應該說我什麼都沒動過就突然沒有音效，所以應該不是防毒軟體之類的問題?

你好，我無法復現你說的問題。首先當然要確認已經勾選了“語音”複選框（在貓娘已經出現在熒幕中之後，反復點擊數次，最後停留在勾選狀態）。
然後請注意看點擊互動（點擊頭部）時貓娘是否有張嘴。若有，則拖動角色面板中的音量滑動條到最右側，再互動看是否有聲音。
若問題沒有解決，請更詳細地描述。

就是真的完全什麼都沒有動結果就突然沒有音效
不知道這跟我之前休眠了一小段時間有沒有關系
精準地說是我休眠前沒問題
然後打開電腦後點擊就沒聲音了

那就請重新啟動電腦再試一下呢。

有重啟過了，也重新下載過了(程式跟這個桌布)，可是還是沒有聲音

請你描述按照2樓操作的結果：
有沒有在貓娘顯示之後重新勾選“語音”複選框？
貓娘在互動時是否有開口？
有沒有將音量滑動條拉至最大？

有沒有在貓娘顯示之後重新勾選“語音”複選框？

有

貓娘在互動時是否有開口？

有

有沒有將音量滑動條拉至最大？

有

我確定我完全沒有碰關於音量的事物
we也不是靜音

右鍵點擊Windows任務欄的音量圖標——打開音量混合器，看看有沒有將桌布程式設置為低音或是靜音。

沒有，確定過了

我認為桌布這邊應該是沒有問題的。你可以通過電子郵箱向我提供日誌文件（首先打開桌布，隨便互動幾下，然後關閉桌布。隨後將日誌文件找到發送給我，提供日誌的方法請參照“常見問題解答”第2條），我會看看內部有無問題。
除此之外我目前沒有什麼可以幫到你了。

哦，還有一條請嘗試，那就是刪除存檔。
首先關閉桌布程式。
存檔位於 C:\Users\用戶名\AppData\LocalLow\Project-AZUSA\NekoWallpaper目錄下（跟日誌文件在同一位置），把除了txt、cfg以及文件夾之外的文件（也就是沒有後綴名的文件）全部刪掉。
然後重新打開桌布程式（此時聲音複選框可能會重置，重新勾選）再測試。

C:\Users\用戶名\AppData\LocalLow\Project-AZUSA\NekoWallpaper目錄下
可是我在我的user裡沒有找到這個資料夾

沒有LocalLow (大多是Local)
然後可以問一下你的郵件嗎?

後來找到了把Main-0 跟save 刪了重開
還是一樣

我的郵件在此桌布的首頁（描述頁面）是有寫的，應當無需再問。
不過日誌文件很明確地已經指出了你系統存在的問題，就是這一行：

FMOD failed to initialize. This may be because your sound card is configured to give applications exclusive access, thus preventing Unity from using this device. You can change this in Control Panel > Audio Devices and Sound Themes > Playback Device > Properties > Options ... : "Soundcard does not support the minimum features needed for this soundsystem (16bit stereo output).
