparse ! audioconvert ! mix.

/GstPipeline:pipeline0/GstAudioConvert:audioconvert2.GstPad:src: caps =
audio/x-raw-int, endianness=(int)1234, channels=(int)1, width=(int)16,
depth=(int)16, signed=(boolean)true, rate=(int)16000
/GstPipeline:pipeline0/GstAudioConvert:audioconvert2.GstPad:sink: caps =
audio/x-raw-int, endianness=(int)1234, channels=(int)1, width=(int)16,
depth=(int)16, signed=(boolean)true, rate=(int)16000
/GstPipeline:pipeline0/GstAdder:mix.GstPad:sink0: caps =
audio/x-raw-int, endianness=(int)1234, channels=(int)1, width=(int)16,
depth=(int)16, signed=(boolean)true, rate=(int)16000

FEHLER: Von Element /GstPipeline:pipeline0/GstWavParse:wavparse0:
Internal data flow error.
Zusätzliche Fehlerdiagnoseinformation:
gstwavparse.c(2091): gst_wavparse_loop ():
/GstPipeline:pipeline0/GstWavParse:wavparse0:
streaming task paused, reason not-linked (-1)

Can you tell me what goes wrong?

Thanks in advanced.
Best
Andrea
