    Windows 8 not seeing USB sound card after wake from sleep


    Hi. I have a home built HTPC running Windows 8 with Windows Media Center. My sound card is a Silverstone EB01 USB DAC (i.e., it's an external USB device). When the computer wakes from sleep, there is no sound. I can fix this by either (a) unplugging and reconnecting the USB connector or (b) disabling then re-enabling the sound device.

    This is driving me and my family crazy. What's worse, it worked perfectly fine under Windows 7.

    There are no drivers for this device, it's pure plug'n'play. In case it's relevant, the Device Manager seems to recognise it as a Burr-Brown PCM2072E.

    I would be extremely grateful if anyone could help me fix this one.

    If it is in device manager, check it's properties and power savings for it. In power settings plan could be some settings for it to.

    I'm afraid this is just a plain old USB device; there are no power settings for it.

    Hi, yes I can confirm there is no power management tab for this device.

    I'm starting to wonder whether this could be something to do with the particular USB port, but I'm doubtful: the device has its own power supply.

    As I say, this whole thing is odd. From right-clicking the loudspeaker icon on the dock I can see the device, disable, then re-enable it, and that fixes the problem. Most odd.
