TMDXEVM8168: Problem in audio capturing and streaming in dm8168

Hello,

I would recommend you to verify the capture with arecord command first.
arecord -r 48000 | aplay -D plughw:0,1
refer https://linux.die.net/man/1/arecord


Yes, you could use gstreamer for audio capture and stream over network.
Here is example that you could try:
gst-launch alsasrc num-buffers=-1 ! 'audio/x-raw-int, endianness=(int)1234, signed=(boolean)true, width=(int)16, depth=(int)16, rate=(int)48000, channels=(int)2' ! alsasink device="plughw:0,1"
Alsasrc is used for capture alsasink is the audio sink.
For network streaming you must replace the alsasink element with udpsink or tcpserversink .
If you want to stream encoded file then you must add encoder ! parser before the streaming element.

Please note that in EZSDK the gstreamer version is 0.10.
Here is one useful command which you could use to check the elements:
For example gst-inspect | grep "enc" will print all elements that contains enc
But is you use gst-inspect "alsasink" this will print the full information of this element , this includes the properties that you could set.

Hello,

If you want to save the audio in file please replace ... ! alsasink with ... ! filesink location=xxx.pcm
Alsasink element renders audio samples not save in file.
