    ok, i have a massive issue with my audio equipment:
    my USB soundcard (m-audio connectiv), which used to work fine, now causes my macbook to get glitchy and freeze, also the audio gradually builds up static until the music it completely inaudible. as you can imagine this is hugely frustrating as i depend on this equipment for production and DJing, so i would be desperately happy if someone helped me fix this.

    This occurs on both USB ports

    This occurs with airport and bluetooth switched on or off

    It happens with any audio from any application

    My laptop was running OSX10.5.5 when this occurred, since which have tried downgrading to 10.5.1... no difference.

    I've uninstalled/reinstalled/updated/downgraded drivers for the soundcard... no difference.

    The soundcard its self is working fine, i've tested it on my desktop computer which runs OSX10.5.5

    Same with the usb cable, so its not that.

    its not an issue of underpowering from the USB port as i have tried it with an independent power source, with no result.

    I've run the Apple Hardware Test, which reported no problems. all accounts everything is functioning perfectly, i cannot understand why these problems are occurring.
