💖 drm_detect_monitor_audio(9) 💖

okay so bestie, welcome to the drm_detect_monitor_audio page — it lives in the Kernel API Manual, and it's literally the vibe check for whether your monitor can do audio 🎀

✨ NAME ✨

drm_detect_monitor_audio — check monitor audio capability 🎧

🌸 SYNOPSIS 🌸

bool drm_detect_monitor_audio (const struct edid *edid );

🦋 ARGUMENTS 🦋

  • edid — the EDID block you want to scan, bestie. that's the thing we're snooping through 🔍

💅 DESCRIPTION 💅

okay so here's the tea ☕ — for this to work, the monitor should have a CEA extension block. that's the prerequisite, no cap.

now the actual logic, and it's kind of iconic:

  • if the monitor has 'basic audio' but there are no CEA audio blocks → it's 'basic audio' only. that's it. that's the whole vibe.
  • if there's any audio extension block and a supported audio format → we assume at least 'basic audio' support, even if 'basic audio' isn't even defined in the EDID. yeah, we're being generous like that 🫶

⭐ RETURN ⭐

True if the monitor supports audio, false otherwise. simple as that 💫
