TL;DR;卸载专用 GPU 后,我的 USB DAC 停止工作。
我的电脑运行的是 i5 12600k 和 GTX 1080。昨天,其中一个 GPU 风扇停止工作了,所以我卸载了它,并将显示器连接到主板上的 DP 端口,使用集成的英特尔 GPU 运行。
突然,我的 USB DAC(支持 UAC 2.0)在这台机器上停止工作。系统识别它,我可以选择它作为输出设备,但没有声音。这在 Win 11 和 Fedora 38 上都发生过(我双启动这台机器)。
我尝试过以下方法:
- 尝试了不同的 USB 端口
- 尝试过 USB 集线器
- 尝试了不同的电缆
- 尝试更新驱动程序
- 尝试卸载 DAC
它们全都不起作用。
还有几件事:
- 我的其他 USB DAC 仍可在这台机器上使用
- 这款 DAC 适用于我的 Windows 笔记本电脑
这太奇怪了,我不知道该如何处理。任何帮助都将不胜感激。谢谢!

说“我的其他 USB DAC 仍可在这台机器上使用”并不完全准确。在 Fedora 上,我尝试使用我的其他 DAC 之一收听音乐/视频,结果它卡得厉害……
