The only minor annoyance I'm experiencing now, is a large amount of debug output from something in kernel log when audio is played on the system: writing to lpe: 00000000: 01 01 01 01 00 00 08 00 ff ff ff ff 55 00 00 00 ............U... writing to lpe: 00000000: 01 01 01 01 00 00 1a 00 ff ff ff ff 75 00 12 00 ............u... ...

That's enabled via dynamic debug so that's rather a configuration issue than a kernel problem?

Do you have any suggestions on how to disable it?

My kernel is compiled without DYNAMIC_DEBUG, DEBUG_FS and other debug features, so I don't understand why all this debug output is flooding the kernel log.

It's a minor issue, but it would be nice to get rid of it.

I don't see it so it's definitively a config issue. I use

make defconfig

scripts/kconfig/merge_config.sh .config base-defconfig sst-defconfig  hdaudio-codecs-defconfig

with all 3 defconfigs fetched from https://github.com/thesofproject/kconfig
