TomatoUSB

Internet Radio (USB Audio) on Belkin ShareMax N300 (F7D7301) running TomatoUSB.

This project was inspired by the internet radio project based on the ASUS WL-520GU on Mightyohm.com.

I will continue to edit/update to flush this out, but wanted to capture the details while I have it fresh in my mind.

Hardware Specifications for F7D7301 v1 (similar to Asus RT-16N):

Broadcom BCM4716 Rev1
453 MHz CPU
8 MB Flash
64 MB RAM
2x USB 2.0
WPS Button (to be used to switch channels)

What you need:
USB Audio adapter - I'm using is the cheapy "3D Sound" ones you find on ebay for under $2 shipped. However, it should work with other usb audio adapters and usb speakers.
USB Hard Drive or Flash Drive.

Firmware I running: Shibby's Big-VPN - specifically "tomato-K26USB-1.28.RT-MIPSR2-101-Big-VPN.trx"
Get it here: http://tomato.groov.pl/download/K26/build5x-101-EN/

-Enable USB 2.0 and 1.1 support within the GUI under USB and NAS
Not sure if UHCI is needed, but OHCI is for sure.

-Plug in your USB HD/Flash drive and USB Audio Adapter.
-Setup Optware
I recommend this tutorial - http://uk.nyclee.net/2012/04/28/installing-optware-in-tomato-usb-shibby/
-Download the optional kernel modules "extras-mips2.tar.gz" from the same folder as you got the firmware.

cd /tmp
wget http://tomato.groov.pl/download/K26/build5x-101-EN/extras-mips2.tar.gz
mkdir /opt/extras
cd /opt/extras
tar xvzf /tmp/extras-mips2.tar.gz

load the extra modules

insmod/opt/extras/soundcore
insmod /opt/extras/snd
insmod /opt/extras/snd-hwdep
insmod /opt/extras/snd-page-alloc
insmod /opt/extras/snd-timer
insmod /opt/extras/snd-pcm
insmod /opt/extras/snd-seq-device
insmod /opt/extras/snd-seq
insmod /opt/extras/snd-rawmidi
insmod /opt/extras/snd-seq-midi-event
insmod /opt/extras/snd-seq-midi
insmod /opt/extras/snd-mixer-oss
insmod /opt/extras/snd-pcm-oss
insmod /opt/extras/snd-usb-lib
insmod /opt/extras/snd-usb-audio
#insmod /opt/extras/input-core
#insmod /opt/extras/hid
#insmod /opt/extras/usbhid

To autoload the extra modules during boot up, add all the "insmod /opt/extra/xxx" commands in the 'Run after mounting" box under USB Support in the GUI.

Run dmesg and check if usb audio card got detected. You should see something like this.
[code]
input: Generic USB Audio Device as /class/input/input1
input: USB HID v1.00 Device [Generic USB Audio Device ] on usb-0000:00:04.0-1
[/code]

Do a quick test to confirm usb audio is working correctly.

ipkg install madplay
wget -O - http://ca.ah.fm:9000 | madplay -

Did you hear some music? I hope so.

Install MPD from Shibby's repo - http://tomato.groov.pl/repo/
[code]
ipkg install http://tomato.groov.pl/repo/mpd_0.16.2-2_mipsel.ipk
[/code]

Configure mpd.conf (use many of the pre-existing ones for now).

More to come.

Hmmmm, guess you didn't look at the TomatoUSB Documentation page.

http://tomatousb.org/doc:play-audio-with-usb-audio-adapter

Hey ray123! Yes I have looked at that page and various posting within this site and others. Big thanks to you, I believe I read most of your postings regarding this topic (not to say I understand it all).

However, the documentation isn't very clear and makes a lot of assumptions that the person setting it should know.

A couple of examples of things…
1 - no mention of having to enable USB 1.1 support for the Audio Card to be recognized
2 - the tarball didn't work with my firmware. The modules needs to be specific to the firmware you're running. Its obvious now, but while I was trying to get things setup, it cost me some time to figure out.
3 - the mpd configuration is also confusing (for people who aren't that experience with it).

I'm looking to providing a tutorial more specific to the particular router (Belkin N300) similar to the documentation provided by Mightyohms on the Asus WL-520gu.

Hi @grayman4hire,
can you please post a detailed post.I successfully configured MPD but everytime i have to load the kernel modules.Is there any way around?????

whenever i edit mpd.config to change music directory to /tmp/harddislk ….it never change
it only detect opt/music directory for music files…..
pls help ..how can i change the music directory in mpd.config
i have optware installed on a hdd and opt folder is only 1 gb …and i cannot put all my music files in 1 gb folder
so i have to direct it to other directory ….pls help

Sorry to leave this thread hanging…

I ended up on other projects - specifically the Arch Linux Arm on PogoPlug (E02) which BTW I got AirPrint and AirPlay working (with IOS6 support), which is one of the main things I was trying to get going with this project.

Will try to get back to this project and do the same.

@tom, I extracted the extra modules to /opt/extras. Then I loaded the modules by placing all the "insmod /opt/extras/xxx" commands in the 'Run after mounting" box under USB Support.

@itechie, sorry I'm not too familiar with mpd. My guess would be you're not editing the correct mpd.conf file.

Karma restored, so I updated my original post.

Very detailed audio tutorial. Currently on 102-mipsr1. Got 3 insert problem, hopefully Shibby will fixed it.

1. can't insert input-core.ko for MIPSR1, dmesg says

input_core: exports duplicate symbol input_unregister_handle (owned by kernel)

2. can't inser hid.ko for MIPSR1 dmsg says

hid: exports duplicate symbol hid_input_report (owned by kernel)

3. can't insert usbhid.ko for MIPSR1 dmsg says

usbhid: exports duplicate symbol hiddev_hid_event (owned by kernel)

My RT-N16 MIPSR2-102-Shibby can't and doesn't need to ismod the 3 modules:
inputcore.ko
hid.ko
usbhid.ko

It runs MPD nicely without them.
