Hi M?rten, You are right. However, after consulting the code author, it is actually on purpose to maintain the default iOS/MacOS latency, rather than applying PJMEDIA_SND_DEFAULT_REC/PLAY_LATENCY (perhaps rather high for iOS/MacOS standard :) So meanwhile, we'd suggest you to explicitly call pjmedia_aud_param_set_cap()/pjsua_snd_set_setting() after instantiating audio dev stream to change the latency. Sorry for that and thanks for the report+patch. BR, nanang On Fri, Mar 15, 2013 at 9:47 PM, M?rten Wikstr?m <marten.wikstrom at keystream.se> wrote: > Hi! > > There is a bug in coreaudio_dev.c.
