現在、私はhololens2とholographic remoting playerとunityを用いて開発を行っています。以下の画像のようにメインカメラに対してaudio listenerとaudio sourceを付与し、音を流そうとしています。しかし、実際には音声はpc側のスピーカーから流れてしまいます。これをhololens2側から流すためにはどのような手順を踏めばよいのでしょうか。また、pc側のスピーカー設定ではhololens2を選択できません。 hololens sound setting bug

I'm sorry. My mistake, I put the text before translation. I will send you the same sentence translated into English.

I am currently developing using hololens2, holographic remoting player and unity. As shown in the image below, I have given audio listener and audio source to the main camera and am trying to play sound. However, the audio is actually played from the speakers on the PC side. What steps do I need to take in order to play it from the hololens2 side? Also, I cannot select hololens2 in the speaker settings on the pc side.

Hello, Welcome to Microsoft Q&A,

Have you tried checking Enable Audio in Holographic Remoting for Play Mode? Please refer to the picture below to check.

I set emulate mode to remote to device and enable audio, but this causes a connection error. After repeating this many times, the unity file crashed. When the emulate mode is set to none, the connection is established without any problem.

What version of Unity are you using? For developing for HoloLens 2, our recommendation is to develop with Unity 2021.3 LTS + OpenXR. Please refer to Choosing a Unity version and XR plugin - Mixed Reality | Microsoft Learn.

I'm using version 2020.3LTS of unity. The task has a deadline and we do not want to change the version in the future.

The "Open XR Plugin" from the Mixed Reality Feature Tool is used. Is it different from this?

Judging from the screenshot you provided earlier, you should be using the Windows XR Plugin. For Unity 2020.3 LTS, it supports both OpenXR and Windows XR plugin, but we recommend using OpenXR. You can refer to Set up a new OpenXR project with MRTK - Mixed Reality | Microsoft Learn to check if OpenXR is configured correctly.

If you are using OpenXR, then you should be able to use the Holographic remoting for play mode, please refer to Preview and debug your app with Holographic Remoting for Play mode - Mixed Reality | Microsoft Learn.

Thanks for answering, I will change to OPEN XR and give it a try. If I don't understand, I will ask again.
