audio - 在树莓派零中未检测到 USB 声卡 w

问题描述

我有树莓派零 W，运行 raspbian lite。我正在尝试连接 USB 声卡。

USB 卡被“dmesg”命令识别但未添加为声卡：

dmesg：

解决方案

I was having the exact problem on RPi4. Once I blacklisted the built-in sound card, following these instructions: https://www.instructables.com/Disable-the-Built-in-Sound-Card-of-Raspberry-Pi/ the usb sound card was recognized and it worked.
