Hi, I finally succeeded to manage several audio devices simultaneously (eg. one call to a first audio device and another call to the second audio device), using splitcomb as described in pjsip wiki (https://trac.pjsip.org/repos/ wiki/FAQ#multi-snd). However, I see some increasing delays for voice transmission now: there is about 0,5 second between speaking and hearing. This is easy to check with audio loopback, with such delay between the microphone and the speaker of the same audio device. I guess this is related to the use of reverse channel in splitcomb... Does anybody know how this delay could be suppressed with splitcomb? If not, is there another way to handle multiple audio devices simultaneously without impact on audio delay? Before using splitcomb, the audio loopback was nearly immediate. Regards, Thibault
