Shure MV7 USB麦克风似乎适用于Thinkpad，而不是XPS。
Shure MV7 USB麦克风似乎适用于Thinkpad，而不是XPS。
提问于 2021-02-18 22:00:58
我有两台Linux笔记本电脑。它们都在运行Kubuntu20.04.2并使用5.10内核。一台笔记本电脑是联想的Thinkpad T14s AMD，另一台是戴尔的XPS 13，两者都安装了脉冲音频13.99.1。
我还有一个Shure MV7 USB麦克风和两个不同的接口；一个是USB，另一个是回到USB的TB3端口( T14s AMD不支持TB3，T14s确实支持)。
使用任何一个基座，Thinkpad都可以与麦克风一起工作。使用这两个端口，XPS 13无法与麦克风一起工作。MacBook Pro拥有TB3，它可以使用任何一个码头与麦克风一起工作。
下面是工作Thinkpad的dmesg输出：

Bus 005 Device 014: ID 14ed:1012 Shure Inc.关于如何让麦克风与XPS 13一起工作，有什么想法吗？在USBC适配器上插入基本的USBC也不起作用.
请注意，XPS绘制45W的功率，而Thinkpad绘制65W，所以我不认为问题是，码头不能同时供电XPS和麦克风。
更新2021-02-27:
我将XPS上的内核更新为5.11，但这并没有帮助。
下面是一系列来自不同命令的输出。对于其中的大多数，我删除了与MV7无关的条目。

首先，MV7使用Ubuntu (18.04)在我的桌面pc上工作得很好。
在重新插入一些USB设备之后，我遇到了类似的问题:用消息连接/断开连接循环：
1:1: usb_set_interface failed (-71)虽然(USB)摄像头和视频流是口吃。我恢复了回答，一切都很好:对我来说，“修复”是使用USB2，而不是使用MV7的USB3插槽。
看起来，USB3问题不仅与MV7：https://askubuntu.com/a/1199300有关。

我有Ubuntu20.04上的戴尔XPS 159550，并面临同样的问题，麦克风将无限地重新启动。
基于关于这个答案，问题似乎是PulseAudio与麦克风的通信方式使麦克风的固件崩溃。
我用PipeWire代替了PipeWire，现在MV7工作得很好。我使用了以下PPA：https://github.com/pipewire-debian/pipewire-debian#1-ppa-configuration
请确保按照有关禁用PulseAudio服务的说明进行操作，并在该事实发生后重新启动系统。
