No audio when duplicate stream

[bigP]

Hi.
I try to stream TV channels from my dvb-t card, It works fine when I stream one channel like this on command line:

vlc --intf telnet --color --ttl 12 --ts-es-id-pid dvb-t://frequency=000000000 --program=2201 :sout=#transcode{vcodec=h264,vb=400,fps=24,scale=1,width=400,height=300,acodec=mp4a,ab=100,channels=2,samplerate=44100}:udp{mux=ts,dst=127.0.0.1:1234}

but when I try to stream more than one channel I get only video

vlc --intf telnet --color --ttl 12 --ts-es-id-pid dvb-t://frequency=000000000 --programs=2201,2203 --sout-transcode-audio-sync --sout-standard-access=udp --sout-standard-mux=ts --sout=#transcode{vcodec=h264,vb=400,fps=24,height=250,width=300,acodec=mp4a,ab=100,channels=2,samplerate=44100}:duplicate{dst=std{dst=127.0.0.1:1234},select='program=2201',dst=std{dst=127.0.0.1:1235},select='program=2203'}

Could any body help me to resolve that problem. Please!
Thank you very much!
