    I'm running 5.3-Release amd64 on an Asus AV8 motherboard which includes
    Realtek ALC850 audio chipset. I'm unable to get the system to recognize
    the chipset. From the archives/man pages/manual I've :

    # kldload snd_driver
    kldload: can't load snd_driver: No such file or directory

    Modified /boot/loader.conf to use :

    sound_load="YES"
    snd_driver_load="YES"

    Recompiled the kernel with :

    device sound

    The last one resulted in /dev/sndstat showing up, but the contents show
    no devices :

    # cat /dev/sndstat
    FreeBSD Audio Driver (newpcm)
    Installed devices:

    However I don't see any snd_* modules in /boot/kernel/*ko

    I also noted that sys/dev/sound/pcm/ac97.c contains the following :

    static const struct ac97_vendorid ac97vendorid[] = {
            { 0x414c4300, "Realtek" },

    static struct ac97_codecid ac97codecid[] = {
            { 0x414c4790, 0x0f, 0, "ALC850", 0 },

    At this point I'm at a loss as to where to go from here, or which kernel
    module would support this chipset.

    Other than that this system is a screamer. This is my first experience
    with 5.3, AMD, and with the 64 bit port, so far I'm really impressed. I
    saw reports that the Marvell Gig Ethernet wasn't working for some folks,
    but it worked fine for me. I chose this motherboard as it was the only one
    of about three that supported socket 939 and had the Via K8T800 chipset, I
    was concerned about the reports of problems with the nVidia nForce
    chipset. I would have liked to have had PCI-X, but that's only available
    today with nVidia. The Promise SATA raid controller (one of two different
    brand controllers onboard) worked just fine.
