I'm working hard to get a basic AllStar system running, and struggling
to find a suitable USB Fob to modify (trying to do it on a budget)
I've been unable to get hold of the exact model shown in www.qsl.net/kb9mwr/projects/voip/usbfob-119.pdf, but now have several
of a very similar one with the printed description 'Virtual 7.1Ch
Sound' and a slightly translucent case.
lsusb reports the device as 'ID 0d8c:000c C-Media Electronics, Inc.
Audio Adapter.' which I think might be CM119 or similar.
When plugged in the green led starts to flash, but I've not yet been
able to get any audio out of it - even when running 'rpt fun <node>
*80' from the Asterisk CLI
I wanted to confirm this was a suitable fob before going to the grief
of modifying - it's much more SMT than in the above PDF, and you can't
actually access the pins on the chip itself as it's under a 'bubble'
of a ceramic compound.
also try (from asterisk command line) "radio tune"
From my 2360 node:
...
Tx Voice Level currently set to 350
Tx Tone Level currently set to 160...
If those are too low you might not get anything out.
ALSO...to transmit tone "radio tune txvoice" should put out a tone.
*80 (default setup) makes the thing ID, and if that isn't setup correctly might give you no audio.
Another point is that I no longer modify USB Fobs. The ones I use are identical to the ones in that pdf. But I use the PC's parallel port lines for COS in and PTT out, much neater.
I also do DC blocking (the caps) in the radio.

txmixa was set to 'composite', txmixb to '0' - changing this also to
composite didn't make a difference. Do you know what
asterisk*CLI> radio tune txvoice
Current txvoice setting on Channel A is 500
Tone output starting on channel usb28233...
Tone output ending on channel usb28233...
asterisk*CLI> radio tune txtone
Current Tx CTCSS modulation setting = 200
Neither of the above did anything.
If I copnnect to the node using IaxRpt, *80 ID's fine from that
application, but not from the fob. Also I can connect to another node
and have a QSO using IaxRpt, but again nothing from the fob.
I'm plugging stereo headphones into the fob headphone jack.
Interesting advice about using LPT for the GPIO - I might pick your
brains about that if I can get the audio working - I'd rather avoid
the expense of buying in URI - the shipping is almost as much as the
device to the UK, and I'd like the challenge of working it out.

Is the radio transmitting or is it just transmitting with no audio? Have to tried using the other channel? If you are using the left side have you tried the right side?

They're stereo headphones - nothing out of either side.

I don't think you are going to hear anything unless they are powered. Try a set of powered computer speakers on the headphone jack and I bet you will hear something.

Take the FOB and plug in to a windows PC. Confirm that it works there using
windows media player or something. If not then you have a bad USB FOB.

I now have three of the same type of fob - bought from different

from Asterisk, into the same headphones that produced audio from
iTunes.

I think you may be SOL in trying to use them, then. There are devices which are known to work (whether they're DMK's URI or other CMedia-based devices is immaterial); these obviously don't based on your description(s).
Question to ask yourself (which I do all the time, whether it's ham radio Stuph or building Lotus Europas or....???) is whether your time or cash outlay is worth more.
(full disclosure, I hate hitting my head against brick walls...sometimes, it's just cheaper to expend currency than to expend time to get something to work that never will...:))

Well, for years I was smart. I recommend pleasant.
You may quote me.
Many thanks for that info Corey - I've just found someone in the UK
selling that model (eBuyer.com) at £10.85.
I'll let you know how I get on.

A 'StarTech.com USB to Stereo Audio External Sound Card' turned up,
looking identical to the one identified by Corey.
Documentation says the chipset is 'C-Media CM108AH', and indeed when I
break the case open there's a nice SMT CM108AH with exposed leads that
I can hack if I go that route.
lsusb reports it as 'ID 0d8c:013c C-Media Electronics, Inc.'
But ... still no audio!!!!!
In desperation, I resinstall everything from the ACID disk I got from
allstarlink.org, and lo-and-behold it works! And, all of the other
fobs work too.
Anyone want a USB Soundcard?
Still no idea why it didn't work first time round, but there we go.
Many thanks for all your help,

I know this is an old post but I have an old ACID system and need some help. I have been using a URI on my Allstar system for many years and it has worked fine (an older ACID installation). I recently had a failure of the motherboard on the computer I was using so I had to move the hard drive to another computer (from an old Atom D525 CPU motherboard system), to an old Dell Optiplex 390. The Allstar system came up fine and everything appears to be working ok, the green LED on the URI is blinking and the system creates the audio output for IDs and the like when listened to on a VoIP phone connected to the system over the LAN network. However there is no audio when heard from another radio. The system keys up the radio connected to it but there is no audio. The system receives over RF OK, I key up another radio and I hear my voice on the VoIP hone connected to the system. One thing I do notice is that the rate the LED on the URI blinks is about half as fast as it did when connected to the other computer. I’ve made several adjustments to the USBRADIO parameter of TXVOICE, moving it up as far as 300 (it was originally at 25 on my old system) and still nothing on the output of the radio (a Kenwood TM-G707 is connected to the URI and my system). There is also no tone heard on another radio when performing the RADIO TUNE TXVOICE command from within Asterisk. Other than a potentially defective URI, can you provide any insight on where I should look next to troubleshoot? I know I should upgrade to a newer Allstar system but I was hoping to get just a bit more life out of the current setup. Any help appreciated.
