    Inside the xoom speaker dock

    i wondered if it was possible to mod the speaker dock so that it could have a USB socket on the back
    what confused me when taking it to bits is that there are 5 cables + screen/earth
    so if 2 are used for power and 2 for data that leaves at the most 2 for audio and for stereo you would usually need 3
    so is the audio being delivered to the dock as a data stream ?
    see attached pic's
    interesting to note that the speakers are side mounted

    It looks pretty much like the circuitry in the standard dock in that the sound system is controlled from a generic USB sound card. The difference here is that istead of a 3.5mm socket there is a small digital amplifier connected to speakers.

    Essentially if you want to have a USB passthrough as in the standard dock mod, then you will lose the the sound features of the dock. I think it would be cheaper to modifiy a standard dock. I have toyed with the idea of using a hub that could be built inside but the problem is finding a hub capable of passing a data signal from a PC via the OTG connection. The other option would be to wire in a mechanical switch to toggle between the sound circuitry and an external USB connection. Of course a 6pole 2throw switch takes up a lot of space!

    The more I think about it a 4PDT switch could do the job but once again the location could be an issue... I have a spare standard dock. Time to experiment!

    Welcome to the forum, glad you decided to join us. There are a couple of threads on modding the speaker dock, If I can find them again I'll post them later.
