This bug is 6 years old and no reply. Has linphone been abandoned? Anyway, exactly the smae thing is still happening:
$ linphonec ALSA lib conf.c:5001:(snd_config_expand) Unknown parameters 0 ALSA lib control.c:1373:(snd_ctl_open_noupdate) Invalid CTL default:0 ALSA lib conf.c:5001:(snd_config_expand) Unknown parameters 1 ALSA lib control.c:1373:(snd_ctl_open_noupdate) Invalid CTL default:1 ALSA lib pcm_dsnoop.c:638:(snd_pcm_dsnoop_open) unable to open slave ALSA lib pcm_dmix.c:1099:(snd_pcm_dmix_open) unable to open slave Linphone has only worked once on Debian, many years ago. I have always had to give up and turn to ekiga before. I had hoped that it might have been fixed meanwhile, but it seems not :-(
