I've rebooted today with kernel 2.6.19 (used 2.6.18 before). I have a Intel 945G/GZ/P/PL motherboard and a Intel hda on board soundcard (Alsamixer says "Card: HDA Intel" and "Chip: Realtek ALC260").
Look for the Bugs concerning the kernel and hda-intel drivers http://bugs.gentoo.org/buglist.cgi?quicksearch=ALL+alsa+hda For me alsa-driver (not kernel-alsa) did not work with kernel 2.6.19 too. I upgraded to kernel 2.6.20 and latest alsa-driver, and my problem was solved. -- gentoo-user@gentoo.org mailing list
