Saya menggunakan ubuntu 13.10 64bit. Saya mendapatkan suara satu sisi (satu saluran) hanya di headphone. Speaker laptop cukup bagus. Headphone jack laptop dan headphone keduanya bekerja dengan baik. Ini masalah perangkat lunak. Saya secara teratur memperbarui sistem dan masalah ini terjadi setelah peningkatan 1 atau 2 terakhir.
Juga ada solusinya. Atur level volume ke rendah dan atur tinggi dengan cepat. Setelah melakukan ini beberapa kali mengembalikan kedua saluran headphone saya. Bagaimana cara mengatasinya secara permanen?

Apakah Anda juga memeriksa headphone di perangkat yang berbeda?

Solusi Anda (Atur level volume ke rendah dan setel dengan cepat. Setelah melakukan ini beberapa kali, kembalikan kedua saluran headphone saya.) Berfungsi untuk saya. Bagaimana Anda bisa mengatasinya? ada mengapa itu memperbaikinya?
