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?

 pjsua_conf_adjust_tx_level(0, volume);    

pjsua_conf_adjust_rx_level(0, volume);

I use: pjsua_conf_adjust_tx_level(0, volume); and pjsua_conf_adjust_rx_level(0, volume); to set speaker and microphone volume respectively, and works fine (0.0 <= volume <= 2.0). Notes: * I mute simply by setting mic volume to zero. * A volume of 1.0 is full volume, but I go to 2.0 to have a slightly wider range.

Thanks for reply, but I forgot say, that I want use only pjmedia and not pjsua. I know, there is function pjmedia_conf_adjust_rx_level and pjmedia_conf_adjust_tx_level, but I didn't use conference in my program. Thats the reason, that I want use pjmedia_aud_stream_set_cap function.
