Question

我最近在我的Raspberry Pi 3上安装了Jasper，但在运行时会遇到一系列ALSA错误。因此，我尝试了简单地运行扬声器测试，但收到了同样的错误。

speaker-test 1.0.28

Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise
ALSA lib confmisc.c:768:(parse_card) cannot find card '1'
ALSA lib conf.c:4259:(_snd_config_evaluate) function snd_func_card_driver returned error: No such file or directory
ALSA lib confmisc.c:392:(snd_func_concat) error evaluating strings
ALSA lib conf.c:4259:(_snd_config_evaluate) function snd_func_concat returned error: No such file or directory
ALSA lib confmisc.c:1251:(snd_func_refer) error evaluating name
ALSA lib conf.c:4259:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory
ALSA lib conf.c:4738:(snd_config_expand) Evaluate error: No such file or directory
ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM default
Playback open error: -2,No such file or directory

我的用户在音频组中，我完全sudo apt-get upgrade。不知道为什么我的声音不起作用。
