HDMI ARC - change increment number

[M1chyCZ]

Hi everyone,

I have KD-49XG8096 (Android TV) and I just bought Creative Stage 2.1. They are connected via HDMI (ARC). Once I increment volume on TV the volume is increment by 3. The volume on soundbar is incremented by 1. Does anybody know how to change the increment number on TV to lower number? 

Thanks,
Jan

TV works on a volume base from 1 to 100, don't know your soundbar. What you see is the equivalent volume of the soundbar in hundreds unit
