I decided to post a quick guide for Xonar STX (CMI8788), Xonar ST (according to driver description support): "A tiny bit modified xonar-freebsd driver adapted for DragonFlyBSD. Also supports Asus Essence ST card.
Original author: Alexander Polakov"

  1. clone/download the driver from git:

    $ git clone
  2. make module snd_xonar[/B]
    $ make && make install
  3. add/edit to /etc/rc.conf
  4. load the module
    # kldload snd_xonar
  5. check snd devices and make STX/ST default
    $ cat /dev/sndstat
    Installed devices:
    pcm0: <Asus Xonar Essence STX (AV100)> (play)
    pcm1: <ATI R6xx (HDMI)> (play)
    $ sysctl hw.snd.default_unit=0
  6. reboot or restart volume mixer and pump up a volume to 80%
PS works with mine STX

Somebody adapted this or being able to adapt this for other versions already?

static const struct {
    uint16_t vendor;
    uint16_t devid;
    char *desc;
} xonar_hw[] = {
    /* we actually support only this one, it shouldn't be too hard to add others */
    { ASUS_VENDOR_ID, SUBID_XONAR_STX, "Asus Xonar Essence STX (AV100)"     },
    { ASUS_VENDOR_ID, SUBID_XONAR_ST,  "Asus Xonar Essence ST (AV100)"     },
#if 0
    { ASUS_VENDOR_ID, SUBID_XONAR_D1,  "Asus Xonar D1 (AV100)"         },
    { ASUS_VENDOR_ID, SUBID_XONAR_DX,  "Asus Xonar DX (AV100)"         },
    { ASUS_VENDOR_ID, SUBID_XONAR_D2,  "Asus Xonar D2 (AV200)"         },
    { ASUS_VENDOR_ID, SUBID_XONAR_D2X, "Asus Xonar D2X (AV200)"         },
    { ASUS_VENDOR_ID, SUBID_XONAR_DS,  "Asus Xonar DS (AV66)"         },
Would love to hear my DX card with OSS, but has other DACs inside (CS4398 (front) and the CS4362A (centre, side and rear)).
