Use the stora as a soundproxy

This is a work in progress and does not work yet!!!!!


Please note: this tutorial is intended for debian users!

Lets suppose you have already bought a linux compatible sound card. Now you have to make shure the kernel has the appropriate modules compiled in. If you plug in the sound card lsmod | grep snd shound show some modules. If not you'll have to substitute the kernel (or compile the appropriate module).

Install the kernel

You have two option: eighter compile the kernel by yourself or use a precompiled one.

You can download a precompiled kernel here:

TODO: Add a link to the kernel.

Then put the kernel package somewhere on the stora.

Get the stora flash utility: 

wget http://dl.dropbox.com/u/1397036/stora_di/stora-flash

And install the kernel: 

sudo dpkg -i kernel-package-name.deb
cd /boot
/path/to/stora-flash -i vmlinuz-kernel-name -r initrd.img-kernel-name

Install/configure Pulseaudio

Unfortunately the RTP module in version of pulseaudio currently shipped with debian is buggy. We'll need to compile pulseaudio on our own.

On the stora do: 

sudo apt-get update
sudo apt-get install make build-essential pulseaudio
sudo apt-get build-dep pulseaudio
wget http://0pointer.de/lennart/projects/pulseaudio/pulseaudio-0.9.22.tar.gz
tar -xfz pulseaudio-0.9.22.tar.gz
cd pulseaudio-0.9.22
./configure CFLAGS=-march=armv5 #The processor in the Stora is a ARM V5. 
make
sudo make install

Unless you have pulseaudio verison 0.9.22 on your system, do the same on your host system but without the -mach=armv5 parameter.

On the stora edit both, /etc/pulse/system.pa and /etc/pulse/default.pa and uncomment or add the following line: 

load-module module-rtp-recv

On the host system edit /etc/pulse/default.pa and change the lines: 

#load-module module-null-sink
#load-module module-rtp-send

To: 

load-module module-null-sink sink_name=rtp format=s16be channels=2 rate=44100 description="Stora"
load-module module-rtp-send source=rtp.monitor

Tell the stora to load pulseaudio at startup 

sudo update-rc.d pulseaudio default

Restart pulseaudio on both the Stora and on your host system: 

sudo killall pulseaudio
sudo service pulseaudio start

On the host system you can now tell pulseaudio to redirect the sound to the sink "Stora". You should then hear the sound comming from the Stora.
