I am controlling Marantz SR5005 receiver using fire tv remote. The remote correctly switching on, mute, volume up/down etc. But I have a problem with how much volume increase/decrease when you keep pressing the up or down button. when you keep pressing, it is supposed to keep increasing or decreasing, but it does not, it increases one time only. So I have to tap multiple times to increase or decrease. For each tap, it would increase very small amount may be 0.25 db. The increments are very small, so it almost unusable. At the same time, If I increase or decrease volume by voice command , it correctly increases or decreases by 10db. In the settings, I have set the increments to highest number, so voice command works correctly. But the same settings are not used when you tap the button. Ideally we should not tap, instead keep pressing the button should work. Is there any fix for this problem?
