Discovered mixer doesn't support targetdataline settings #14

What steps will reproduce the problem?
1. Create decoder channel with mixer source, using Left, Right, or Mono

When loading the windows batch file I get the following:

Code:
********** Configuring USB Tuners **********
Tuner Manager - discovered [0] USB tuner devices

could not load 'loading.png'
Starting the main gui
MixerManager - loading system mixer devices

        [NOT LOADED] Mixer:Port Microphone (2- High Definition  - audio format n
ot supported
        [NOT LOADED] Mixer:Port Line In (2- High Definition Aud - audio format n
ot supported
I then have the following 'Mixer' options when selecting source 
'Mixer/Soundcard':

'Line In (2 - High Definition Aud'
'Microphone (2 - High Definition'
'Primary Sound Capture Driver'

(Note this is a desktop computer with two microphone inputs, front and back.)

When selecting either 'Line In' or 'Microphone', I get the following output in 
the Cmd window:

Quote:
ERROR: ComplexMixerSource - mixer target data linenot available to read data 
from - line with format PCM_SIGNED 48000.0 Hz, 16 bit, mono, 2 bytes/frame, 
little-endian not supported.
I guess this explains why my decoder just sits there at an 'IDLE' state when 
trying to decode anything. Any idea what might be up?

UPDATE: I have checked this on both my desktop and laptop and gotten the same 
ComplexMixerSource error.

Restructured the mixer/sound card code to test both mono and stereo on every 
mixer and only allow user to select the supported channels for each mixer.
