hi

very thank , i will try this, only aquestion:
to coment the autodetec module what is the corret?

#.ifexists module-hal-detect.so
#load-module module-hal-detect
#.else
#load-module module-detect
#.endif

or 

.ifexists module-hal-detect.so
#load-module module-hal-detect
.else
#load-module module-detect
.endif

very thank

  Now as I understand it, when linux starts, 

  1) there is a program called hald (hardware abstraction layer daemon) that identifies the hardware attached to your computer.  In the output of aplay, each card is given an identifier...  "tarjeta {0 -3}"

  2) other programs like pa use the info hald provides to make decisions about how to use the hardware.

  In the case of tarjeta 2  - EWX2496  using the ice1712 driver (this same chip is in my tarjeta), apparently pulseaudio or hald did not identify it correctly, and when trying to connect to this tarjeta, pa realizes this and says no.

  The default global pa config file (/etc/pulse/default.pa) in ubuntu has these statements: 

  .ifexists module-hal-detect.so
  load-module module-hal-detect
  .else
  load-module module-detect
  .endif

  which is a means of auto-detecting the tarjetas on your system.  Let's change this:

  1) make a copy of your original global config file
      cd /etc/pulse/
      sudo cp default.pa default.pa.original

  2) comment out the lines that deal with auto detecting the tarjetas (the lines above)

  3) Add these lines in it's place:     sudo [vi,gedit,...] default.pa
  ------------
  # Load the devices:
  load-module module-alsa-sink sink_name=nvidia_out device=hw:0
  load-module module-alsa-source source_name=nvidia_in device=hw:0

  load-module module-alsa-sink sink_name=hdmi_out device=hw:1
  load-module module-alsa-source source_name=hdmi_in device=hw:1

  load-module module-alsa-sink sink_name=ewx2496_out device=hw:2 channels=10 channel_map=left,right,aux0,aux1,aux2,aux3,aux4,aux5,aux6,aux7
  load-module module-alsa-source source_name=ewx2496_in device=hw:2 channels=12 channel_map=left,right,aux0,aux1,aux2,aux3,aux4,aux5,aux6,aux7,aux8,aux9

  load-module module-alsa-sink sink_name=e192m_out device=hw:3
  load-module module-alsa-source source_name=e192m_in device=hw:3

  # Select default device
  set-default-sink nvidia_out 
  set-default-source nvidia_in
  ------------------------

  Note: We are telling pa to use devices identified by your system labeled hw:{0,1,2,3}... nothing special, except for the ewx2496 that uses the ice1712 device driver.  This is the same chip my tarjeta uses, and in that case I had to add extra information about the chip... the part that says "channel_map=..."  I'm not sure if the other tarjetas need special mappings or instructions, but give this a try.

  4) Restart pa ... in ubuntu, I would try "sudo /etc/init.d/pulseaudio {start,stop,...} and it would not give feedback if the server status had changed.  So I would use the pa manager (paman) to start/stop the pa server.  Frequently, I would not know if the server was still running and would use "ps aux | grep pulse" to check status.

  Let's see what happens

    2) Can you make sound with your speakers with pa and the cards that it does identify?
    yes i need to route the sound thru the no identified sound cards via PA

    when i por example, play a mp3, i can route via alsa the sound thru devices that no identified in PA, i am sure that card is runing correctly

    sorry and very thank
