Upgrading to 2.6.27-gentoo-r7 from 2.6.26-gentoo-r4 using make oldconfig and building sound drivers in the kernel breaks alsa. Drivers cannot be detected by alsasound when booting with 2.6.27-gentoo-r7, but work as expected with the previous stable kernel: 2.6.26-gentoo-r4. Reproducible: Always Steps to Reproduce: 1.Copy .config from 2.6.26-gentoo-r4/ to 2.6.27-gentoo-r7/ 2.Run make oldconfig 3.Select sound drivers in kernel 4.Reboot Actual Results: alsasound fails to load, because it cannot find the kernel drivers: ================================================ # /etc/init.d/alsasound restart * Loading ALSA modules ... * Could not detect custom ALSA settings.

Did you run alsaconf after that reboot? Which version of alsa-{lib,utils} do you use?
(In reply to comment #1) > Did you run alsaconf after that reboot? Yes, but it cannot find any drivers or my card: modinfo: could not find module snd Running alsamixer gives: alsamixer: function snd_ctl_open failed for default: No such file or directory Which version of alsa-{lib,utils} do > you use? media-libs/alsa-lib-1.0.17a USE="midi python -alisp -debug -doc" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" -- Regards, Mick
Please compile all those sound drivers as modules and try again: "Please note that for ease of use, all examples show ALSA built as modules. It is advisable to follow the same as it then allows the use of alsaconf which is a boon when you want to configure your card."[1] [1] http://www.gentoo.org/doc/en/alsa-guide.xml
