Huh? I don't see any mention of HDMI output nor Analogue output, only DP-alt mode. I guess that uses the HDMI method of delivering digital audio, but this page doesn't seem to be particular to this board at all.

Thanks for flagging this — you're right that the audio-usage page is currently a generic common MDX and does not actually vary by board.

For the record, A7S hardware exposes:

• No HDMI port (only USB‑C 2 USB 3.2 with DisplayPort Alt Mode)
• No 3.5mm headphone jack
• Bluetooth audio (Wi‑Fi 6 + BT 5.4 module)

So the only available audio output paths on A7S are Bluetooth audio and DP Alt Mode digital audio over USB‑C 2. The "Headphones > HDMI" priority in the current page does not apply to A7S.

I've prepared a docs-only fix that adds a board-specific :::warning callout at the top of the A7S audio-usage wrapper (zh + en) so the actual A7S audio paths are visible before the generic common MDX content. PR: tangzz-radxa#43

The common MDX itself is left untouched, since other boards in the same family (A7A in particular) actually do have all three paths. A follow-up to make the common MDX board-props aware could be a separate, more structural change.

Closing this once PR #43 lands, but happy to keep the discussion open if you want a more structural refactor of the common MDX.
