    sound devices not working after recent Windows Update


    I have a Windows 10 computer (an Intel NUC) with built-in sound (Realtek) and an external USB-driver D/A convertor (essentially a USB sound card).

    Some time after an update (although I'm not sure these incidents are related), my sound control panel now shows "no output devices found." So both the Realtek and my D/A convertor have disappeared.

    (Note: the D/A convertor uses an Audio Class 2 driver provided by XMOS.)

    The latest XMOS driver doesn't fix the problems with the D/A convertor. I haven't tried changing the Realtek Driver. I found a blog post that suggested a recent update pushed the wrong version of an Intel SST driver.

    I have version 9.21.0.4260 of the SST driver, which according to the blog post is NOT the problematic version.

    Troubleshooting my audio results in the message "plug in a sound device" which I presume means plug something into the headphone jack on the NUC. I tried this, and no change, neither sound device was present.

    Any suggestions at this point?

    Hi, perhaps you need an older driver.. example:
    Best Win 10 driver for C-Media 6206 LX based 5.1 USB sound card

    I seem to recall a similar thread a few months back..

    Could help if you provided full specs (under My computer - see mine for comparison), and details of the update you're referring to.
    Some time after an update
    - CU? Feature update (upgrade)?

    And of course your current Windows build.

    Thanks.

    Windows Update, operating system update, or whatever it's called. The thing that happens when it says "update and shut down" in the power button menu.

    Intel NUC 7i5BNH
    Windows 10 Home version 10.0.17763 (build 17763)
    8 GB system RAM
    128 GB SSD
    Intel i5-7620U CPU, 2.20 GHz, dual core

    any other specs you need?

    I'm not sure what you're referring to when you say "see mine".

    Oh I forgot to say that I tried rolling back the SST driver. Didn't help. The Realtek driver, when updating, says "you already have the best version" and rollback isn't available.

    Here's an article that looks promising. I haven't tried rolling back the cumulative update yet. (I didn't know what CU was in your post until I read this article - I presume you mean cumulative update?)

    Please post a screenshot of your Update History to show to which update you may be referring.
    To post a screenshot please use the Insert Image icon above your post.

    an external USB-driver D/A convertor
    What model is this?

    In the example thread I quoted a driver delivered for Win 8 was needed. That's different to rolling back a driver. I'm not saying that's necessarily the solution in your case, of course..
