WTware RDP client

Hello,
I am using a WTware 5.6.24 and I am with a problem with my Microphone Jack. My microphone is not recognized.
I am using the following parameter:
sound=on, amixer:cset numid=3 1
microphone=hw:1:0
Parameter as "microphone=on or microphone=hw:2:0" is not recognize.
I need your help, please.

What is your Microphone Jack? There is no microphone input in Raspberry Pi sound jack. Not implemented in hardware. You should use USB microphone or USB headset for Raspberry Pi.

I can hear audio normally with these headphones, but I can't use the microphone. I'd like to know if there's any way to use this microphone. I don't have USB headphones.

You can not connect microphone to Raspberry 3.5mm jack. There is no hardware for microphone input in Raspberry. You should use USB microphone or USB headset.
