    HDMI cable kills sound, no picture on monitor

    Phooey. The external ports on the Thrive never fail to disappoint. I just went out and bought what seems like a very high-quality DigiLINK HDMI-DVI cable in order to export video from my (still!) Honeycomb 3.2.1 tablet to a ThinkVision 9419-HB7 monitor. Not only is there no picture on the monitor, but plugging in the cable also kills the sound in the tablet. Suggestions? Thanks.

    Plugging in the cable is supposed to kill the sound on the tablet, or dock, if you use one.
    Both video and audio are routed through the HDMI.
    That's by design.
    No idea on the other issue - don't have a TV that accepts HDMI.

    How odd. The package the cable came in reads: "19-pin Male (Type A) <--> 24+1 pins Male, 24AWG This cable transfers 'VIDEO' only between DVI-D single-link and HDMI devices..." and the monitor has no speakers.

    Then it might not be a standard HDMI cable.
    This is the standard:

    Audio and video are both carried.

    It doesn't matter if your external device has sound, if hdmi is plugged in sound is routed out the digital channel, no way around it, at least not without some modding to audio routing. That portion we can actually work around.

    Dvi lacks a very important part of using an hdmi cable, and your monitor also does, but the digital handshake the thrive is waiting for never happens, your setup simply will not work, the hardware and method you chose aren't compatible with the thrive. Its not a fault of the thrive, or even a flaw, its not meant to do what you want it to do in the manner you want to do it in.

    The cable fits the connectors correctly. Is there anything non-standard about the description? Then, assuming I get the picture on the monitor working, is there a way to re-activate the sound on the tablet speakers? The ThinkVision monitor has no speakers. Is the audio-out (earphone) jack on the Thrive still supposed to work?

    I think that Pio covered it. :beer:
    The circuitry recognizes the cable being plugged in, so sound is routed through whether it can be utilized at the other end or not.
    Probably not any easy way around it given only the equipment at hand.
    You can try it, as you have the items there, but I believe the headphone jack would be shut off as well.
    Same reason.

    Its not the cable not working, its working fine I'm sure, but the monitor will NOT send the security handshake over the Dvi, the thrive will NOT output video until this handshake is done. Dvi doesn't usually carry this signal anyways, but I think its more depending on the monitor itself. Using it on a tv would probably work as its using hdmi>hdmi and it knows to follow the handshake protocol for hdmi use.

    As I said audio routes to digital, it won't (normally) put audio out anywhere besides digital, which is hdmi.

    In short, this won't work.

    EDIT: if its rooted I think we can trick the audio routing, but still pointless if video isn't working.

    OK, thanks for the prompt info. I will take it back to the store, and this will offset the cost of the parking ticket I picked up picking it up. Some things just don't work out...

    A monitor with an hdmi port may work better for this setup, if you go that route we can get audio routing hacked for you :beer:
