What’s the problem of all sw controlled chips including “special” chips someone before was saying it’s better. But any how it’s hard to say something positive to this topic here it’s seems like religion. It’s in technology all ways how things are implemented. You drive car with software controlled throttle and mostly it works sometimes not (a video of a E car was shortly in internet). So we should not project from one implementation to all other’s.
And before I forget: volume is also IR controlled if someone sitting on the remote… or some other IR transmission occurs it can have the same result.
With these threads and this particular issue, it's like talking to a brick wall.
It's not about a design flaw, it's not about human error, and certainly not about any other type of volume control. Upstream digital or DSP-based volume controls also have nothing to do with this problem.
I also don't understand what you mean by "special" chips.
- A DAC chip always has the task of converting the digital data into analog.
- It does this without any intervention or modification of the digital data.
- This means that the data is always with a volume of 0 dB
be converted and issued. So in original volume!
That, and only that, is the initial state of any normal DAC chip.
If you then use the DSP function of the DAC chip to reduce the volume digitally before conversion, what happens if the chip is set to its initial state by something?
Exactly, 0dB volume.
Of course you can avoid the problem with hardware and software, but the necessary components would also have to be on the circuit board.
If a manufacturer uses this DSP function in the DAC chip for volume reduction (and again, it's not a volume control), you have to be aware of a potential problem.
