DP sound has gone on UHD620

Recommended Posts

Hi there,

I've got gb brix gb-bri7-8550 with 8550 cpu and ALC255 codec. Also have uhd4k display with speakers, connected to it via dp. Everything was working fine for months (or even years) till now. Cannot understand when and what was the reason, but now dp sound on the monitor does not work. There's just no device in the settings. LineOut audio is working well though.
I didn't use sound on it for several months, but installed updates etc so cannot tell when it exactly happened.
I use clover 5118, latest weg/lilu/applealc, 10.15.5. The "Devices" section in the config is simple:

        <dict>
                <key>Audio</key>
                <dict>

                <key>Properties</key>

Yes, but it started on 10.15.4, or even earlier. Cannot tell exactly when. Now I have everything updated to the latest version.
