Setting audio input source for Darkice using mixer: can't set vol??

am trying to set pcm or vol as the input source for my mixer in order to 
be used in conjunction with Darkice.

For Darkice I have already set input as /dev/dsp which should be ok as 
/dev/dsp0.0 comes up when using ls /dev..... however, I had this config 
working on another box so from what I can tell the 0.0 just gives the 
amount of simultaneous channels if I'm not mistaken.

The major difficulty however is coming from the fact that I can't set 
the rec input to be pcm or vol :-(

pciconf -lv shows this:

hdac0 at pci0:0:27:0:    class=0x040300 card=0x50038086 chip=0x3a3e8086 
rev=0x00 hdr=0x00
     vendor     = 'Intel Corporation'
     device     = 'HD Audio Controller'
     class      = multimedia
     subclass   = HDA

and as both Andrew Thompson and Frank Shute helped me last time getting:


into /boot/loader.conf audio works without any problem too as have 
tested playback!!

If I try to set:

# mixer =rec vol
mixer: unknown recording device: vol
usage: mixer [-f device] [-s | -S] [dev [+|-][voll[:[+|-]volr]] ...
        mixer [-f device] [-s | -S] recsrc ...
        mixer [-f device] [-s | -S] {^|+|-|=}rec rdev ...
  devices: vol, pcm, speaker, mic, mix, rec
  rec devices: mic, mix

I just get that the rec interfaces are mic or mix?? This is not the same 
as my other box using a different and much older integral sound chip.

I also attempted to comment the snd_hda_load out of /boot/loader.conf 
and include this instead:


which basically did the same thing as the above with (so also a small 
question here about which line is better?) so yeah am stuck with both 
kernel module loaders providing the same output :-(

Is there a way other then feeding a cable from the output into the input 
to rectify this issue??
