Hello,

After installing 4.3-RC1 on a new system based on the Gigabyte GA-7ZX
motherboard, which includes an ES1371 audio chip, the pcm driver
fails to detect the AC97 codec properly:

pcm0: <AudioPCI ES1371> port 0xd000-0xd03f irq 10 at device 14.0 on pci0
es_init
es_init pre ac97 2.1
wrcodec addr 0x26 data 0x0
wrcodec addr 0x0 data 0x0
rdcodec addr 0x0 ... loop 1 t 0x1000 x 0x40000000 loop 2 t 0x5000 x 0x70000 loop 3 t 0x1000 0x40000000 ret 0x0
rdcodec addr 0x7c ... loop 1 t 0x1000 x 0x40000000 loop 2 t 0x5000 x 0x70000 loop 3 t 0x1000 0x40000000 ret 0x0
rdcodec addr 0x7e ... loop 1 t 0x1000 x 0x40000000 loop 2 t 0x5000 x 0x70000 loop 3 t 0x1000 0x40000000 ret 0x0
pcm0: ac97 codec invalid or not present (id == 0)
device_probe_and_attach: pcm0 attach returned 6

And this is the relevant line from "pciconf -l":

none0@pci0:14:0:        class=0x040100 card=0xa0001458 chip=0x58801274 rev=0x03 hdr=0x00

I modified es137x.c, changing the test

  revid == 7 || revid >= 9 || (devid == ES1371_PCI_ID3 && revid == 2)

to (yes, I know it is ugly ;-) ):

  revid == 7 || revid >= 9 || (devid == ES1371_PCI_ID3 && (revid == 2 || revid == 3))

Now, the AC97 codec is correctly detected, and audio playing seems to
work (I cannot test audio recording because I have no microphone).
Perhaps this little patch could be applied and even MFC'ed before
4.3-RELEASE.

Cheers,
