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
:-(
