Hi Michael, Yes, you are right. If there is a single input/output device, pjmedia will prefer to use the device (see pjmedia's audiodev.c) because of better EC performance, that's why it chose the USB device. If you wish to change this behavior, you can use the audiodev's API to select the audio device you want in your application (see pjmedia_aud_dev_count() & get_info()).

It seams that the application takes always a device where Input and Output has the same name. In addition my app works fine with Polycom. So there seams not to be a difference between Mac Mini and Mac Book because I have such a device on Mac Mini which probably was the reason that it worked on Mac Mini. When I disconnect Polycom it does not work anymore. > > Regards Michael. > > > > --- On Thu, 1/20/11, Ming <ming at teluu.com> wrote: > >> From: Ming <ming@xxxxxxxxx> >> Subject: Re: OS-X coreaudio resample crash >> To: "pjsip list" <pjsip at lists.pjsip.org> >> Date: Thursday, January 20, 2011, 4:49 PM >> Hi Michael, >> >> I am a bit confused here.
