Sejak 6 jam saya mencari di web dan mencoba untuk mendapatkan headphone USB Bowers & Wilkins PX, yang berfungsi dengan baik sebelum beberapa pembaruan, untuk bekerja - tanpa hasil.

Apakah Anda menginstal driver? Apakah mereka menyatakan bahwa mereka kompatibel dengan OS Anda?

Tidak ada driver yang tersedia dan tidak diperlukan. Seperti yang saya tulis, beberapa waktu lalu semuanya bekerja dengan baik. Saya hanya perlu sudo alsa paksa-reload.

Mengapa memilih? Berapa hari Anda perlu menunjukkan upaya, apa yang tidak jelas dan menyenangkan bahkan jika itu tidak penting bagi pemilih, bagi saya itu sangat, sangat penting untuk menjalankan headphone ini!

snd-usb-audioadalah driver untuk antarmuka standar, kecuali headphone memerlukan kekhasan, itu harus kehabisan kotak. Hal-hal yang bisa salah adalah (1) perubahan dalam driver kernel, atau kekhasan baru yang tidak berfungsi untuk model Anda (apakah Anda meng-upgrade kernel Anda? Dari versi ke versi mana?), Atau (2) masalah perangkat keras dari berbagai jenis (akan sulit untuk di-debug).
Terima kasih banyak, terima kasih! Kamu benar. Sementara itu saya menemukan itu adalah bug kernel . Sayangnya versi perbaikan bug tidak kompatibel dengan driver NVIDIA. Jadi saya harus memeriksa apakah saya dapat menambal kernel saya.
