[Can't fix. Hardware problem] The audio amp POP
Posted: Wed Mar 11, 2020 9:21 pm
I was happy to live with this amp pop (whenever the amp is turned on it pops, so there are pops at the beginning of RX and beeps) but I got some audio adapters so I can plug in headphones and wow is that pop hot. It's a good hard thump on the speaker.
So I'm thinking again that there must be a way to make that not happen (even if the OEM firmware does it too). Is it possible there's garbage data in a buffer when the amp is turned on, so that it's actually just playing that data? Could the amp be turned on just after we start feeding sound into it, so that the level is being held when it's coming up?
If it's really not possible to fix I guess that's what we get, but it seems like it should be possible.
Alternatively, how much power does the amp draw if we leave it on all the time and nothing is being fed into it?
