Microphone doesn't work in my own apps

Hello!
I installed Arch on my laptop few days ago and I wanted to continue my project (sound analyser). My app can't receive microphone input here (on desktop it worked ).
I had few problems with audio drivers here, but I wrote this modprobe.d file:

options snd-hda-intel id=PCH index=0
options snd-hda-intel id=HDA index=1

Since then all of my apps work with sound good. Even microphone input works in Audacity.

The problem is that microphone input doesn't work in my own app!
I tryed with portaudio and fmodex, but both have the same behaviour.
Getting devices in portaudio: (c++)

inputParameters.device = Pa_GetDefaultInputDevice();
    int count  = Pa_GetDeviceCount();
    for(int i=0; i<count; i++)
    {
        printf("%s \n",Pa_GetDeviceInfo(i)->name);
    }

output:

HDA Intel PCH: CX20757 Analog (hw:0,0) 
HDA Intel HDMI: 0 (hw:1,3) 
HDA Intel HDMI: 1 (hw:1,7) 
HDA Intel HDMI: 2 (hw:1,8)

dmix 

Default device can't catch anything.
As I said before: Audacity works.
