Saya memiliki Dell Inspiron 15 7537.
Saya telah menginstal 14,04 di atasnya, dan tidak punya masalah dengan suara pada awalnya. Namun, seperti kartu ethernet saya, sepertinya berharap tidak memiliki masalah driver / software di linux tidak realistis.
Saya membeli SSD untuk laptop dan menginstal Ubuntu 14,04 pada itu. Kemudian, saya menggunakan gparted untuk menyalin partisi windows dari disk yang disertakan dengan laptop.
Semuanya masih berfungsi dengan baik, sampai saya boot ke Windows 8.1. Suara bekerja dengan baik ketika saya masih di Windows, tetapi setelah me-reboot laptop, dan kembali ke Ubuntu, suara berhenti bekerja melalui speaker laptop internal.
Namun saya perhatikan, saya masih bisa menggunakan headphone untuk menerima suara saat di Ubuntu.
Dari sini, saya bisa boot ke Windows 8.1 untuk menerima suara melalui speaker internal, tetapi saya tidak bisa lagi membuat suara bekerja lagi di Ubuntu 14.04 kecuali menggunakan headphone.
Saya memutuskan untuk bereksperimen, jadi saya benar-benar menghapus disk, dan melakukan instalasi baru Ubuntu 14.04. Suara itu kembali! Saya kemudian kembali menyalin partisi windows saya. Sekali lagi, setelah boot ke Windows 8.1, dan kemudian kembali ke Ubuntu, speaker internal saya tidak lagi menghasilkan suara.
Saya telah mencoba solusi yang paling umum seperti:
sudo apt-get remove --purge alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio unity-control-center
sudo alsa force-reload
atau
pulseaudio -k
Saya juga telah mencoba memastikan bahwa tidak ada yang dibisukan dalam alsamixer. Saya juga telah mencoba menginstal alat kontrol volume audio pulsa. Jika saya memainkan lagu, saya dapat melihat level audio bergerak untuk speaker internal, seolah-olah itu harus diputar.
Alat kontrol volume audio pulsa juga menunjukkan kartu HDMI saya adalah perangkat suara, tetapi kartu itu mengakuinya mati.
Mungkin perlu dicatat bahwa dalam alsamixer, aplikasi ini tampaknya mengenali kartu PCH / output saya sebagai kartu sekunder, dan HDMI sebagai yang pertama. Namun, ini selalu terjadi, jadi saya tidak yakin itu masalahnya.
Saya tidak tahu banyak tentang bagaimana ini semua direkayasa, tetapi dalam pemahaman saya, saya mengalami kesulitan mengumpulkan bagaimana mem-boot ke OS lain dapat menghentikan speaker dari bekerja di yang lain.
Apa yang bisa saya lakukan untuk mengembalikan suara ke sistem saya, dan menentukan mengapa boot ke windows menyebabkan perilaku ini? Saya sangat ingin menggunakan sistem dual boot.
