Syrinscape Player (Linux) - Error executing m_FMODChannel

Hi.
When i try to exit the Syrinscape Player (Linux, version=1.5.0-p1), the process stays alive. Syrinscape then generates a logfile until the Space of the filesystem run out (1,1 TB last time). The logfile is in ~/.config/unity3d/Syrinscape/Syrinscape Online Player/Player.log and increases about 10GB / minute in Size.

It repeats the line ./Modules/Audio/Public/sound/SoundChannel.cpp(397) : Error executing m_FMODChannel->stop() (The specified channel has been reused to play another sound. )
over and over again.

A normal kill (SIGTERM) does not work SIGKILL (Signal 9) does.

Any idea how i can fix this?
