FreePBX 2.11.0.38 MOH no sound

I am runnng asterisk 11.13 and freepbx 2.11.0.38

Music on hold does not work.In the CLI I see that it has started but I get no sound.

The only hint I got is:

SetMusicOnHold application is deprecated and will be removed.

I don’t know if this is the cause but I know for sure that audio files are fine sine I can hear them as announcements.

Is it a known issue ? Do I have to upgrade to 2.12?
