> Sure enough a dist-upgrade to current testing has enabled me to use Blink. It seems like a very nice application. I do have a question about audio and cpu usage though. When blink is idle, not on a call, it still uses considerable CPU both in blink, and via pulseaudio apparently recording and mixing zeros, this is with pulse audio on a current up to date Debian testing system.

We are aware of this issue if PortAudio is being used. We ran into some issues if the device was closed on Linux systems, and its currently not closed. If using ALSA alone this does not seem to cause high CPU usage. It does, however, cause high CPU usage when portaudio is used.
