音频问题:显示“虚拟输出”,但我听不到任何声音

音频问题:显示“虚拟输出”,但我听不到任何声音

音频仅适用于蓝牙设备,即使我连接了辅助设备,也无法识别。我尝试打开,alsamixer 但它显示

ALSA lib confmisc.c:855:(parse_card) cannot find card '0'
ALSA lib conf.c:5178:(_snd_config_evaluate) function snd_func_card_inum returned error: File o directory non esistente
ALSA lib confmisc.c:422:(snd_func_concat) error evaluating strings
ALSA lib conf.c:5178:(_snd_config_evaluate) function snd_func_concat returned error: File o directory non esistente
ALSA lib confmisc.c:1334:(snd_func_refer) error evaluating name
ALSA lib conf.c:5178:(_snd_config_evaluate) function snd_func_refer returned error: File o directory non esistente
ALSA lib conf.c:5701:(snd_config_expand) Evaluate error: File o directory non esistente
ALSA lib control.c:1528:(snd_ctl_open_noupdate) Invalid CTL default
impossibile aprire il mixer: File o directory non esistente

所以我无法修改任何东西。cat /proc/asound/cards这样做会说no soundcard ,但是如果我运行lspci | grep -i audio,它会说:

0000:00:1f.3 Multimedia audio controller: Intel Corporation Tiger Lake-LP Smart Sound Technology Audio Controller (rev 20)

运行此aplay /usr/share/sounds/alsa/Front_Center.wav 程序时终端显示正在播放但我听不到任何声音(只有重复连接到蓝牙设备的过程才能听到)如果我运行pulseaudio,它会说:

E: [pulseaudio] pid.c: Daemon already running.
E: [pulseaudio] main.c: pa_pid_file_create() non riuscita.

我无法在设置中切换设备,因为唯一可用的输出是“虚拟输出”

我解决了!

我已经做好了

sudo apt remove --purge alsa-base pulseaudio

然后我再次安装

sudo apt install alsa-base pulseaudio linux-sound-base 

sudo apt install ubuntu-desktop-minimal
