I could only get rid of the choppy sound by lowering the USB speed, so if that’s a problem for you then these instructions won’t help…
I’m not claiming any of this is groundbreaking or even original. This is basically me pulling together all the information I found on various blogs and forum posts into one set of steps that seemed to be ‘current’. I hope I have given everyone the appropriate credit for their hard work, if not please let me know and I’ll fix it.
Install Raspbian (Wheezy) using NOOBS
Available from the Raspberry Pi downloads page.Get a USB soundcard
But check that it works with the Raspberry Pi. This is the one I used (because on of the reviewers had it working): Dynamode USB Sound Card 7.1Install gstreamer-1.0
Add the custom repository line
deb http://vontaene.de/raspbian-updates/ . main
to /etc/apt/sources.list as described in this forum post, where Defiant has compiled gstreamer-1.0 for Raspbian.Update the package information and install the upnp and gstreamer libraries.
sudo apt-get update
sudo apt-get install libupnp-dev \
libgstreamer1.0-dev \
gstreamer1.0-plugins-base gstreamer1.0-plugins-good \
gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly \
gstreamer1.0-alsa
Get and build gmrender-resurrect
From Henner Zeller’s instructions in the gmrender-resurrect repositorysudo apt-get install autoconf automake libtool git
git clone https://github.com/hzeller/gmrender-resurrect.git
cd gmrender-resurrect
./autogen.sh
./configure
make
sudo make install
Set up alsa and tweak the USB settings
I made the USB soundcard the default sound following the instructions in atom’s forum post:In /etc/modprobe.d/alsa-base.conf, comment out the line that prevents usb-audio from being loaded first, and add the line to prevent the on-board sound being loaded first:
Then configure the volume to be full using#options snd-usb-audio index=-2
options snd_bcm2835 index =-2
options snd-usb-audio nrpacks=1
sudo alsamixer
sudo alsactl store
I tried enabling fiq_split (whatever that is), but I still couldn’t get the playback to not stutter, until I lowered the usb speed to USB 1. Edit /boot/cmdline.txt to add
dwc_otg.fiq_split_enable=0 dwc_otg.speed=1
Install gmrender-resurrect
From inside the gmrender-resurrect folder
sudo make install
And then create a script to run at startup with some appropriate settings. Save this script as /etc/init.d/gmediarenderer (from Stephen C Phillips’ post on Making gmediarender start on boot - but with the command line changed for ALSA instead of pulseaudio). You’ll need a guid, which you can generate using your favourite guid generating tool (what? you don’t have a favourite guid generating tool – try http://www.random-guid.com/).

And then install the service with

And reboot.
