Why does my soundbar reset its volume level every time I turn it on?

Alto 8 rests its volume every time you turn your system on. Here is the way the sound bar resets its volume:

Volume status
LED Display
Volume Memory

2. Last Volume <5 ,will go to Volume 5 when power on.
3. Last Volume>25, will go to Volume 25 when power on.

Despite being connected to the TV via HDMI ARC, I am not able to increase or decrease the volume on the sound bar using TV remote.

2. In the TV setting -> systems, ensure that CEC controls are active.
