All I get is a beep. The LED is working fine. That amazon seller, importer520 was so slow to ship it took 6 weeks to arrive. Would have been cheaper to get a cm119 chipset off ebay. I ordered a few of them, for $2-5. Now I wait again. Anyone have a driver for the amazon card? * paste from kevin above http://goo.gl/A6Bxb (model PD552) * I bought the USB soundcard from amazon that the lifehacker article, and kevin (above) linked to.

I tried to see if there was a driver issue but couldn't really figure it out. Are you using a WL-520GU? My sound card is http://goo.gl/A6Bxb (model PD552). I can't seem to put my fingers on why this is happening. I am having the exact same issue, Jesse. I tried to see if there was a driver issue but couldn’t really figure it out.

The comments section of these posts is not a good place for me to give troubleshooting advice (it gets quickly lost). I have heard of issues with a continuous beep before, in fact you are not the only person to run into this problem: http://mightyohm.com/forum/viewtopic.php?f=2&t=171&p=849 I believe the workaround is to load kmod-alsa and enable the ALSA drivers in mpd.conf. There can also be sample rate problems. What is dmesg reporting the about your usb-audio device’s capabilities? I think 44kHz is good, 48kHz can cause problems. Pawel,

I have WRT54G-TM running OpenWRT now. All reconfigurations made as You ordered in part 3-5 of this storry. USB sound device is detected. Network reconfigured... But... When command mpc play is sent, I can hear only continuous "beeeeep" on the headphones. When "status" is requested to mpc - I can see it is connected to proper stream and is able to display the stream name. This name changes folowing what is sent by the radio station at the moment. I can also change volume of my "beeeep" ;) So it looks like almost everything is working. What I suppose as potential source of problem is, that USB2.0 spec requires 15k pull down resistors whilest i left original SMD elements which are 47k. I'll try to change these elements and maybe I will win this little war :) Maybe You can tell me other hints? Maybe driver is not proper one? Did everybody meet the same situation? When this issue will be solved - I think about ATmega8 interface for IR remote (commands via ATmega's UART) and also for 2x16 LCD display ("mpc status" to router and then router's replay parsind and displaying proprt parts). At this time - my respect for Your work for Asus. Folowing this, step by step, a newby like I was able to deal with OpenWRT on WRT54G-TM and almost do the same conversion :) Regards Hello Jeff

My fault. The router I plan to use is WRT54G-TM. First one is working fine under DD-WRT as a "master router" at my flat, second will be turned into radio in case of success ;). This second router is already HW modified by being equiped with USB and SD card reader. Both modifications are working fine so there is a time to force this device to make some sound. The additional target is to force ATmega8 to reac RC5 IR remote commands and drive this radio remotelly. But I'm constrained with commands to be sent via UART to router - I need to learn them and to implement them (I'm using Bascom to create programs for AVR uCPUs) Anyway - I saw somewhere in the network, that there is possibility to add one USB 1.1 port to WRT54GS too.

I was not aware that it did (even on the PCB). It is possible to use a hub with the WL520gU and multiple USB devices. There are some problems with large flash drives on the older kernel versions (like the one I used in my project) but I believe there are workarounds (different filesystems, kernel modules). Some of the members of the forums here have used a USB drive to add capacity to the WL-520gU, which barely has enough space as it is. I think you will find using the limited space of the WRT54GS challenging, but that doesn't mean you should give up on it. :-) Does the WRT54GS have USB onboard?

So the story is: I have old WRT54GS found somewhere at home. I know this device has only 2Megs of flash. Question is: is it possible to mount 2 usb ports (it is pssible) and put USB audio card into one of them and old 2 Gig flash into second one - to split OpenWRT based radio software both onto internal flash and mounted usb dongle? Did You tried to think about such challenge? :) I found that router's 2Gig flash can not handle whole firmware, so I'm looking for some bypass instead of throwing this oldschool router into rubish bin :) Regards Hello Jeff
