You need to solder and add several parts. Much easier to start from a Linksys NSLU2 and plug in a 802.11G stick and USB audio stick.

Does your WRT have USB ports? The usb-audio driver has been ported to OpenWRT, so you could use a USB audio interface attached directly to the WRT. I haven't tried this myself yet, but sooner or later I think I will. My "router" already holds my entire music collection on a USB harddisk (exported via NFS and samba), so this would seem to be the next logical step :) Dominic ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/mailman/listinfo.cgi/linux-audio-dev

Yes...thts exactly wat my question is, a wrt box which can play songs but since it doesn't have speakers i want to use cat5 as the transport media. Now my idea is to use the wrt as a decoder, an external DAC and the output of the DAC to the speakers, and the question here is about the feasibility of such an arrangement, will it work?

As far as I got it the task/question was to use the Cat5-cables for analog music-signals (which is not a problem) and have a digital (modified or unmodified) WRT-router route the music to different ports or to produce the audio-signals on its ethernet-ports (which is a problem, i.e. not possible).

[LAD] Re: Audio over Cat5
Regarding this whole audio over Cat5 thread, do we actually understand what the objective is of this exercise / project? Is the original authors use of terminology such that we know what is actually supposed to be achieved? When I first read this, I thought the idea was to produce some sort of network-transported audio stream, like that of a video stream, something which could be "listened to" by some network-connected client computer with its own audio output hardware. Since routers themselves have no speakers, I could not reach any other conclusion. Now it sounds more like a hack to get packets to somehow generate audio as a byproduct ... kind of like the audio version of streaming video via ASCII on a character terminal. Or a better analogy would be getting the old PC "speaker" to emit discernible sounds by sending digital data to it's IO port. It reminds me of a story my uncle the television engineer told me about how there was a scrap pile of old bolts and cables lying on the floor in the corner of the antenna-transmitter shack of the VHF TV station where he was chief engineer for a number of years before he retired. One day, after replacing a couple of guy wire mounting brackets on the tower (a tower of about 1200'), he threw the scrap hardware on the junk pile in the shack. Suddenly, he could hear the audio signal for the station coming out of the junk pile. He tried to leave the pile undisturbed after that to preserve the effect, but eventually someone bumped or otherwise changed the pile and it stopped "working". Sorry, I digress. So tell me again ... what is the real goal of this project? - Doug H ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/mailman/listinfo.cgi/linux-audio-dev
