Squeezelite sound output stops after a few hours on Armv5 Pogoplug with Arch

[GoogleCodeExporter]

What steps will reproduce the problem?
1.  Configure squeezelite to start as a service and start it with systemctl.  
This is the command from the service file:

/home/peter/squeezelite -m ab:cd:ef:12:34:59 -n dining

2.  Listen to pandora without issues for hours.  Go to bed.

3.  Wake up 8 hours later with this player "dining" still showing up in LMS, 
and with the service still showing up in "htop", but with no output at the 
speakers.

What is the expected output? What do you see instead?

The expected output is high quality sound which works for hours after starting 
the service.  
This problem is totally resolved by either rebooting, or stopping and 
restarting the systemctl service.

What version of the product are you using? On what operating system?

The version is squeezelite-armv5te, and this is running on Arch Linux on a 
Pogoplug V4 which has 3 USB ports- one is occupied by an Edimax wifi dongle, 
and one is occupied by a C-Media audio card. 

Please provide any additional information below.

I have replicated my setup on two separate devices at the exact same time, and 
they both produce the same issue.  After the initial setup of Arch, and getting 
wifi working, these are the instructions that I followed:


pacman -Sy faad2 libmad mpg123 libao alsa-utils avahi

#audio fix
echo "use_mmap=no" >> /etc/libao.conf

#Configure alsa - asound.conf file
cd /etc
wget https://dl.dropbox.com/u/42238/pogoplug/v2/asound.conf


cd /home/peter

#download the latest squeezelite version
wget http://squeezelite-downloads.googlecode.com/git/squeezelite-armv5te
mv squeezelite-armv5te squeezelite

#make executable
chmod a+x squeezelite

#download service file
cd /etc/systemd/system
wget http://dl.dropbox.com/u/42238/pogoplug/v2/squeezelite.service

#edit the service file accordingly
