Can't redirect microphone via xfreerdp

I use UBOX R89(rk3288 Cortex-A17) with installed “Ubuntu firefly” and usb audio card. I installed there freerdp and try connect to windows 7 Ultimate host using

xfreerdp -x l -a 32 --rfx --no-tls --no-nla --plugin cliprdr --plugin rdpsnd --data alsa latency:50 -- --plugin drdynvc --data tsmf:audin:alsa -- --ignore-certificate -u administrator 192.168.x.x

My .asoundrc :

pcm.!default {type hwcard 3}ctl.!default {type hwcard 3}

In the Ubuntu host microphone working fine, in the windows host remote audio recording device displayed but not working.I must use only ALSA because pulseaudio not working.No errors displayed in Ubuntu. Do you have any idea about this problem?

What is UBOX R89?also is a developer board?
