Step-by-step explanation:
In the Linux kernel, when adding support for a sound device, recompiling the kernel is typically necessary. The Linux kernel is the core component of the operating system that manages hardware, software, and system resources. When adding support for a new hardware device, such as a sound card, it usually requires modifying the kernel configuration and rebuilding the kernel to include the necessary drivers and modules for that specific device. Recompiling the kernel is necessary to incorporate the changes and enable the new functionality within the operating system.
