Hi Russell,

Our radio exposes a PCM interface and we route it to the i2s bus on
our processor.

You're right. I do seem to have some alsa related errors when I start
linphonec. I'll dig into this.

I'm curious to know how you adjust the playback gain settings in the
linphone gui. I'm also using linphone on my ubuntu laptop and I don't
seem to see this setting. ( I just checked )

Thanks for your time!
