LDAC profile unavailable for Sony WH-1000XM3

[easyrider]

Is this to possible to select LDAC here?

Currently only: SBC, AptX, AptX HD ara available

I've read:

LDAC only works when you sending audio from PulseAudio (PA play as source, your Headphone/Speaker play as sink).

but not completely sure how to setup it.

    Profiles:
        headset_head_unit: Headset Head Unit (HSP/HFP) (sinks: 1, sources: 1, priority: 30, available: yes)
        a2dp_sink_sbc: High Fidelity Playback (A2DP Sink: SBC) (sinks: 1, sources: 0, priority: 40, available: no)
        a2dp_sink_aptx: High Fidelity Playback (A2DP Sink: aptX) (sinks: 1, sources: 0, priority: 40, available: no)
        a2dp_sink_aptx_hd: High Fidelity Playback (A2DP Sink: aptX HD) (sinks: 1, sources: 0, priority: 40, available: yes)
        off: Off (sinks: 0, sources: 0, priority: 0, available: yes)

My distro: Linux Mint 19.3

Edit: I've tried:

$ pactl set-card-profile 2 a2dp_sink_ldac
Failure: No such entity

Solution:

I've probably managed to get LDAC working - however the other options doesn't work now - I'm not sure why (previously aptX HD) so I cannot compare but sounds awesome

I've updated pulseaudio to 12.2-2 (mint 13) and installed using option: A. build for PulseAudio releases (e.g., v12.0, v12.2, etc.)

Verfied using a Sony's Headphones app:

Rate of transmission: 1.20 KB/s (Blueman 2.0.5)

Looks like it's working now.
