TeamSpeak mutes Spotify

I do not know if this is intentional or not however I do not see an option to disable it anywhere to I will assume it is an unwanted feature or a bug. When connecting to server TeamSpeak will mute Spotify's audio stream. This only happens on Linux, I was using Ubuntu specifically. You are able to go into the audio settings in Ubuntu and click the toggle again to turn the audio back on however as soon and another audio stream comes into play TeamSpeak will cut off Spotify again.

This is not a TS bug.

When using Pulseaudio TeamSpeak will lower other applications voice because it has the role "Phone" for Pulseaudio.
The sound is lowered because Pulseaudio thinks you are in a call and by design a call lowers everything else.

To get this sorted please check in /etc/pulse/default.pa if following line exists

Code:

---

load-module module-role-cork

---

In case it does delete that line and restart Pulseaudio.
