Hi, I don't think so, since pjsua will automatically manage the resampling 48KHz <-> 8KHz as the same case with default clock rate 16KHz. Please check with: - command 'cc 0 0' in the pjsua prompt, see if you can hear loopback audio. - sndtest, e.g: "sndtest --id 0 --rate 48000" and send along the test result.
