Use an oscilloscope to see if data is moving between the codec and the chipset.
No. Realtek has discontinued the ALC271X in favour of newer codecs (ALC255, ALC256, ALC3204). However, remaining stock is still available through electronics distributors. alc271x datasheet

Handles standard PC audio functions, including stereo speaker output, internal microphone arrays, and jack sensing for front-panel headphones. Sourcing and Safety If you are looking to purchase or replace this chip: ALC271X-VB6-CG.pdf - IC Components Always refer to the original manufacturer documentation for
The silicon is designed to handle hardware-level acoustic echo cancellation (AEC), noise suppression (NS), and beamforming (BF) technology. This makes it ideal for the VOIP applications and video conferencing tools that define modern remote work. Common Pin Configuration (Pinout)
The ALC271X is supported by the driver (specifically snd-hda-intel and snd-hda-codec-realtek modules). However, its integration has a colourful history of quirks and workarounds.
Often patched using the open-source AppleALC kernel extension alongside Lilu, typically utilizing specific layout IDs (such as Layout 3, 11, or 12) to correct headphone jack sensing and internal microphone switching. 5. Typical Application Circuitry and Troubleshooting
