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. -- Jim M0HPJ.
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

George, Thanks for the reply. 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?

Is the radio transmitting or is it just transmitting with no audio?
I've not yet modified the fob to take PTT out, and it's not connected to a radio yet - just some headphones (which work) - I wanted to prove the fob worked before progressing further.
Have to tried using the other channel?
They're stereo headphones - nothing out of either side. Jim M0HPJ On 6 January 2012 14:41, Corey Dean <n3fe@repeater.net> wrote:

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.

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. Jim M0HPJ. On 6 January 2012 17:42, Corey Dean <n3fe@repeater.net> wrote:

So the plot thickens ... 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, Jim M0HPJ.

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...:)) -- Bryan In this world, you must be oh so smart or oh so pleasant. Well, for years I was smart. I recommend pleasant. You may quote me. Sent from my MacBook Pro.
I don't think this is your problem since the green led is flashing but make sure you've updated to the latest SVN On 1/6/2012 3:34, Jim Whiteside wrote:

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.
