I booted kernel with modprobe.blacklist=snd_soc_rl6347a and I put "blacklist snd_soc_rl6347a" in /etc/modprobe.d/blacklist.conf. I even tried to recompile the kernel without that module, but there is no option in "make nconfig" to disable it, while adding "# CONFIG_SND_SOC_RL6347A is not set" to the config doesn't help because it keeps showing CONFIG_SND_SOC_RL6347A=m in "make nconfig" if I search for it with F8. I attached another log with modprobe.blacklist=snd_soc_rl6347a plus modprobe.d entries: https://bugzilla.kernel.org/attachment.cgi?id=189361 Thanks, Niccolò Belli
