The flashing green light is a good sign. 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. ----- Original Message ----- From: "Jim Whiteside" <jaydublu2002@gmail.com> To: <app_rpt-users@ohnosec.org> Sent: Friday, January 06, 2012 5:34 AM 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.
