Tôi chưa quen với Linux nhưng thực sự yêu thích Tiểu học vì sự đơn giản của nó. Sau khi nhận thấy rằng âm thanh của tôi khá kém ở Tiểu học, so với Windows 8.1, tôi đã thử cập nhật trình điều khiển âm thanh. Tôi đã kết thúc việc tải xuống một từ đây nhưng sau khi khởi động lại, biểu tượng âm thanh của tôi đã biến mất khỏi thanh công cụ và không nghe thấy âm thanh nào. Trong cài đặt & gt; âm thanh tôi thấy "Đầu ra giả" và đang chạy alsamixer nói cannot open mixer: No such file or directory. Tôi đã Googled xung quanh mà không có bất kỳ thành công và nhiều đề nghị sudo alsa force-reload nhưng điều đó trở lại
Unloading ALSA sound driver modules: (none loaded).
Loading ALSA sound driver modules: (none to reload).
Tôi đã mất hy vọng và tôi hy vọng ai đó ở đây có thể giúp đỡ. Tôi đã gỡ cài đặt trình điều khiển mà tôi đã tải xuống trước đó từ liên kết ở trên (có thể có những phần bị bỏ lại?) Và đã cài đặt lại cả alsa-base và pulseaudio nhưng tôi vẫn không thể thấy biểu tượng âm thanh hoặc phát âm thanh.
Bất kỳ trợ giúp nào cũng được đánh giá rất cao.
