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.

Subject: Change microphone volume
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?
