Hi Simon,
Thanks for the input. That may explain my issue. I'm using mediastreamer2 directly (with no linphone) and ms_snd_card_set_level() does not adjust the volume.
How then does linphone adjust the playback and capture volume? Do I have to use ALSA directly?
Thanks
Denny

They appeared after an upgrade of libasound (about one year ago), without any change in linphone. Alsa configuration is something very obscure to me. The warning indicates that the volume control mediastreamer2 can do on the sound card won't work, however it is not used in linphone.
