GSM Shield V2 -> No input on audio jack

The GSM Shield 2 uses the wrong audio channel for the M10 chipset, so I've managed to the library by adding a AT+QAUDCH=1 command to the startup procedure. Now I get audio out through my headphones, but the input doesn't work. I've tried AT+QMIC to set microphone gain levels to maximum on all channels, but it still doesn't work. Can anybody help?

Thanks for the "AT+QAUDCH" command. Now I also get sound in the headphones.
Have you tried using the mic connectors on the shield to see if those work?

Hello,

Could someone of you let run the Audio(Microphone or Speaker), and how ?

Thanks
