Ini sepertinya menjadi masalah dengan pulseaudio. Saya login melalui VNC di ponsel saya dan mulai memutar video yang menyebabkan X mogok (seperti yang kadang-kadang terjadi). Saya memulai kembali dan tiba-tiba suaranya tidak bekerja.
Saya memiliki Intel HDA / Realtek ALC889
00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller
alsamixer
mendeteksi ini baik-baik saja.- PulseAudio tidak mendeteksi perangkat alsa ini sehingga digunakan
auto_null
sebagai bak cuci default (log di bawah). - Ketika saya benar-benar membunuh PulseAudio (katakan untuk tidak memulai otomatis) komunikasi ALSA langsung dengan kartu suara berfungsi dengan baik.
speaker-test
, misalnya, berfungsi. Jadi perangkat keras dan lapisan ALSA IMO baik-baik saja. - Dalam log, tampaknya kartu itu mungkin "sibuk" tetapi saya benar-benar tidak tahu bagaimana atau mengapa sekarang (dan tidak pernah sebelumnya). Apakah ada file kunci ALSA di suatu tempat yang masih ada karena kecelakaan saya?
Saya hanya berlari
sudo fuser /dev/snd/*
dan melihat ini:oli@bert:~$ sudo fuser /dev/snd/* /dev/snd/controlC0: 1884 /dev/snd/pcmC0D0c: 1884m /dev/snd/timer: 1884
Melihat daftar proses (
ps aux | grep 1884
) memberitahu saya proses 1884 adalaharecord -c 1 -f S16_LE -r 8000 -t raw
. Tidak tahu apa ini atau mengapa ini berjalan.Ketika saya mencoba dan membunuh
arecord
(sebagai root), itu hanya respawn dan rebind pada perangkat keras.
Saya berada dalam situasi yang sangat menjengkelkan di mana saya tidak tahu apa yang sedang terjadi dan tidak tahu bagaimana mengetahuinya. Saya terbuka untuk semua saran agar ini berfungsi lagi. Menembakkan.
Dan inilah yang saya dapatkan ketika saya menghentikan pengisian otomatis PA, bunuh dan mulai dengan -vvvv
.
oli@bert:~$ pulseaudio -vvvvv

melakukannya dan reboot untuk keberuntungan. Ternyata aku tidak beruntung hari ini :(
