The symptoms you explain sound like either a bad power supply or a bad AC adapter.
What options do you have on your IRLP Embedded Node? Is it in a standard case or a rack mount? Does it use the variable voltage power supply (DC Option)?
Was there any "event" prior to the audio reduction issue that may point to the source of why the radio audio was low? Lightning, power outage, etc.
Someone mentioned the BIOS corruption, and there may be a few tests we can do to try to revive it or determine what is wrong.
A power supply replacement would be about $60, a motherboard replacement would be about $200. There is nothing that can really go wrong with the other parts. :)

This EMBEDDED IRLP system has been in use for more than a year with good services. While on the bench the 120 vac power cycled rapidly and the computer would not reboot after this. When repowering the computer the transmitter is pulled up into transmit and stays high.
