AudioOutputExample fail on Ubuntu 14.04 LTS

Hi Arturo!

Ok, i check my sound card,

aplay -l

**** List of PLAYBACK Hardware Devices **** 

Card 0: HDMI [HDA
Intel HDMI], peripheral 3: 0 HDMI [HDMI 0] 

   Sub-Device: 1/1 
   Subdevice # 0:
subdevice # 0 

Card 0: HDMI [HDA
Intel HDMI], peripheral 7: 1 HDMI [HDMI 1] 

   Sub-Device: 1/1 
   Subdevice # 0:
subdevice # 0 

Card 0: HDMI [HDA
Intel HDMI], peripheral 8: 2 HDMI [HDMI 2] 

   Sub-Device: 1/1 
   Subdevice # 0:
subdevice # 0 

Card 1: PCH [HDA
Intel PCH], device 0: ALC668 Analog [ALC668 Analog] 

   Sub-Device: 1/1 
   Subdevice # 0:
subdevice # 0

If my sound card (PCM?) is ALC668 Analog i should target on Card 1
As i rode , device selection could performed by file /etc/asound.conf:

pcm.!default {
 type
 hw
 card 1
}
ctl.!default {
 type
 hw           
 card 1
}

Then i reboot to check if any change and call :

aplay-l

It seems asound.conf not working or i'm probably wrong somewhere..

I also tryed to set device by adding in /etc/modprobe.d/alsa-base.conf,

at the end :

options snd-hda-intel model=pch position_fix=1

Still no success

How would you set manually the deviceID ?
