Hi All- I've been using PJSIP on my work machine with no problems, but trying to run it on my home machine (Ubuntu 10.10) is giving me the following error when making a SIP call: pjsua_media.c Error retrieving default audio device parameters: Unable to find default audio device (PJMEDIA_EAUD_NODEFDEV) [status=420006] I've hunted around quite a bit for an answer to this and don't see a solution. No audio devices are seen by PJSIP, even though: ($:~/Downloads/pjproject-1.8)- aplay -L pulse Playback/recording through the PulseAudio sound server front:CARD=CMI8738,DEV=0 C-Media CMI8738, C-Media PCI DAC/ADC Front speakers rear:CARD=CMI8738,DEV=0 C-Media CMI8738, C-Media PCI 2nd DAC Rear speakers surround40:CARD=CMI8738,DEV=0 C-Media CMI8738, C-Media PCI 2nd DAC 4.0 Surround output to Front and Rear speakers surround41:CARD=CMI8738,DEV=0 C-Media CMI8738, C-Media PCI 2nd DAC 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=CMI8738,DEV=0 C-Media CMI8738, C-Media PCI 2nd DAC 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=CMI8738,DEV=0 C-Media CMI8738, C-Media PCI 2nd DAC 5.1 Surround output to Front, Center, Rear and Subwoofer speakers iec958:CARD=CMI8738,DEV=0 C-Media CMI8738, C-Media PCI DAC/ADC IEC958 (S/PDIF) Digital Audio Output And when I compiled, the sound backend was seen as "Unix". What do I need to do to enable sound? Thanks, Ryan -------------- next part -------------- An HTML attachment was scrubbed...
