未播放声音时 USB 声卡会重置

我的 USB 声音接口 (M-Audio Fast Track Ultra 8R) 工作正常，但当我停止播放声音时，它似乎在大约 5 秒后“关闭”（绿灯弹出，这仅在您启动设备时才会在 Windows 上发生 - 而且我听到很大的爆音，这很烦人）。一旦我在声音“关闭”后启动声音，同样的问题就会再次出现（就像它“启动”一样）。似乎驱动程序告诉设备由于没有播放声音而关闭。

有没有办法来解决这个问题？

以下是一些输出：

你好吗？

您尝试使用 ACPITOOL 吗？

使用 acpitool -w 确定 USB 控制器的可用唤醒级别。

在我的系统上运行此命令显示 USB 控制器的 S1：

$ acpitool -w 设备 S 状态状态 Sysfs 节点

  1. LID S3 *已启用
  2. PBTN S4 *已启用
  3. PCI0 S3 *已禁用无总线：pci0000：00
  4. USB0 S1 *禁用 pci:0000:00:1d.0
  5. USB1 S1 *禁用 pci:0000:00:1d.1
  6. USB2 S1 *禁用 pci:0000:00:1d.2
  7. USB3 S1 *禁用 pci:0000:00:1d.7
  8. MODM S3 *已禁用
  9. PCIE S4 *禁用 pci:0000:00:1e.0

要在启动后禁用它，你可以尝试

echo 1 > /sys/bus/usb/devices/你的 USB 设备 /power/autosuspend

回显“ on”> / sys / bus / usb / devices / your-USB-device / power / level

试试看……还有什么事的话，告诉我。小心点。
