Audio — Realtek ALC236¶
| Item | Value |
|---|---|
| Codec | Realtek ALC236 (10EC:0236) |
| HDA controller | Intel 8086:A348 |
| Layout | layout-id = 15 on PciRoot(0x0)/Pci(0x1f,0x3) |
| Driver | AppleALC 1.9.9 (with Lilu) |
| Verified | Sonoma 14.8.9: speakers, headphones, microphone. Sequoia 15.8.2: speakers and microphone (headphones not separately tested) |
AppleALC gets the codec from the HDA controller and the layout decides which pin configuration is used. Layout 15 matches the ALC236 wiring on this laptop: internal speakers, headphone jack and the internal microphone. Layout 5, which is commonly suggested for 236 codecs, is not correct here.
Microphone gain¶
The internal microphone works on both systems but only at high input volume. At the default gain it is effectively silent — measured at −69 dBFS RMS with a sound source next to the machine, versus −38.9 dBFS at 100 %. Setup steps and the Sonoma measurements are in Sonoma hardware support.
Reusing this on another laptop¶
AppleALC itself is generic, but layout-id 15 is not. If your machine has an
ALC236, check the pin configuration in AppleALC's
layout list
and try the layouts listed for it — the codec name alone does not tell you which
layout your board wired. A different codec needs a different layout, and often
its own verb fixes.
Nothing about this layout should be presented as universal AppleALC support.
