Since I put up the information to add chan_alsaradio to be used as a local speaker for the RPI2 I have been asked if there is a simpler way to achieve a local monitor speaker. After thinking about it for a while I came up with the following: Do we really need to add alsa just for a speaker? Do we need to add a channel driver from a outside source? What else can we do? We are already using oss for audio on Asterisk. Asterisk has a stock channel driver called chan_oss. It can be used as a simple way to listen to the node on a external speaker. This does not require much other then a way to adjust the speaker level. I've posted the basics on git. <https://github.com/N4IRS/AllStar/tree/master/platforms/rpi/rpi2/monitor> Thanks to everyone that is feeding back comments. The best way I know of to improve things. 73, Steve N4IRS
