Here is the comparative table for your kernel parameters vs those of gentoo-kernel 5.4.64 and my last tried configuration in gentoo-sources-4.19.86: --------------------------------------------------------- CONFIG | 4.14 | 5.4.64 | 4.19.86 SND | y | m | y SND_TIMER | y | m | y SND_PCM | y | m | y SND_HWDEP | m | m | y SND_DRIVERS | y | y | y SND_PCI | y | y | y SND_HDA | m | m | y SND_HDA_INTEL | m | m | y SND_HDA_HWDEP | y | y | n SND_HDA_RECONFIG | y | y | y SND_HDA_CODEC_REALTEK | m | m | y SND_HDA_GENERIC | m | m | y SND_HDA_CORE | m | m | y SND_SPI | y | n | absent The last option is absent from my config file of gentoo-source-4.19.86. However, it seems that in gentoo-kernel-5.4-64 it also means nothing because it leads to an empty section even if it is chosen. So, it seems that at least the configuration for kernel 5.4.64 should work. However, it does not.
