• ThinkPad with Dolby Audio
After upgrading the operating system from Windows 10 (1803) to Windows 10 (1809), if the Dolby Audio cannot work, do the following:
1. Go to Control Panel and view by Category. Click Programs ->Programs and Features. Follow the on-screen instructions to uninstall Dolby Audio X2 Windows App.
2. Go back to Control Panel and click Hardware and Sound -> Device Manager. Expand Sound, video and game controllers. Right-click Conexant SmartAudio and select Uninstall device.
3. Select Delete the driver software for this device and follow the on-screen instructions to complete the uninstallation. Then restart the computer. Ensure that the audio driver has been uninstalled successfully.
4. Download and install the latest Conexant Audio driver from the Lenovo Support Web site.
とあったので、試してみる。
1のDolby Audio X2 Windows Appは普通に入ってたので削除
2のConexant SmartAudioが入ってなくて、うちではAudio Device on High Definition Audio Busだけど、一旦消してみる。インテルのディスプレイ用オーディオはHDMIのオーディオチャンネルだろうから削除しない。
