Latest working kernel version: 2.6.23-r3 (but with alsamixer problem, see below) Earliest failing kernel version: 2.6.25-r6 (started with sound, but then no more sound) Distribution: Gentoo Hardware Environment: AMD64 nvidia ALC662 rev1 Software Environment: Problem Description: With kernel 2.6.23-r3 alsamixer did work only with one line in the file /usr/src/linux/sound/pci/hda/patch_realtek.c masked as comment: /* { .id = 0x10ec0662, .rev = 0x100101, .name = "ALC662 rev1", .patch = patch_alc662 }, */ Without this, alsamixer reported "alsamixer: function snd_mixer_load failed: Invalid argument" when unmuting. With kernel 2.6.25-r6 the alsamixer error was gone. But after a while there was no more sound, and this is still the same with newer kernels. I tested with kernel 2.6.28_rc6: alsamixer looks good, mplayer looks good, but there is nothing to hear. alsa-info.sh produces the following output: upload=true&script=true&cardinfo=
