[pulseaudio-discuss] Help in setting up PA... SOLVED

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
load-module module-detect

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 

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
