>Description:
My note PC(NEC VersaPro VY10F/BH-L) has sound device as following;
pcm0: <Intel ICH4 (82801DB)> port 0xe000-0xe03f,0xee00-0xeeff
mem 0xffaff400-0xffaff4ff,0xffaff800-0xffaff9ff irq 9 at device 31.5 on pci0
pcm0: [GIANT-LOCKED]
pcm0: <Analog Devices AD1981B AC97 Codec>
It seems recognized and work well, but sound dose not come out.
>How-To-Repeat:
Boot PC. and execute sound application. no sound from speakers,
nor from headphones.
>Fix:
My PC is implemented ac97 eapd in an inverted sense.
and some SONY note PC has same implementation(see kern/66422)
So I propose new kernel option to slove this irregular implementation.
