Internal speaker perfectly works, but headphone or lineout jacks have no audio output. Fix: The patch below will only fix Fujitsu C610, but just collapsing into void ad198x_patch(struct ac97_info* codec) { ac97_wrcd(codec, 0x76, ac97_rdcd(codec, 0x76) | 0x0400); } seems to be the better solution. Also backportable to older FreeBSD. (cd /usr/src; env TZ=GMT diff -u sys/dev/sound/pcm/ac97_patch.c{.dist,}) How-To-Repeat: With motherboards with AD1980 codec, and monitoring its LINE_OUT pins, play some audio. No audio output. SURR_OUT/HP_OUT pins will have output. These AD1980 pins may be wired in various ways to lineout/headphone/internal speakers, and some configuration (particulary laptops) may not have one of the output wired.
