Re: [Linphone-developers] playbackga command in linphonec gives error "Cannot understand this" (linphone 3.7)

[Henrik Pauli]

This issues has nothing to do with the sound device, and 3.7 works more reliably with ALSA than with Pulseaudio, even when PA is running.

The command is called playbackgain, the help text is just truncating it.

The help is *amazingly* helpful even in 3.9 </sarcasm>:

linphonec> playbackga
'playbackga': Cannot understand this.
linphonec> playbackgain
Syntax error.
Adjust playback gain.
linphonec> help playbackgain
Adjust playback gain.

if you are running pulseaudio try using the pulseaudio interface.

also set your udp source port to random.

Hello,

I'm trying to figure out why the playback command in linphonec is
giving me the error "Cannot understand this"

I'm using linphone 3.7 and I've been trying to dig through the source
to see if there is perhaps some feature that I'm missing. So far I
haven't found anything.

Any hints would be greatly appreciate as far as what to try next.

Thank you,

Davis
