Cross-Platform Laptop Driver Suite

I need a full, production-ready set of drivers that make common laptop hardware behave identically on Windows, Linux and macOS machines from the three big vendors—Dell, HP and Lenovo. The scope covers every audio path (built-in speakers, external speaker jacks and the internal microphone array), the latest USB host controllers (3.0 through 4.0) and the integrated webcam.

My end goal is plug-and-play reliability: the moment the OS boots, the device must be recognised, configured and ready for user applications without manual tweaking. That includes WHQL-signed packages for Windows 10/11, ALSA-compatible modules for major Linux distributions (Ubuntu LTS, RHEL, Fedora) and notarised, kextless solutions for current macOS releases.

Deliverables
• Signed binaries and source code for each supported OS
• Clear build scripts or project files (Visual Studio, Makefile, Xcode as appropriate)
• A concise installation guide for each platform
• A one-page matrix summarising tested laptop models and confirmed working features

I will run acceptance tests on reference Dell, HP and Lenovo units; payment is released when audio playback/record, USB hot-swap and camera streaming all pass hardware diagnostics on every operating system listed above. If you have prior experience contributing to ALSA, CoreAudio or Windows Driver Frameworks, please mention it so we can dive straight into timelines.
