Audio problem with latest 8.3 alpha on DisplayLink

[i2000s]

Using a Thinkpad USB 3.0 dock with the latest DisplayLink 8.3 alpha installed on WIndows 10 (Creator Update), but the audio output is just noise. No sound other than noise is putting out. What can I do?

See the log attached.

Hello and thank you for the logs.

You are using the 8.3 Alpha video driver. However you are still running the same audio driver as before on 8.2, as it wasn't changed or re-signed yet. You can see from device manager that the audio being ran is 8.2.1638.0.

Would you please install back 8.2 M2 and confirm the issue disappears?

Kind regards,
Alban

Hi Alban,

I'm sorry, I haven't got a chance to reinstall the 8.2 driver as I have to solve a significant slow down of computer for no reason recently. May I ask, do you mean the 8.3 Alpha video driver doesn't come with a compatible Audio driver in the package? I would prefer to use the 8.3 Alpha version as it has the fix to night-light mode.

Thanks!

Hello,

I am saying we have not changed the audio driver.

I'm asking if you could check again with 8.2 to see if the issue disappears.
If so, then there is a regression. If it stays an issue, then the fact that it started when you installed 8.3 is a coincidence.
You can then re-install 8.3 Alpha to benefit from the colour correction feature.

Kind regards,
Alban

I have used the DisplayLink Cleaner to uninstalled the 8.3 Alpha driver, restarted and then installed the 8.2 M3 driver downloaded on the DisplayLink website. Now, the audio seems working fine by playing a few YouTube videos online.

I noticed that the Audio driver is actually signed by Microsoft with version number 10.0.15063.447. Is this normal? What should I do next?

Thank you for your prompt response!

Hello,
The audio driver you are using is the brand new Windows inbox one.
Which we haven't yet switched to because it causes major *video* performance impact on that version. We have worked with Microsoft on making an inbox driver we can use, to lighten our driver even more.
We intend to switch to the inbox audio driver when it is fixed. It's supposed to be fixed recently but we haven't yet verified it so this would be in our v8.4.

Could you please force the DisplayLink audio driver by:

1. Go to Device Manager
2. Edit the properties of the audio device
3. Select Update driver
4. Then select Browse my computer
5. Let me pick...
6. Have Disk...
7. Navigate to C:\Program Files\DisplayLink Core Software\Drivers
8. Select dlusbaudio.inf
9. It will show "DisplayLink USB Audio Adapter"
10. Click on Next
11. It shows "installing drivers..."
12. Confirm the driver version is now DisplayLink 8.2...

Kind regards,
Alban
