O arquivo foi criado executando:
alsamixer alsactl --file ~/.config/asound.state store Depois do meu .bashrc eu coloquei:
alsactl --file ~/.config/asound.state restore
Mas essas configurações, apesar de me proporcionarem uma reprodução no áudio do painel frontal e no áudio do painel traseiro, soam como um lixo. Até mesmo toca algumas freqüências quando, ao longo de um vídeo, alguém fala de alguma forma que a qualidade do som é baixa.
Minhas interfaces de áudio são (fornecidas pelo comando lspci | grep Audio ):
00:1f.3 Audio device: Intel Corporation Sunrise Point-H HD Audio (rev 31)
01:00.1 Audio device: NVIDIA Corporation GF119 HDMI Audio Controller (rev a1)
Instale pavucontroll via apt :
sudo apt install pavucontroll
Em seguida, inicie-o via traço e, quando for iniciado, selecione o Output Devices ( Συσκευές Σξόδου in Greek;)):
Emseguida,selecioneondeestáescritoheadphonescomovocêvênaimagem(MyUiestáemgregoesuponhoquevocêuseanalogstereoduplex):
Em seguida, selecione o canal de cadeado e MUTE o canal front right . Pressione o cadeado novamente e você está pronto.
