[arm-allstar] Sound devices supported by V 1.5

[Michael Hebert]

David,

Thanks for the info. I have several devices that use multicast to tx/rx
audio across networks. Two examples are the Telex IP-223 and Cisco 2610xm
router with E/M cards. It is just something I have thought would be useful.
If the audio is already there in the multicast stream, it would be nice to
bring it directly into the channel driver thru rpt.conf.
