Perhaps if MUTE is held across power cycles, when the unit is powered on and mute is engaged, the display could flash a message that mute is engaged, or maybe just the word MUTE in big letters.
Either flashing, or just on screen for something like 5 seconds and then disappear.
I have also mentioned the mute button to Oppo on the remote app... IIRC, the mute button always has an "x" on it.
I suggested if possible, to make the mute button show an x only when mute is engaged, and then remove the x when the mute function is not active.
I like both of these ideas. Youre right, the button does always have the X on it. Toggling the X may be the easiest solution.
Do you have speakers connected as well? How do you feel about the mute on power cycle? I'm just wondering if Im the only person that thought the way it works wasnt ideal. The unmuting isnt a huge issue but the few times i forgot to check I had the volume pot up a fair bit and got a bit of a jolt when music started playing!
Personally I would rather have the MUTE carry over across power cycles. I have had at least one instance of it blasting me away when powering on from previously in mute state.
I was happy to find that it didn't damage my speakers that I know of.
HasturTheYellow makes a very good point about it confusing some users into thinking the amp has gone tats up when not realizing it's muted.
However, another idea which may be even better, is to implement a "power on volume level" in the amps menu.
So then whatever number the user decides to plug into that setting, the unit will always power on at that volume level, despite what the volume was when powering off.
Their latest media players do have that feature already, and I think they could also implement it in the HA-1 if they wanted to.
