Uncompressed or Dolby Digital?

No, it supports 5.1 24/48khz Dts lossy, and 5.1 18-20bit 48khz DD lossy. It does not support incompressed 5.1, as that would exceed the capacity of the output.

I know it isn't all just to be passed as analogue. In fact, there are some, extremely rare though they are, components that pass 192/24 PCM in stereo via s/pdif-toslink - why wouldn't it do 48/24 5.1?

The bandwidth of 2.0 stereo 24/192khz would not be exceeded on toslink or coaxial. However anything over two channels would exceed the bandwidth of the output.

As for Bass Management with 96/24 LPCM 2.0, you are mistaken. It is definitely dependent on the component for sure. If it can handle, it will do bass management, if it can't it won't. My Denon DVD-2200 universal player has a setting that allows me to add LFE to a 2-channel signal, be it 96/24 or otherwise. My Sony SCD-XA9000ES does this with 2-channel SACDs as well.

Well actually I am not. A 2.0 stereo signal would not have a LFE channel to bass manage. A 2.1 signal would. There is a huge difference between using DSP's that insert a filter to channel the bass below X frequency to the subwoofer and a LFE channel. A LFE channel has to be created and monitored, a filter(or DSP based crossover) just channels whatever low bass frequencies that are in the stereo signal to the sub. Dolby surround (2.0 stereo) does not have a LFE channel, but filters are used to direct the low bass to the subwoofer.

You are not adding anything, you are redirecting what is already there at X frequency to a sub. A LFE channel is created in the studio, and does not require a filter at all except that which the encoder imposes.

However, for whatever reason, my Sony DA4ES AVR will not apply bass management (or PLII or dts:neo or any other processing) to any 96/24 signal.

It probably does not have the processing power to handle signals over 48khz
