SBC newbie, architecture questions (for PulseAudio application)

Hey everyone,

I've searched high and low, but can't seem to find the information I'm seeking...

In the realm of single board computers, I'm finding that there are a number of different RISC, ARM, and x86-compatible variations available that all seem to be suitable for my needs (low-power, embedded ethernet, and audio out). Unfortunately, I'm not sure what will best suit my needs in this case.

This SBC will be used to run a barebones Linux kernel and distribution, needing only ALSA, PulseAudio, and basic network services (DHCP client). These will serve as dumb audio output heads, receiving audio from a Pulse server.

Now, I'm not too sure about Pulse's efficiency when only receiving a network audio stream (no encoding/decoding). Would something in the realm of a 200 MHz StrongARM be sufficient, or do I need to look higher on the scale?

Thanks in advance... If any clarification or additional details are needed, please let me know.

A french company is doing an internet radio based on ATMEL SAM9 processor @ 190Mhz.
So such processor should be enough for your system.
