Sophon developed end-to-end audio support for the qcs6490-radxa-dragon-q6a platform, focusing on firmware and topology integration within the NVIDIA/linux-firmware repository. Their work involved creating and packaging ADSP firmware, including binary and JSON configuration files, to enable audio routing and processing tailored to embedded systems. Leveraging expertise in audio driver development and firmware engineering, Sophon ensured the solution was platform-ready and configurable for various ADSP domains. The implementation addressed hardware enablement needs, delivering a feature-complete firmware package that supports audio functionality from initial configuration through to field deployment, demonstrating depth in embedded audio systems and low-level firmware development.
