Package: linux-image-3.16.0-4-amd64 Version: 3.16.7-2 I have an Asus X205TA (Intel Atom Z3735F) Bay Trail notebook and its on-board sound device is not detected. Apparently, it uses a Realtek RT5640 chip, but the relevant kernel modules (snd-soc-sst-baytrail-pcm, snd-soc-sst-byt-rt5640-mach, etc.) are not being built. Hendrik
