squeezelite stutters on RaspberryPI

```
What steps will reproduce the problem?
1. Install RaspberryPI using Raspbian image
2. Start squeezelite using /usr/local/bin/squeezelite-armv6hf -o default -n
Kantoor -d all=debug -f /var/log/squeezelite.log -z 192.168.110.188
3. Start playing music

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

Normal sound output is expected but in stead it is playing garbage (seems like
audio is delayed) I`m also running sqeeuzelite on windows and ubuntu is they
are playing fine

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

/usr/local/bin/squeezelite-armv6hf --help
Squeezelite v1.1, Copyright 2012, 2013 Adrian Smith.

root@pi:/var/log/apt# cat /etc/issue
Debian GNU/Linux 7 \n \l

Please provide any additional information below.

Today during testing the sound seems to be okay after some time playing bad
sound. But after restarting squeezelite i cannot reproduce this and the sounds
seems to keep bad

I was using squeezelite for some weeks on the RaspberryPI without to much
problem. Maybe it is because i rebooted the unit last night, or because of
installing updates. I`m not sure what caused it.

I can play mp3 files without any issues using mpg321 (both localy and using NFS)
