== Notes and version constraints ==
* The guides apply only to Raspberry Pi OS (Raspbian); other distributions require manual adaptation.
* If noise or no sound through the 3.5 mm jack: reinstall the driver and/or restart the wm8960-soundcard.service.
* Kernel version determines which driver branch to clone: kernel &lt; 5.0 → rpi-4.9.y; kernel ≥ 5.0 → main branch. Run only one of the two.
* On 64-bit systems, adding arm_64bit=0 to /boot/config.txt may be required; then reboot and reinstall the driver.
* The headphone jack uses the 4-pole OMTP standard; CTIA headphones may have no mic-channel output.
* No external microphone input pins exist; recording is only possible via the onboard MEMS microphones.
* For Raspberry Pi 5, a fresh Bookworm OS and a clean SD card may be needed; exact steps depend on your system configuration.
