Hardware: ASUS VivoBook X513EA Audio Codec: Realtek ALC256 (HDA Intel PCH) Ubuntu Version: 24.04.3 LTS (Noble) Kernel Tested: 6.14.0-1011-oem Result: Built-in microphone still not working
Verification details: – Confirmed using alsamixer that both “Internal Mic” and “Internal Mic B” appear under Capture view. – Both were unmuted and raised to ~80%. – Tested with arecord -f cd -d 5 test.wav and aplay test.wav → no audio recorded. – “Headset Mic” input works normally (tested separately). ALSA Info: http://alsa- project.org/db/?f=4b96829b52f7b19fdd003c66b11818ceaabb693c Additional technical note: The codec dump shows two possible mic pins: – Pin 0x19: “Internal Mic” (analog) – appears unused. – Pin 0x1a: “Internal Mic B” (digital array mic) – likely the actual built-in mic connection. It seems the fix introduced in 6.14.0-1011-oem remaps only pin 0x19, whereas this VivoBook X513EA uses pin 0x1a for the internal mic.
