我目前正在尝试使用 ALSA 库来发出声音。但是，我收到以下错误：

Setting random seed to 345.
Adding stimulus TestBeep...
ALSA lib pcm_hw.c:1829:(_snd_pcm_hw_open) Invalid value for card
Process Process-1:
Traceback (most recent call last):
  File "/usr/lib/python3.8/multiprocessing/process.py", line 315, in _bootstrap
    self.run()
  File "/usr/lib/python3.8/multiprocessing/process.py", line 108, in run
    self._target(*self._args, **self._kwargs)
  File "../soundstimulus.py", line 36, in run_playback_process

  File "../soundstimulus.py", line 32, in run_playback_process
    playback_system = ALSAPlaybackSystem(device_name, config, file_dir, control_pipe, log_directory)
  File "../alsainterface.py", line 214, in __init__
    self.adevice = alsaaudio.PCM(device=device)
alsaaudio.ALSAAudioError: No such device [hw:CARD=SoundCard,DEV=0]

我想我确实有一张声卡，如下所示：

$ cat /proc/asound/card0/pcm0p/info
card: 0
device: 0
subdevice: 0
stream: PLAYBACK
id: ALC269VC Analog
name: ALC269VC Analog
subname: subdevice #0
class: 0
subclass: 0
subdevices_count: 1
subdevices_avail: 1

那么有一个 是什么意思invalid value for the card？有没有办法可以编辑它以使值有效？

我不确定以下内容是否相关，但很多 stackOverflow 帖子建议 OPs run aplay -l。我的结果是

aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC269VC Analog [ALC269VC Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
