audio - 设置Raspberry Pi 3 USB麦克风(创意声霸)

Question

有人可以帮助我设置我的RPi 3吗。我想用我的游戏耳机(Creative Technology，Ltd的Sound Blaster Tactic(3D)Sigma声卡)建立语音转文本/语音识别。扬声器现在正在工作，但是很遗憾，我无法设置麦克风。

在调整设置之前，我可以录制/创建一个wav文件，但是每当播放wav文件时都没有声音。更改某些设置后，我在下面遇到了新错误。提前致谢!

错误:

pi@raspberrypi:~ $ arecord -D plughw:0,0 test9.wav
Recording WAVE 'test9.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono
^CAborted by signal Interrupt...
arecord: pcm_read:2031: read error: Interrupted system call

配置:

〜/ .asoundrc

pcm.!default { type plug slave { pcm "hw:0,0" } }
ctl.!default { type hw card 0 }

/usr/share/alsa/alsa.conf

defaults.ctl.card 0
defaults.pcm.card 0
defaults.pcm.device 0
defaults.pcm.subdevice -1

/lib/modprobe.d/aliases.conf

options snd-pcsp index=-2
options snd-usb-audio index=0
options snd_bcm2835 index=1
options cx88_alsa index=-2
options snd-atiixp-modem index=-2
options snd-intel8x0m index=-2
options snd-via82xx-modem index=-2

# Does the reordering.
options snd slots=snd-usb-audio,snd-bcm2835

更新

我已经解决了这个问题!事实证明，当我运行alsamixer时，~/.asoundrc配置文件会自动更新。我的配置被新设置覆盖。
