Could you please screenshoot exact menu options that you are able to choose ((Additional TLV Settings)?

Here we go.

Network --> LLDP --> Global Setup --> LLDP Enable (LLDP should be enabled by default) then Network --> LLDP --> Port Setup --> pick-up a Port and select "Operation" for that Port --> at bottom position there is "+Additional TLV Settings" which, once expanded, gives those sections:

• DOT1 TLV Settings
• DOT3 TLV Settings
• MED TLV Settings

So guys,  I bet option: "network policy" in MED TLV Settings (parnassus, your screenshoot from HP 1920). Here is link to other interesting, similar tread but with Comware LLDP-MED network policy:

Re: CISCO IP phone on HP 5130-24G-P​oE

Is this not the same LLDP-MED "network policy" ???

But really there is need that someone could test in reality for 1920 switch and LLDP-MED capable IP Phone!

Cheers!

The manual has these descriptions for those (per Port) Additional TLV Settings:

Just my educated guess...
The auto-qos for voice LAN doesn't do complicated stuff. It will just populate the COS value inside the VLAN-tag to some "better" value.  From range 0...7  it will pick 5 or above.
This will favour all traffic in voice VLAN....not just RTP but probably also stuff like firmware downloads.
