帮助解决我的蓝牙问题

我认为这台机器上的蓝牙可以工作，至少硬件可以。我已经看到它短暂地运行过一次，这意味着它可能运行的时间不止几秒钟。

我遇到了这个问题，但能够让它消失： https ://askubuntu.com/questions/690863/sound-fluctuates-wildly-back-and-forth-as-sound-device-rapidly-appears-and-disap

我有这个硬件：

sudo bluez-test-adapter list
 [ /org/bluez/599/hci0 ]
    Name = warmachine-0
    Powered = 1
    Devices = dbus.Array([], signature=dbus.Signature('o'), variant_level=1)
    DiscoverableTimeout = 0
    PairableTimeout = 0
    Discoverable = 1
    Address = 24:0A:64:03:BF:94
    Discovering = 0
    Pairable = 1
    Class = 0x000000
    UUIDs = dbus.Array([dbus.String(u'00001000-0000-1000-8000-00805f9b34fb'), dbus.String(u'00001001-0000-1000-8000-00805f9b34fb'), dbus.String(u'0000112d-0000-1000-8000-00805f9b34fb'), dbus.String(u'00001112-0000-1000-8000-00805f9b34fb'), dbus.String(u'0000111f-0000-1000-8000-00805f9b34fb'), dbus.String(u'0000111e-0000-1000-8000-00805f9b34fb'), dbus.String(u'0000110c-0000-1000-8000-00805f9b34fb'), dbus.String(u'0000110e-0000-1000-8000-00805f9b34fb'), dbus.String(u'0000110a-0000-1000-8000-00805f9b34fb'), dbus.String(u'0000110b-0000-1000-8000-00805f9b34fb')], signature=dbus.Signature('s'), variant_level=1)

我这里有几个蓝牙设备，我的手机和耳机，但它们根本不扫描。...但我已经看到这台机器注册了蓝牙设备，它们只是不会保持这种状态，之后您根本无法扫描任何东西。
