sure.
The SDP I send looks like:
v=0
o=VDP 1097139000 1097144000 IN IP4 192.168.0.1
s=VDP DEMO
t=0 0
m=video 8888 RTP/AVP 34
c=IN IP4 192.168.0.1
a=rtpmap:34 H263-2000/90000
a=cliprect:0,0,576,704
m=audio 8890 RTP/AVP 14
c=IN IP4 192.168.0.1
b=AS:96
a=rtpmap:14 MPA/22050/2


The video is shown just fine (besides some timing issues - see other
post) but the audio is completely ignored. I can see in wireshark that
vlc does in fact get the audio data but it does not recognize it.
