Error on startup: player_wrk.pid no such file or directory

I recently came in contact with a friend running Volumio on hi Raspberry Pi Model B with Hifiberry DAC. The sound is really nice so I decided to equip my Pi with a Hifiberry DAC too and install Volumio.
I followed the install guide from the website, but on startup I get an error saying:

Startpar: service(s) returned failure: trancientlog …cat: /run/player_wrk.pid: no such file or directory

I searched the forums and found another guy having the same issue in February this year. Unfortunately no solution was posted.
Does anyone know where this is coming from and how I can solve it?
