Fedora 29 通用 USB 耳机没有声音

2024-6-2 • tag-icon

我买了一个通用 USB 耳机（通用 USB PnP 声音设备），它已被系统检测到，顺便说一下，我正在使用 Plasma KDE，但它对我有用一次，持续大约一秒钟，然后就没有任何效果。声音太大了，当我降低声音时，声音就永远消失了......

耳机工作正常，我在其他系统上测试过；-)

这是插入时 dmesg 在设备上报告的内容： [ 266.130515] usb 1-1: new full-speed USB device number 4 using xhci_hcd [ 266.261251] usb 1-1: New USB device found, idVendor=1908, idProduct=2070, bcdDevice= 1.00 [ 266.261257] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 266.261262] usb 1-1: Product: USB PnP Sound Device [ 266.261265] usb 1-1: Manufacturer: Generic [ 266.261269] usb 1-1: SerialNumber: 〲㌱㈱ [ 266.266899] input: Generic USB PnP Sound Device as /devices/pci0000:00/0000:00:14.0/usb1/1-1/1-1:1.3/0003:1908:2070.0004/input/input19 [ 266.319125] hid-generic 0003:1908:2070.0004: input,hidraw3: USB HID v2.01 Device [Generic USB PnP Sound Device] on usb-0000:00:14.0-1/input3 [ 266.501539] usb 1-1: 1:1: cannot get freq at ep 0x2 [ 266.502698] usb 1-1: 2:1: cannot get freq at ep 0x82 [ 266.512415] usbcore: registered new interface driver snd-usb-audio [ 266.537982] usb 1-1: 2:1: cannot get freq at ep 0x82 [ 266.600304] retire_capture_urb: 4 callbacks suppressed
