AM3517 arm linux 驱动 realtek的alc5621后,设备文件/dev/snd有了controlC0 pcmC0D0c pcmC0D0p timer, 但在执行 cat high.wav > /dev/snd/pcmC0D0p时, 提示cat: write error: File descriptor in bad state。 用的瑞泰的开发板,他用的TI tlv320aic23,驱动是正确的,但还是有这样的提示。 cat high.wav...

提示cat: write error: File descriptor in bad state。 用的瑞泰的开发板,他用的TI tlv320aic23,驱动是正确的,但还是有这样的提示。 cat high.wav > /dev/snd/pcmC0D0p怎么会有问题呢?我应该如何测试音频? 希望各位能帮助一下我。任何发言都有可能对我有益。谢谢。
