Hi guys, I tied to configure volume of sound device with the following
source code (with pjmedia api), but isn't working. How can I implement this
feature? Thanks in advice

pjmedia_aud_stream *pjmediaAudStream;
pjmediaAudStream = pjmedia_snd_port_get_snd_stream(snd_port);

// Volume setting is an unsigned integer showing the level in percent.
unsigned volToConfigure = 100;
status = pjmedia_aud_stream_set_cap(pjmediaAudStream,
PJMEDIA_AUD_DEV_CAP_OUTPUT_VOLUME_SETTING, &volToConfigure);

if (status != PJ_SUCCESS) { return status; }

pjmedia_aud_stream_set_cap return PJ_SUCCESS but the volume isn't
configured. Thanks in advice.

Best Regards

On windows the same source code works, on linux with alsa driver isn't
working.
