ALSA无法正常工作RPI 3 - 扬声器测试失败

Question

我最近在Raspberry Pi 3上安装了Jasper，但运行后遇到了一堆ALSA错误。因此，我试着简单地运行扬声器测试，但收到相同的错误。

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 pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM default

我的用户是在音频组，我完全sudo apt-get升级。不知道为什么我的声音无法正常工作。

这个固定：

尝试增加dtparam =音频=上到/boot/config.txt
