==Squeezeslave Setup==
Here's how to setup squeezeslave to run on the core.  It's fairly straight forward.  One small issue is that because squeezeslave uses the OSS interface, you will need a separate sound card for each instance of squeezeslave you want to run.
===Download Source===
First download a version of [http://sourceforge.net/project/showfiles.php?group_id=105169 Squeezeslave].  I'm running the latest version as it fixed some playback bugs I was having, but any version that works with you're setup should be fine. 
===Installing=== 
*You'll want to put it somewhere in you're path.  
**Example: /usr/local/bin
====Modify /etc/rc.local====
Next add the following to /etc/rc.local (this is my setup for two)
  /usr/local/bin/squeezeslave -m 00:00:00:00:00:01 -o 0 -s -r &
  /usr/local/bin/squeezeslave -m 00:00:00:00:00:02 -o 1 -s -r &

* the MAC address can be whatever you want
* the -o option specifies which OSS output device ie /dev/dsp1
* the -s option tells squeezeslave to wait for a signal to quit rather than control-C
* the -r option tells squeezeslave to keep retrying to connect to the server, useful if the server is not running yet.
===Setting Up Alsamixer===
Next make sure all the volume levels in the mixer (alsamixer) are set correctly
  aslamixer
Make sure that the settings are as desired and save (Esc button)
===Setting Up LinuxMCE===

Next step, manually add the squeezeslave to linuxmce as a squeezebox using the mac address you gave it.  

====Select Device====
* Select '''Device->A/V Equipment'''
* Select SqueezeBox Player from the dropdown options
* Assign it to a room and entertainment area.  
* Regen your orbiters and reload the router.

== LMCE init script ==
Copy attached script text into a file named /etc/init.d/squeezeslave

===Make script executable===
 sudo chmod +x /etc/init.d/squeezeslave
===Modify Parameters===
Modify parameters in the beginning of the file to suite your needs. 
* MAC address
* slimserver host
* binary location
* soundcard device.

Below is the parameters you should change:

 NAME=squeezeslave
 DAEMON=/root/squeezeslave-0.7.1/$NAME
 DAEMON_ARGS="-o 1 -m 00:04:20:00:00:01 -r -s 192.168.80.1"

===Setup to Run at Start Up===
* Run from shell:

  sudo default-rd.d /etc/init.d/squeezeslave default 50

* You should now be able to start/stop squeezeslave from shell.
 
 sudo /etc/init.d/squeezeslave start

* Check with ps if it is running:
  ps aux | grep squeezeslave
**Example output:
 root      9007  0.0  0.3  64116  5436 ?        Sl   Jun18   0:03 /root/squeezeslave-0.7.1/squeezeslave -o 1 -m    00:04:20:00:00:01 -r -s 192.168.80.1

*To stop:

 sudo /etc/init.d/squeezeslave stop

* Restart your core and check if everything start as it should, including squeezeslave.

That should do it.
