My thoughts were to hook up a USB soundcard to the omega and run an OpenWRT flavour of opensource squeezbox software. There is one from 2012 called squeezslave, it's only ~200kb and as long as it runs could be what I need.

https://code.google.com/p/squeezeslave/downloads/list?q=label:OpSys-OpenWRT

I thought I'd create this post to see if anyone is interested in something similar.

opkg install http://squeezeslave.googlecode.com/files/squeezeslave-oss_1.2-r365AA_ar71xx.ipk

If you run opkg list it comes up as squeezeslave-oss so you can easily remove it.

However I cant get it to run as it doesnt recognize my USB audio card, so thats next on the list.

[ 1572.280000] usb 1-1: new full-speed USB device number 3 using ehci-platform
[ 1572.470000] input: C-Media Electronics Inc.       USB PnP Sound Device as /devices/platform/ehci-platform/usb1/1-1/1-1:1.3/0003:0D8C:013C.0002/input/input1
[ 1572.480000] hid-generic 0003:0D8C:013C.0002: input,hidraw0: USB HID v1.00 Device [C-Media Electronics Inc.       USB PnP Sound Device] on usb-ehci-platform-1/input3

this to me looks like its recognised the MIC (ie input) but not the output part of the card?

Setup the cross-compile env and looked like I added the required kernal modules, compiled it, once I've loaded it, it fails to boot. LED comes on for a short time then off again.

Need to have a look at the serial console although windows doesnt recognise the USB device

I'm very interested in doing quite the same thing.
Did you have any success with running squeezeslave on the omega?

Thanks

opkg list | grep audio | grep usb

Of course,
opkg list | grep usb
leaves a lot of experimenting yet to be done! Sadly, "opkg install sox" on most of these (sox here used as example) gives:

• satisfy_dependencies_for: Cannot satisfy the following dependencies for sox:
• kernel (= 3.18.20-1-7bed08fa9c06eb8089e82c200340ec66) *
• opkg_install_cmd: Cannot install package sox.

On the other hand, usbreset does seem to work so there is a connection to the 3D dongle.

• opkg --force-depends install <package-name>

The worst that can happen is that the installed package really doesn't work with the older kernel, in which case you can remove it using:

• opkg remove <package-name>>

And other than not having the package you want, you are no worse off.

FYI: I have done this with a few packages that initially indicate problem with kernel version dependency and have had no problems.

I'm hoping we get all the kmod-* packages over soon, as that will dramatically increase the amount of hardware we can play with!

However, in my opinion you are highly unlikely to cause any damage by using a package with mismatching kernel version - and some times it is the only way to progress while waiting on getting the right version.

But bottom line is that it is up to the call of each individual to decide whether it is worth it or not and to have a recovery plan if it doesn't work (usually just a removal of offending package, sometimes a factory reset) - but a lot of this is all part of the experimentation/development process.

Here you can find my compiled kmod-sound-core_3.18.23-1_ar71xx.ipk and kmod-usb-audio_3.18.23-1_ar71xx.ipk.

Please check before, that there are no other versions installed with these commands:
opkg remove kmod-usb-audio
opkg remove kmod-sound-core

After that, install both packages with:
opkg --force-depends install kmod-sound-core
opkg --force-depends install kmod-usb-audio

Have fun and enjoy

Great little device

which files do you need? For getting usb audio to work, or squeezelite, or squeezeslave?

But in general you should be able to find it here: https://www.dropbox.com/sh/g12gf4ko9512pec/AACDj55QPvxf46LM1V5AwpHoa?dl=0

For usb audio devices @fader also wrote a great howto.
