Hi, Since the day Dan authored this question, he, myself and Michael Keuter dug into it.
The solution can be found here, now part of or documentation: External Music on Hold Source http://doc.astlinux.org/userdoc:tt_external_moh_source While some AstLinux hardware may provide an onboard analog line-in jack, Dan found his resulted in quite a bit of background noise, not to mention added lib/util bloat to our image to simply be able to unmute the input. It became clear that a USB Sound Adapter was the best choice, works for any AstLinux board, doesn't require ALSA libs and utils, and little to no background noise. There are a multitude of USB Sound Adapters available, probably best to stay away from the $5 dongles, I like versions with some sort of USB pigtail to not cover other ports and get the analog portion further away from the main board. If anyone has success with a different USB Sound Adapter than listed in the above docs, please reply here with it's lsusb info and product description so we can add it to the list.
