@nicegirl05, no it does all formats. Its not specific to HDMI, its just that HDMI by default can produce the PCM stream specification to passthrough newer digital formats.
Older formats use a 16bit 48k 2 channels PCM stream to passthrough DTS-Dolby, the newer stream is 16 bit 192k 8 channels (if I remember right) *.
You can even read on wiki that SPDIF was updated to passthrough all formats, but you do need 16 bit 192k 8 channels.
Representing Formats for IEC 61937 Transmissions | If you had HDMI 1.2 or less, not really different to legacy SPDIF in terms of formats.
* This appears to be correct, DTS-HD MA is ~24.5mbps, 16 bit 192k 8 channels is also ~24.5mbps, not the ~37mbps 24bit size.

@Lucky8, "Can you take a 50Gbps link and have 8K but only offer 8 Channel per link?" yes only 8 channels, HDMI EDID wont allow you to set more *.
In terms of digital out, Realtek only have SPDIF, same for Creative, others, no HDMI. So should we be stuck with 2 channels?
44K has issues, if you look into it, something to do with analogue aliasing I think, 48K suffers a bit.
If you have HDMI 2.1+, it specifies it can do up to 32 channels, but that's with HDA, so 32 x 48k 24bit @ ~37 mbps. Still can't set 32 channels.
* Plus you can't output more than ~37mbps when attached to HDA (which a GPU is).
Like with my AVR comment, would you prefer PCM to DAC and analogue amp, output then headphones, or digital direct to headphones?
If headphones where like my 'Digitally Managed Audio System', it would be down to the headphones how good it sounds.
A PowerDAC in this situation can attenuate the PCM input dB to prevent voltage clipping.
Also a 'How power can you supply?' handshake is needed, for settings.
