remote trouble

[and.kuznetsov]

Hello colleagues!  Possibly after Firmware reset of С40 the microphone from the kit stopped working. We've tried another mic, cable, port - nothing is working. Another problem is that I have only remote access to the C40. Could you please tell me if C40 has some xcommands to troubleshoot this issue. Software version is very old CNC6.0.0.876266.

You could use the command:

xconf // mic

to get the output of the configuration for the microphones.   There you should be able to see if they are turned on and what their configuration is.

I'm not sure if it's present back on that old TCNC6.0 software or not, but it's in some of the newer software releases (I'd suggest you upgrade if you can) - you can try

xstatus // mic

which will show you whether the mic is seeing any activity:

*s Experimental Audio Input Connectors Microphone 1 Activity: True
*s Experimental Audio Input Connectors Microphone 2 Activity: False
*s Experimental Audio Input Connectors Microphone 3 Activity: False
*s Experimental Audio Input Connectors Microphone 4 Activity: False

And, viewing the web interface of the codec, go to Configuration > Peripherals, and you can see the microphone status there too, as well as being able to click a "Start VU Meter" button to view the activity on the mic.

Thank you for your suggestion.  I'm not sure but the mic configuration seems to be fine

xconf // mic
*c xConfiguration Audio Microphones Mute Enabled: True
*c xConfiguration Audio Input Microphone 1 Type: Microphone
*c xConfiguration Audio Input Microphone 1 Mode: On
*c xConfiguration Audio Input Microphone 1 Level: 14

*c xConfiguration Experimental Audio Input Microphone 1 Channel: Mono
*c xConfiguration Experimental Audio Input Microphone 2 EchoControl NoiseReductionMode: Normal
*c xConfiguration Experimental Audio Input Microphone 2 Channel: Mono
** end

In the WEB interface -> Peripherals there is no any information about the microphones as well as  VU meter. 

That is the output when i'm making a conference with myself

xstatus // mic
*s Audio Microphones Mute: Off
*s Conference Site 12 MicrophonesMuted: False
*s Experimental Audio Input Connectors Microphone 1 Activity: False
*s Experimental Audio Input Connectors Microphone 2 Activity: False
** end

That's a bit strange because a couple months ago everything worked fine and nobody changed the connections for the mics.

It could be that it's just the mic has failed after all those years of use (or the cabling somewhere between the mic and the codec has failed).   Try using another mic connected directly to the C40 to see if it's still an issue then or not.  It's very unlikely from what you've sent to be a setting on the C40 that has stopped it from working, if it is all connected directly.  The only other possibility is that there is some external audio processor that is performing the mic function and passing the audio in to the codec - this may need to be investigated on site though, and probably not something you can easily determine remotely.
