    I'm running FreeBsd/amd64 on a Gateway 7422GX. I installed the
    5.3-release version and configured the OS to function properly with
    the hardware except for the built-in wireless and the infamous
    conexant softmodem. I read up on some wireless setups to get my
    wireless card working. In the process, I decided to try my first
    attempt at a rebuild of world with the latest cvsup stable-supfile
    download (March 24, 2005). I used the method of:

    # make buildworld
    # make buildkernel KERNCONF=MYKERNEL
    # make installkernel KERNCONF=MYKERNEL
    # reboot

    selected singleuser mode from startup menu

    # fsck -p
    # mount -u /
    # mount -a -t ufs
    # swapon -a
    # mergemaster -p
    # make installworld
    # mergemaster
    # reboot

    (MYKERNEL is the GENERIC plus the lines needed for loading the sound
    system and the via8233 sound driver for my sound card)
      device sound
      device "snd_via8233"
    (with mergemaster I chose "i" for each file, indicating to use tempory)

    I booted into the new environment and started KDE3.4. I noticed that
    I had no sound and no usb mouse functionality. I did the following:

    # cat /dev/sndstat
    FreeBSD Audio Driver (newpcm)
    Installed devices:
    pcm0: <VIA VT8235> at io 0x1000 irq 10 (5p/1r/0v channels duplex default)

     So, the driver seems to be loading, but I'm getting no sound. I've,
    also, done the following to try to get the sound back.

    # sysctl hw.snd.pcm0.vchans=8
    # sysctl hw.snd.maxautovchans=8

    I checked my mixer levels in KDE and added

    hint.pcm.0.vol="100"

    to the /boot/device.hints

    being that the usb mouse also stopped working, I think there might be
    an issue with the hardware discovery routines in bootup or a
    configuration file that 5.3 used was overwritten with the rebuilding
    of world.

    I'm quite new to FreeBSD and am trying to get a good grasp on the
    general workings of the OS. So, assume that I need step by step
    guidelines. Perhaps, since I'm dealing with a pre-release, some of
    the functionality is missing by design. I have assumed that STABLE
    would mean that functioning hardware from the prior release will
    continue functioning with STABLE. I've stayed clear of CURRENT
    assuming things may often be broken in that branch, as it is
    experimental.

    Any help in enlightening me on my hardware issues will be greatly appreciated.
