This motherboard comes with 5x USB Controllers:
Code:
[1022:148c] 04:00.3 USB controller: Advanced Micro Devices, Inc. [AMD] Starship USB 3.0 Host Controller
[1022:148c] 25:00.3 USB controller: Advanced Micro Devices, Inc. [AMD] Starship USB 3.0 Host Controller
[1b21:3242] 44:00.0 USB controller: ASMedia Technology Inc. Device 3242
[1022:149c] 48:00.1 USB controller: Advanced Micro Devices, Inc. [AMD] Matisse USB 3.0 Host Controller
[1022:149c] 48:00.3 USB controller: Advanced Micro Devices, Inc. [AMD] Matisse USB 3.0 Host Controller
But the DSDT shows 6x USB Controllers:
Code:
Scope (_SB.PCI0.D0B8)
    Device (XHC0)
    {
        Name (_ADR, 0x03)  // _ADR: Address
    }
}

Scope (_SB.PCI0.D1B8)
    Device (XHC0)
    {
        Name (_ADR, 0x03)  // _ADR: Address
    }
}

Scope (_SB.PCI0.BR58)
    Device (XHC0)
    {
        Name (_ADR, 0x03)  // _ADR: Address
    }
}

Scope (_SB.PCI0.BYD8)
    Device (XHC0)
    {
        Name (_ADR, 0x03)  // _ADR: Address
    }
    Device (XHC1)
    {
        Name (_ADR, One)  // _ADR: Address
    }
}

Scope (_SB.PCI0.BR78)
    Device (XHC0)
    {
        Name (_ADR, 0x03)  // _ADR: Address
    }
}
My question is, why does the OS only see 5x when DSDT has 6x and all the XHC0 controllers are at 'Name (_ADR, 0x03)'. I am trying to figure out power management in Linux because I am getting a ton of audio issues using the on board audio inputs/outputs on the system, which the audio controller resides on the USB controller. Any suggestions?

That is interesting. Not sure why the onboard audio is problematic. USB audio is cheap if the there is a problem.
