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?

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.

That's reporting in as a CM108 for sure.
From the source code: #define C108_VENDOR_ID 0x0d8c #define C108_PRODUCT_ID 0x000c
In usbradio.conf make sure that txmixa= and txmixb= something other than no
Example from one of my nodes:
txmixa=composite ;no,voice,tone,composite,auxvoice txmixb=composite
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.

Subject: [App_rpt-users] USB Soundcard Fob - no audio
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.
Any advice would be gratefully received.
