Hi, I am using the PJSIP version 2.1 on Ubuntu. This Ubuntu is basically a VM which I am running on windows 7. When I am trying to run the application auddemo on Ubuntu then it says Sound device count = 0 No devices found But if I ran command to Display all soundcards and digital audio devices $ arecord -l Then it gives result as **** List of CAPTURE Hardware Devices **** card 0: AudioPCI [Ensoniq AudioPCI], device 0: ES1371/1 [ES1371 DAC2/ADC] Subdevices: 1/1 Subdevice #0: subdevice #0 Can anybody tell me why PJSIP is not able to recognise the audio device, Is there any connection of using ununtu on VM ?
