cannot change songs when connected to dac

• iphone 7plus, ios 12.1.4

when playing  a playlist locally on my iphone, no problem I can select another song  from the current playlist but when playing from my iphone to my DAC connected to the network, impossible to manually select another song  (except next/previous song buttons that still work)  even changing to another  playlist is not possible. workaround : i switch to local  iphone listening, change song and switch back to the dac

It looks it was due to the spotify plugin on my Dac (boss/volumio). I uninstalled/reinstalled and this seems to work
