Comments on: Building a Wifi Radio – Part 5, Let’s Make Some Noise!

I haven’t noticed any quality issues beyond some digital noise creeping into the audio output. It isn’t severe but may be objectionable to an audiophile. If you have severe distortion, try another sound device. I know the SYBA works fine, but I have never tried any other USB to audio adapters.

Thanks for the hint, my soundcard also required the ALSA module. By the way, do you guys have quality issues? My soundstick produces a rather rasping sound when being plugged into the WL-520gU – it sounds good on the PC though. Any ideas why this could happen?

You are the greatest!
Everything worked after the first try.
Awesome tutorial.
I have a wlan radio, I cannot believe it.

Thank you so much !!!!

Radio Slay is also awesome, I like it.

Only thing, I got an error after starting mpd
unable to open db file “/root/.mpd/mpd.db”: No such file or directory
current locale is “C”

I am afraid I have to find out what that means.
But since it works I can live with this.

Thank you!

Ken,

I haven’t seen this one before. Are you using the firmware on this site as opposed to compiling your own or using an image from openwrt.org? Did you see any other errors in the rest of steps to this point?

I recommend re-posting this over on the forums where myself and others can better help you get things working.

I got the console port up with a MAX3232 chip and 5 .1uF caps.

This is where I am stuck at the moment:

When I type mpd, it says:

mpd: can’t load library ‘libstdc++.so.6′

Ok. Got it working:
Comment out “audio” in the file /etc/modules.d/60-usb-audio

Change repository in /etc/opkg.conf to

src/gz snapshots http://downloads.openwrt.org/snapshots/trunk/brcm-2.4/packages /

I also had to change dest to “dest root /jffs”

opkg update
opkg install kmod-alsa

Reboot. That’s it!!

Also have this annoying problem with a cheap USB sound card from China. Did you figure out how to install the kmod-alsa-modules? I can’t find them in mightyohms repository, is there somewhere else we can get them.

I’ve figured out how to disable audio, though, comment it out in /etc/modules.d/60-usb-audio. That stops the beep, but of course, there’s no sound at all….

Hi Peter.

I have the same problem, but I don’t know how to fix it.
Can you give a step by step in the Forum?

mpd 0.15 (curently in beta) is supposed to have support for MMS. There may be some work required to port it to the router. mpd 0.14 became very bloated and was pushing the flash capacity of the 520 due to a glib2 dependency. I listen primarily to Shoutcast so I have not run into this issue – what streams are using MMS?

hi,

I would like to know how to stream through mms protocol, using wma instead of mp3???? Many radio stations uses that obviously.

Danke

I have heard this before somewhere in the comments, I can’t find the post right now. I think the original poster was having issues with USB-audio on a high speed hub, as I believe you are. I have not been able to find that option in the 2.4 kernel, so I think it’s 2.6 only.

You may want to try asking about this in the mightyohm.com forums or over on openwrt.org.

This is probably a good excuse for someone to try and get the 2.6 kernel working on the WL-520gU. Wish it could be me, but I have too many other things going on now.

I`m working on WL500GPv2.
I can`t rmmod usbcore for some reason (unloaded all other usb-related modules).
The sound adaptor is chinese pd552. It works unless i load ehci-hcd.o. Then I have usb2.0 support, but no sound.
It seems that in kernel2.6 there is an option CONFIG_USB_EHCI_SPLIT_ISO, which should be enabled to allow usb1.1 sound cards to work on ehci hubs. I don`t know if this is available or `d help with kernel2.4/openwrt/mipsel.

@durin and @Nick, I would love to hear from you if you were able to get smb shares mounted. i wouldn’t mind turning this into a jukebox that can access a large library of mp3s, although i suspect i will have to install a usb drive for the mpd database.. could you post some tips? sounds like durin was able to get smb working – any ideas?

hi again jeff, i followed your tip and was able to get openwrt installed and mpd working great! thank you very much! i installed the firmware file you supplied, modified the network settings as directed, and am now able to ssh into the router without hacking a serial port in (yet).

what i would like to do next is allow mpd to access my music library stored on a smb share. do you have any tips on doing this? im running into ‘out-of-space’ problems when installing some of the smb-client options suggested on the openwrt site… or maybe i should see if i can get mpd using a mt-daapd library? hmmm..

Hi,
Do you have any ideas on how i can play files in mms (WinMedia) form, like for example : mms://kissfm.live24.gr/kiss2111?MSWMExt=.asf
Is it possible or mpd just plays m3u files? Thanks in advance
