Hi Iain !
Try looking at the SBCs from Advantech. http://www.advantech.com
They have several that include sound as well as ethernet, LCD and the rest of
the standard interfaces. I have never tried PD on one, but did try the sound
under Windows once. Advantech also has things like Flashdisks so you can use
a standard operating system, but still no moving parts. Just don't expect
the flash file system to be too fast. I have used several SBCs from
Advantech for measurement systems and also as communications and file servers
and they have all run reliably using both Windows and Linux.
If you really need sealed enclosures your biggest problem will probably be
getting the heat out. Even the so called low-power processor on the board I
have gets quite hot. I have seen custom made housings with deep ribbing on
both the inside and the outside for this type of application, but you then
need a ventilator _in_ the housing to spread the heat evenly over the entire
surface. Check the life expectancy of the ventilator at higher temperatures,
50° or 60°C. The life expectancy is normally only given at room temp. Inside
the housing it will be very warm and when the bearing grease starts to flow
you can imagine what happens.
Good luck with your project, I hope I could help you some.
