102 This adds support for a dummy/nocodec machine driver fallback
103 option if no known codec is detected. This is typically only
104 enabled for developers or devices where the sound card is
105 controlled externally.
106 This option is mutually exclusive at build time with the Intel HDAudio support.
107 Selecting it may have negative impacts and prevent e.g. microphone
108 functionality from being enabled on Intel CoffeeLake and later
109 platforms.

119 When these files are more recent than the kernel, the kernel
120 will handle the functionality it supports and may report errors
121 during topology creation or run-time usage if new functionality
122 is invoked.
123 This option will stop topology creation and firmware load upfront.
124 It is intended for SOF CI/releases and not for users or distros.

168 though there is a codec detected on the real platform. This is
169 typically only enabled for developers for debug purposes, before
