Sorry to jump in with a question and long post but I need help.
I have been using Linux for quite a few years at home now, but can still get lost very easy, I have Opensuse 11.4 installed on a couple of machines and I am happy with the software, for much of what I do it works fine, Internet, docs etc. Perfectly fine.
Started to try and understand more by obtaining a couple of the Raspberry pi’s and have managed to get a NAS running from one of them, but things do take time with me, I can generally follow Blogs or guides, but!
I have what I thought would be a simple project idea, tried on the rasppi’s failed decided to try it with two PC’s running Linux (Suse).
The idea is to stream microphone audio from each computer to the speaker of the other, i.e. an intercom. Not after high bandwidth, mp3, video or anything complicated just basic speech, low level pcm, such as 16 bit 8 KHz rate type stuff (ALAW?). Delays can be coped with.
I have been searching around and found a package called rsound, done quite a few years ago, seems to have two main parts rsd and rsdplay.
I have installed this on both machines as there is a .rpm for the packages on SUSE but for the life of me can not get it to work.
Both machines use ALSA and kmix.
The package rsdplay says
rsdplay is a simple program designed to stream raw PCM audio, or valid RIFF wave files to an RSound server, using librsound. It primarily receives audio data from stdin.
I have two machines both initially have internal ip’s of 192.168.1.69 and 192.168.1.65, the first is known on the network as Linux-main-pc and the other as Linux-lass
Has anyone used rsound that can help stream the mic audio from one to another. I read the man pages but failed to get any audio from one to the other.
What is stdin in audio does it mean the microphone, line in how to check or how to change.
The end point for me is to try and set up a fixed intercom between my home and my mothers home, to provide her with a degree of permanent contact where if she falls etc. a crash or shout may be heard here.
I have tried Skype, but the computer gets turned off and left off, to much trouble to use it. So my plan would be when I can get it to work is have a rasppi at her house permanently on (2 Watts consumption) it is small discreet and with a small rf module can also provide her with a panic button.
Any and all help appreciated
