英文:
ALSA: failed to import hw:0 use case configuration -2
问题
我已将声卡配置存储在一个名为asound.state的文件中，alsactl 能够正确读取它，但在启动期间以及我手动运行该命令时，日志中会出现以下消息：
alsa-lib ../../../git/src/ucm/main.c:1412:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -2
我不明白出了什么问题，也没有在网上找到太多信息。你有什么想法，可以让我修复这个错误，或者知道它的根源吗？
如果我运行 aplay -l 命令，会得到以下结果：
~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: mycard [mycard], device 0: 44004000.audio-controller-tlv320aic31xx-hifi tlv320aic31xx-hifi [44004000.audio-controller-tlv320aic31xx-hifi tlv320aic31xx-hifi]

谢谢。
英文:
I have stored the configuration for my sound card in an asound.state file and alsactl is reading it fine, but during boot and whenever I try running the command manually, this message appears in the log:
alsa-lib ../../../git/src/ucm/main.c:1412:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -2
I don't understand what is going wrong and I haven't found much online. Any ideas for how I could fix this error or what might be the origin of it?
This is what I get if I run aplay -l:
~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: mycard [mycard], device 0: 44004000.audio-controller-tlv320aic31xx-hifi tlv320aic31xx-hifi [44004000.audio-controller-tlv320aic31xx-hifi tlv320aic31xx-hifi]

Thank you.

经过更多的调查，我发现了这个命令，已经移除了错误消息：
alsactl --no-ucm restore
添加了 --no-ucm 部分后，问题得到了解决，所以问题可能是我的声卡不支持 UCM。
英文:
After some more investigation, I've found this command that has removed the error message:
alsactl --no-ucm restore
Adding that --no-ucm part has fixed it, so the problem was probably that my sound card doesn't support UCM.
