Digital volume controls – PS Audio
https://www.psaudio.com/pauls-posts/digital-volume-controls/
Digital volume controls are the same in this regard, but a whole other story. They add nothing to the signal path: instead they rearrange the digital numbers to achieve a lower volume. This is simple to understand if you remember that each loudness level in a PCM digital system is based on a number – that number representing the level of the output signal – with …
Digital audio ouput - why no volume contr… - Apple Community
https://discussions.apple.com/thread/1214940
Most digital audio formats do not support encoding volume level as metadata, so there is no way to implement a standardized, global digital audio volume control for a standard S/PDIF output, period. There are only four bits available for this use in the standard & they are rarely used for metadata, especially in consumer gear.

With a digital volume control, the peak signal level is reduced, but the underlying noise remains the same -- consequently, there is a reduction in dynamic range. The degree to which this loss of dynamic range is a problem depends on the inherent noise level of the DAC.

Audio volume level problems can be solved by the introduction of audio level control into the digital path. One of the most common digital audio formats to use is the AES-3 signal. If you use AES-3 in your system you can install audio gain control in that stream to control the audio volume changes.
Digital output has volume control?!? How … - Apple Community
https://discussions.apple.com/thread/7937337
Answer: A: a digital signal is a lot of numbers (samples) with a value which is the value of the signal at the time of the sample. so a long line of numbers representing the audio signal. if all those numbers are lowered by X then you lowered the general digital audio signal volume. same deal with raising it.

DSP-based volume control of digital audio can be implemented via hardware (DSP in a chip) or software (DAW, media player). It performs multiplications on the digital audio data before the data is delivered to the D/A converter. In most cases, a DSP-based volume control will limit the dynamic range of the playback system.

The Optical Digital Audio Out jacks on Sony TVs are Fixed. NOTE: When using this type of connection the volume must be controlled by the home theater system or audio receiver; the TV remote control cannot control the sound. To control the sound output with the TV remote control, a composite audio connection should be used instead (if your TV has one).
