Phone and Pulseaudio (Linux 64-Bit)

Hello,

I am seeing the following behaviour on two different versions of the Spark Client:

Spark 2.7.5.752

Audio device shows up in "Media settings" as

javasound:default [default]: 0

In Pulseaudio mixer I can see a seperate connection from Spark (shown as ALSA plug-in [java]) for every phone call I make, which is probably unnecessary. Otherwise it seems to mostly work correctly.

Spark 2.7.7.810

After logging in, console output shows a stracktrace starting with

SEVERE: Failed to register custom Renderer org.jitsi.impl.neomedia.jmfext.media.renderer.audio.PulseAudioRenderer with JMF.

java.lang.IllegalStateException: audioSystem

Only interface shown in "Media settings" is audiosilence. No sound at all.

As i saw Jitsi mentioned in the Stacktrace and I have it installed I tried that (latest nightly), and it worked flawlessly with Pulseaudio.

Possibly useful info about my system:

Debian GNU/Linux testing (stretch)

I'm grateful for any feedback regarding the topic. Thanks!
