Nvidia Shield volume too high on Polk MagniFi MAX

I have an Nvidia Shiled TV what connects to the Polk MagniFi MAX's HDMI1 and the the soundbar is connected to my TV's HDMI. I enabled the HDMI-CEC volume control on Shield. With this option, the Shield's volume is maximized and if I adjust the volume with the Shield's remote it adjusts the soundbar's volume over HDMI-CEC. My problem is the volume is too high with the soundbar's minimum sound level. I can't lower it more, because then it switch to mute. Nvidia say it is not Shield's fault ask Polk. They say "SHIELDs volume by default is like 95% of other devices on the market".

That sounds like a design flaw.Political Correctness'.........defined

Thanks Kex, I tried what you advised, but no success. But I checked all settings on Shield, soundbar, TV and I found something interesting. Maybe the TV cause the problem.
My setup:
The orange lines are the HDMI cables.
So the strange thing is the Shield is connected directly to the soundbar and the soundbar forwards the signal to the TV. I tought only the picture and the soundbar plays the sound. But on TV there is a VIERA Link (HDMI-CEC) settings menu, where there are two settings for sound: TV or Home cinema. If this is Home cinema the Polk sounds if TV then the TV's speaker. So maybe the sound goes to the TV and then back to soundbar. But there is no HDMI-ARC connector on my old Panasonic plasma.
Is there any option on soundbar to not forward the sound to the HDMI OUT? I can't see anything similar in users manual. -
I tried to disconnect the TV from soundbar, SHIELD still connects to the soundbar and there is no sound. If I connect the TV back, the sound comes back. Why does it need the TV to sound? I guessed the sound goes to the soundbar it process it and only the picture forwarded to the TV.

The volume is controlled over HDMI-CEC with Shield remote mainly. The strange thing if I lower the volume with Shield remote (what is BT connected) the volume OSD is appears on TV (the TV's own OSD). This is why I started to suspect the TV is sinner.
If I control the volume with the TV's remote or the soundbar's there is no difference.
I have optical cable, but it doesn't support 5.1 PCM audio. -
The firmware is up to date on soundbar and Shield too.
If I connect Shield directly to the TV via HDMI and the sound goes from the TV to the soundbar over optical cable the situation is the same. In this case I can lower the Shield's system volume (HDMI CEC volume is disabled) but with Dolby and DTS passthrough the volume level is the same as directly connect Shield to soundbar with HDMI.
Works only HDMI or only optical or HDMI+optical too. But over optical the LPCM 5.1 not works. And I have to connect the cable box with the optical to the soundbar.
I can't pair the Shield's remote with the soundbar, because it not uses IR but BT.
