Please revert src/sys/dev/sound/pcm/ac97.c back to 1.43, these changes mess up the volume control on my
audigy 2 card. It seems the struct ac97mixtable_entry.bits field isn't getting properly
setup.

I'm not sure what you're doing with this code:

for (k = 0; j != 0; k++)
	j >>= 1;
for (j = 0; k != 0; j++)
	k >>= 1;
if (j != 0) {
	codec->mix[i].enable = 1;
#if 0
	codec->mix[i].bits = j;
#endif
} else
	codec->mix[i].enable = 0;
