Hello, I have the following problem. When I change the speaker volume using the following code, everything works: stream = pjmedia_snd_port_get_snd_stream(sndPort); status = pjmedia_aud_stream_set_cap(stream, PJMEDIA_AUD_DEV_CAP_OUTPUT_VOLUME_SETTING, &volumeSpeaker); But if I use PJMEDIA_AUD_DEV_CAP_INPUT_VOLUME_SETTING instead of the PJMEDIA_AUD_DEV_CAP_OUTPUT_VOLUME_SETTING for microphone volume control, function pjmedia_aud_stream_set_cap returns error PJMEDIA_EAUD_INVCAP (420008 - The audio capability is invalid or not supported). Is there some way to control the volume of the microphone or the microphone dis/connect from the port?
