Hello,
Yes, the DisplayLink DL-6950 chip supports audio over HDMI, DisplayPort, analogue, and digital outputs.
Instead of confusing the users with 5+ outputs in the audio mapper, only one is added and audio routed to all. This also allows users to use an HDMI audio for an AV amplifier whilst using another output type simultaneously. This would not be possible with multiple entries in the audio mapper.
Some device manufacturer use headphone privacy which disable all other outputs when headphones are connected.
You will have an USB audio device in the audio settings. If you don't, there would be an issue with the audio device or device driver. Would you check?
Kind regards,
Alban
