Update 11/4/2015 – At this time there is still no resolution for this issue and there has been some confusion about what audio is affected. The only audio that does not function after upgrading to Windows 10 is the audio output jack on the front of the Pro8 dock. The attached tablet’s built in speakers and headphone/speaker jack will work fine.
After updating to newly-released Windows 10, several customers have contacted us saying the audio in their Pro8 docking stations stopped working. Testing has shown that this happens only in 32-bit versions of Windows 10, not 64-bit. However, the majority of the tablets compatible with the UD-PRO8 are using 32-bit Windows and will experience this issue after the upgrade.
The malfunction appears to be related to a glitch in the driver installation process, and will prevent audio output when the “USB Multimedia Audio Device” is selected. If you are using a Plugable UD-PRO8 with 32-bit Windows 8.1, we recommend delaying the Windows 10 update until a fix has been found. However, if you have already upgraded to Windows 10 or don’t want to wait, there is a work-around.
Installing the following drivers will temporarily restore audio function, however, they must be manually reinstalled each time Windows 10 is restarted:
Restart Windows after installing the drivers and be sure to set “USB Multimedia Audio Device” again as the default audio device.
Restarting the computer after that is a two-step process:
1. Run the installer above before restarting, and allow it to remove the drivers.
2. Restart the computer, reinstall the driver, then restart again.
We will update this post once a more permanent solution is found.
