Pipeline works in linux but not in widows

Being a bear of little brain (Winnie thur Poo) …
I’ve got a pipeline that wotks in linux. I changed the sink:

gst-launch-1.0.exe -vc udpsrc multicast-group=224.1.1.1 auto-multicast=true port=5000 caps=“application/x-rtp, media=(string)audio, clock-rate=(int)8000, encoding-name=(string)PCMU, payload=(int)0, ssrc=(guint)1350777638, clock-base=(guint)2942119800, seqnum-base=(guint)47141” ! queue ! rtppcmudepay ! mulawdec ! autoaudiosink

And get, the bits I don’t understand are -4 and Interal stream error

Can anyone help please?

placing audioconvert ! audioresample between mulawdec and autoaudiosink might be able to solve the not-negotiated error.

I was ready to throw in the towel and tell my customer “windows is too hard” but your solution works a treat. Thank You.
