I am trying to set up the audio pipeline with audio_common following the steps in this tutorial.

When I try to test the audio pipeline with

gst-launch-0.10 alsasrc ! audioconvert ! audioresample ! alsasink

I get the following error:

ERROR: pipeline could not be constructed: no element "alsasrc".

During the audio-common download I recognised that gstreamer version 1.0 was installed (not 0.10), but the command above gives the same error, even with gst-launch-1.0.

Does someone have an idea how to solve this and make the pipeline work? Any comment would be appreciated!

Best Nina

Kind of. But I already had all plugins installed. I now installed sudo apt-get install gstreamer1.0-alsa and it seemed that the pipeline was setup properly. But still i cannot hear my microphone input through the headphones...

That would be a different (ie: new) problem then.

Exactly.. that's why I opened this one.

You need to change the pkg name as per the version you have. Last I checked, it worked fine with gst-launch-1.0 alsasrc ! audioconvert ! audioresample ! alsasink
