I don't see anything wrong in the log, although if there are lots of
Master/sound underflow errors that would indicate your processor can't
keep up, seems very unlikely. Your default setup is using PJSIP's MME
drivers. I think the only other Windows option is to use portaudio,
which you can do by putting the following lines in your config_site.h file.
#define PJMEDIA_AUDIO_DEV_HAS_PORTAUDIO 1
#define PJMEDIA_AUDIO_DEV_HAS_WMME 0
Are you using a headset device? If not, then when you do cc 0 0 you will
get echo, which the AEC will try to suppress. Maybe that's the source of
your "metallic" sound?
You can also test by playing a WAV file to speaker and recording mic to
a WAV file, using pjsua options.
