Just a note for supported hardware, I was able to get the USB SIIG Soundwave 7.1 card to work just fine. It cost me a whole $4 and has a built in preamp.

Has anyone tried using the adapter included with the Samsung – Pleomax Crystal 2.0 USB Speaker, PSP-7000W speakers found at walmart, amazon, etc? I’m curious if it would require a different driver or if the kmod-usb-core and kmod-sound-core would cover it. I’m also curious about how loud they might be…anyone know?

Cool, that’s great to know. I think there’s a good chance that those chips will work in 7.09 (what I am running on the Wifi Radio) as well. Thanks!

It (the wifi radio) also works with an USB sound card
based on chips from Texas Instruments.
You can find an overview here: http://focus.ti.com/paramsearch/docs/parametricsearch.tsp?family=analog&familyId=463&uiTemplateId=NODE_STRY_PGE_T
These chips are often used for somewhat better sound adaptors
with S/PDIF. And they are easier to get than the C-Media chips.
I’ve tested it with OpenWRT 8.09 on a NSLU2. Should also
work on an ASUS router.

Hello mightyOhm,
I found a datasheet from 2006 at “pdf.weeqoo.com/FileDown-1135086.html”. It’s quite a nice gadget.

I also bought one from deal extreme, but mine was blue. If it is the same thing, it only supports 48000 bitrate audio, not the 44100 bps stream that Jeff sets up in part 5.

in /etc/mpd.conf simply change
format “44100:16:2″
to
format “48000:16:2″

If this doesn’t work, try looking for supported audio modes in the boot sequence.

Your adapter is similar but not identical. I had no issues getting stereo output on the SYBA adapter on any of the three machines I tested it on. My guess is your problem lies with your adapter, your audio drivers, or your audio cable. Good luck!

CN – You’re right, these are very useful. I’m thinking about getting another one to add a cheap headset to my desktop computer for Skype. The best part is, the CM119 is supported by Windows XP, OS X, and Linux, so pretty much any computer will work with these. I don’t even think you need to load a driver.

I’m glad you are enjoying reading about the the Wifi Radio project. It has been a lot of fun to create.

Thanks for stopping by!

Thank you for bringing this delightful little gadget into the spotlight!

This is the perfect little doodad for fixing audio on laptops and little slimline PCs with busted audio. I do feel a little ashamed that I’m only thinking about the uses it’s being marketed for…

Good luck on your radio quest, and thank you for the tutorial. Beginners like me find it nice to see little “tricks” like your method for changing the serial pinout on the router.
