Eu tive um problema antes, no qual o Ubuntu não detectou meus fones de ouvido, o que ainda não foi corrigido.
O problema agora é que quando eu digito alsamixer no terminal eu recebo cannot open mixer: No such file or directory e quando eu digito aplay -l eu recebo aplay: device_list:268: no soundcards found... .
O Ubuntu encontra minha placa de som quando eu digito lspci -v | grep -i audio , ela retorna a seguir:
00:1b.0 Audio device: Intel Corporation 8 Series/C220 Series Chipset High Definition Audio Controller (rev 05)
Subsystem: ASUSTeK Computer Inc. 8 Series/C220 Series Chipset High Definition Audio Controller
01:00.1 Audio device: NVIDIA Corporation GM204 High Definition Audio Controller (rev a1)
Subsystem: NVIDIA Corporation GM204 High Definition Audio Controller
Também cat /proc/asound/cards dá cat: /proc/asound/cards: No such file or directory
Eu tentei reinstalar alsa-base, alsa-utils e linux-sound-base, e também tentei
sudo aptitude --purge reinstall linux-sound-base alsa-base alsa-utils linux-image-'uname -r' linux-ubuntu-modules-'uname -r' libasound2
sem sucesso.
As configurações de som mostram uma "saída fictícia" como alto-falante.
sudo lspci -vnn | awk -vRS= '/Audio device/'
Gera isso:
