SCORouting to PCM in Desktop

Hello ,

I have query  for HFP in bluez.
As we know in Desktop PC ,  SCORouting is default routed to HCI and I
used to get sco data on HCI.
But is there anyway to route it to my desktop PCM.

I can't use audio.conf file(available at  /etc/bluetooth) as in my PC
dbus is having some problem.
Apart from that is their any option so that it could be changed to PCM
 either by doing any tweak to bluez user space or kernal space?

Any help is welcome.
