Alc271x Datasheet Here
Realtek ALC271X
The is a 4-channel high-definition audio codec designed primarily for laptop and desktop computers. It is part of the ALC269 series family and is commonly used in portable multimedia devices due to its high-performance digital-to-analog (DAC) and analog-to-digital (ADC) conversion capabilities. Technical Specifications
- Datasheet Fact: Partial. They are pin-to-pin compatible in LQFP-48, but the register sets differ. A BIOS update is required because the Verb IDs are different. The ALC269 has better SNR (93dB vs 88dB).
Critical Note from the Datasheet:
The ALC271X does not support 192 kHz sampling or 7.1 surround sound. It is strictly stereo line-out and stereo line-in/mic with a dedicated headphone amplifier. alc271x datasheet
In HD Audio mode, this pin goes HIGH to turn on an external amplifier (usually a cheap Class-D amp for laptop speakers). In AC’97 mode, this pin is a GPIO. Realtek ALC271X The is a 4-channel high-definition audio

Realtek ALC271X is a High Definition Audio Codec commonly found in laptop motherboards and small form-factor PCs. Because it is often used as a replacement part for board-level repairs, finding a clean datasheet can be tricky as they are frequently kept behind manufacturer paywalls or NDA. 1. Key Technical Specifications While specific revisions (like the ALC271X-VB6-CG
Power Management:
Features advanced power-saving modes suitable for mobile devices, allowing the codec to enter low-power states when not in use.
and ALC272 series. While precise datasheets for the "X" variant are often restricted, its documented features align with standard mobile HD audio codecs: IC Components Audio Channels: Supports multi-channel HD audio (typically 2-4 channels). Audio Fidelity:
