[已解決]Windows10 系統下HDMI 顯示器 沒有聲音輸出的奇怪問題

今天想用一下顯示器內建的喇叭，忽然發現聲音輸出選項裡HDMI的聲音裝置沒了。之前開始使用這台顯示器的時是用過一段時間的。

百度了一番，沒發現什麼線索。後來去Google找到這麼一段文字：

I‘m not sure where to report this, but after I upgraded a Lenovo Y50 laptop to Win 10 64 Enterprise, the HDMI audio stopped working.

 

All the drivers were installed, and the correct options were selected in the audio panel.

After much research I stumbled upon a post on a message board which had a suggestion that didn‘t make any sense, but I tried it anyway, and it resolved the issue.

 

The suggestion was to uninstall Hyper-V.

Once the Hyper-V feature was uninstalled from Windows, HDMI audio started working again.

 

It seems that for whatever reason, Hyper-V is interfering with HDMI audio out in Windows 10.

This problem did not exist in 8.1

 

Can you guys look into this?

 

隨便瀏覽一下，大概是跟Hyper-V有關係。我查看了一下，Hyper-V之前，因為一個什麼原因，被我暫時卸載停用了。（記得當時HDMI有輸出聲音的時候，是有Hyper-V在的）

於是，重新把Hyper-V啟用，重啟電腦後，HDMI的聲音輸出裝置又回來了。

 

貌似，我的情況跟上面搜尋到的情況相反。但都是跟Hyper-V的啟用和禁用有關係。

 

電腦配置：Dell XPS 15z,

作業系統：Windows10 專業版，英文版本

顯示器： LG-29UC97C
