Hi Guys,
I am using the SYBA fob on my node. It was easy to do the mod on.  I tried 
the other one and the pads are so easy to peal off.

Steve,

Folks have used the CM108/109 and CM119 and the SSS1623, which is a
compatible chip.

You can get a datasheet for the CM119 here:

http://www.repeater-builder.com/voip/pdf/cm119-datasheet.pdf

Here is one that you can use on Amazon for $6.20

His is another fob for $3.87 with free shipping.

In the future the CM119B will probably be supported, just an educated guess.

Hi I've not been on in about 7.5 years.
Back then Jim Dixon was a regular contact and somebody I chatted with fairly 
often.
So sad he is gone!

Way back then the only supported simple sound interface was USB and required 
a CM108 or 109
chip and the idea of using anything else soundcardwise
was just immediately shot down if asked.
There were reasons (back then) for this and I think it was centered around 
the author not
wanting to have to deal with the issues and support of it.

I never cared about support or "all of the issues" it may cause on my end 
but lacked the
technical know-how to write a "generic" audio driver myself.
A LOT of linux software is NOT soundcard driver specific and works well with 
just about ANY
sound interface that is on a motherboard or card or whatever.

And I never needed the GPIO to be on the sound chip.
Nor did I need all of the DSP functionality to be done in the CPU via the 
sound interface.
I'm curious if there have been any developments since that allow more sound 
interfaces to work
or is it still the same and require a CM108/109 type USB device?


Thanks!!
