Please forgive me if this is covered in a faq. I looked for one and didn't find it. I'm running an small stand-alone server app called "websdr" by Pieter-Tjerk de Boer in Holland, which accepts audio in quadrature on 2 channels (for instance the line-in port of the sound card). The audio comes from (what else?) a sdr .... external software defined radio hardware. It serves the results as a live web page on the internet. The client sees a waterfall display and hears the audio (typically from ham bands) that is nicely filtered per the users selections from the software defined radio connected to the server. The websdr author requires that the server have the oss compatibility package or that the server program be launched via aoss. I've got both and tried both but can't get the audio from the sdr into the computer. The server software is quite stable and is serving sdr audio to client web pages from half a dozen or so radios around the world. In fact I can't seem to get *any* audio into the computer! To try and simplify things, I tried playing the headphone output from a cd player into the line-in of the sound card using the small "sound recorder" app that comes with ubuntu and that doesn't record. The sound card plays back fine. I'm running Ubuntu Jaunty with all updates. My (main) sound card is Audigy4 (SB610). There is also a sound chipset on the mother board, but Ubuntu evidently doesn't know it exists. I have the following sound packages installed (I found these with synaptic using keywords "alsa" and "oss": libsd-alsa0 gnome-alsamixer alsa-utils alsa-oss alsa-base libasound2 libasound2-plugins oss-compat linux-sound-base pulseaudio-utils pulseaudio I'd appreciate any advice that can help me get the line-in and oss compatability working. I'd be pleased to run whatever diagnostics or other programs you recommend. I'll be happy to provide any info on the hardware or software environment I have, though I may need a bit of prompting on how to find them. Or if there are some well organized web resources you can suggest that might help I could try them too (I've been disappointed, though, so far with the audio diagnosis web pages that I've found on my own so far) .
