I compiled and tested it successfully. I've used an external USB sound, everything is true. I've attached two external USB sound card now. and I want to use two simultaneous pjsua apps so that each one work with one of this USB sound cards. I have edited /etc/modprobe.d/alsa-base.conf as following: options snd-usb-audio index=0,1 options snd_bcm2835 index=2 I can see two usb sound card by using "aplay -l" with index of 0 and 1. I can also see it in "cat /proc/asound/cards". It shows my two USB sound cards. But when I run pjsua (./pjsua-armv61-unknown-linux-gnueabihf --capture-dev 1 --playback-dev 1) it runs successfully and shows that usb sound card 1 is selected: pjsua_aud.c Set sound device: capture=1, playback=1 pjsua_app.c .Turning sound device ON pjsua_aud.c .Opening sound device PCM at 8000/1/20ms but USB sound card 0 is active yet and audio heard in it, and USB sound card 0 doesn't work anyway. Has anyone any idea?? Help me plz -------------- next part -------------- An HTML attachment was scrubbed...
