TomatoUSB

Hello!

I'm kinda new to this whole "Tomato world", so forgive me if this is a stupid question.

I want to by ASUS WL-500GPv2 router, instal tomato, connect an USB sound card and stream music through AirPlay. Sound card that i'm using is Audiotrak Prodigy Cube USB sound card (audiomagic. eu/headphone-amplifiers/20350-audiotrak-prodigy-cube.html).

My question is: will it work? Is this router good for such application, or should I look for something else? I DON'T want to use cheap 1$ sound cards - I want to use this particular sound card. I don't need any other features, only AirPlay (and maybe AirPrint).

My question is: will it work?

The router won't be an issue since it'll run TomatoUSB.

The Audiotrak Prodigy Cube USB sound card is unknown. Google is your friend (looks like it is supported under linux, so chances are good). Do you already own it? If so you're the best person to answer the question (you'll have to test it and report back).

Currently you can't use AirPlay and AirPrint on the same router.

Thank you for your answer!

Finally I got my router (it's Belkin PlayMax N600HD), and I can confirm that Audiotrak Prodigy Cubie IS WORKING under Tomato.
On the other side, I can't properly install shairport - opkg install shairport gives me * wfopen: /usr/sbin/shairport: Read-only file system" error. Other stuff installed without any problems. Any ideas what may cause this?

Thanks. Someone reported that shairport issue to me yesterday (was it you?). I'll try to take a look at it today.

[Edit - I went ahead and updated the tutorial to point to a know good working version of shairport for now. Can you give it a try and report back? Thanks

Now everythnig working perfect.
(Got md5 missmatch error with opkg install libao_1.1.0-1_entware.ipk, but installing libao from gl500g-repo solved the problem.)
Thanks a lot again!

Good to hear you're right on top of this. I was following your tutorial last night with my N300 and was getting the same errors, figured I was doing something wrong. I'll try this tonight when I get home from work. Thanks!

@doug, I do ask people to leave a comment if they have issues. :)

If you go through the tutorial tonight, can you please let me know if you run into the md5 mismatch error mentioned above with libao. Also, let me know if you're interested in testing a newer version of shairport. It's suppose to be better somehow, but I haven't had a chance to test it thoroughly, except to confirm it works. I also need some help verifying the volume (a user complained it was too loud). I have instructions for lowering the volume but haven't published them yet. Thanks

Yes… I also get the md5 mismatch, so I did the same and used the libao from wl500g-repodotgooglecodedotcom/svn/ipkg/openwrt/ and that worked fine.

I'm all for testing a new version of shairport, this is all new to me anyway. The initial volume with madplay about blew my ears off. The default volume for shairport seems to be more tolerable, but I'm currently just playing it via some earbuds.

Thanks

@doug, thanks for confirming the md5 issue. I've updated the tutorial so that libao install directly from the repo.

Regarding:

I also used the "tomato-F7D3302-1.28.7501.3MIPSR2Toastman-RT-Mini.bin" for the initial flash because the DD-WRT file you posted above wasn't working on my router.

Can you provide me a link to download that particular file? Since you tested it, I wanted to use the exact version you're using.

Here is the link to the newer version of shairport - http://dl.dropbox.com/u/42238/entware/shairport_0.05-20130121-1_entware.ipk

You need to specify ao_driver on this version for some reason.

shairport -a "Living Room" -b 282 --ao_driver=oss

For volume adjustment try the following

#install alsa-utils
opkg install alsa-utils

#link the correct sound device
mkdir /dev/snd
ln -s /dev/controlC0 /dev/snd/controlC0

#required for amixer
echo "audio:x:3:" >> /tmp/etc/group

#Check the mixer name. PCM in my case
amixer

#Simple mixer control 'PCM',0
#  Capabilities: pvolume pswitch pswitch-joined penum
#  Playback channels: Front Left - Front Right
#  Limits: Playback 0 - 128
#  Mono:
#  Front Left: Playback 128 [100%] [0.00dB] [on]
#  Front Right: Playback 128 [100%] [0.00dB] [on]

amixer set PCM 70% 
#Simple mixer control 'PCM',0
#  Capabilities: pvolume pswitch pswitch-joined penum
#  Playback channels: Front Left - Front Right
#  Limits: Playback 0 - 128
#  Mono:
#  Front Left: Playback 90 [70%] [-38.00dB] [on]
#  Front Right: Playback 90 [70%] [-38.00dB] [on]

#required for amixer
#To make the volume stick
#Add the two commands to the run after mounting section
echo "audio:x:3:" >> /tmp/etc/group

amixer set PCM 70%

works….you've just got to drop it quite a bit before you notice it.

5 - 10% is decent for unamped head phones, 70% is still quite loud.
