Pulseaudio
Debian 10 上的麥克風問題
我正在嘗試與安裝在 macbook pro 上的 debian 10 建立不和諧聊天。不和諧中列出了兩個輸入設備。預設和內置音頻模擬立體聲。我使用的是預設值，它執行良好。當我關閉電腦並在第二天重新啟動時，discord 說它無法檢測到來自我的麥克風的任何輸入。我只想使用我的內置筆記型電腦麥克風。
alsamixer: : 我應該改變什麼？
sudo alsamixer
編輯：另外：為什麼“麥克風”級別是空的？
只是做了一個
sudo alsactl init然後將我的音量改回我想要的方式，這一切都奏效了。
首先我試過：
felipe@SDF-1:~$ apulse felipe@SDF-1:~$ sudo apt-get install tetraproc Reading package lists... Done Building dependency tree Reading state information... Done The following additional packages will be installed: libclthreads2 libclxclient3 The following NEW packages will be installed: libclthreads2 libclxclient3 tetraproc 0 upgraded, 3 newly installed, 0 to remove and 0 not upgraded. Need to get 111 kB of archives. After this operation, 390 kB of additional disk space will be used. Do you want to continue? [Y/n]`I installed the whole Alsa它沒有用。
然後，我嘗試了：

然後，
felipe@SDF-1:~$ felipe@SDF-1:~$ sudo alsactl init Found hardware: "HDA-Intel" "Conexant CX20549 (Venice)" "HDA:14f15045,103c30cd,00100100" "0x103c" "0x30cd" Hardware is initialized using a generic method felipe@SDF-1:~$ alsamixer felipe@SDF-1:~$ felipe@SDF-1:~$ felipe@SDF-1:~$ felipe@SDF-1:~$ sudo apt autoremove Reading package lists...
