    Best way to organize USB AUDIO OUTPUT from PC ?

    Hi!

    Today I was wondering if the way of connecting a USB cable from my external soundcard to PC matter or not.
    I can connect my external soundcard to PC using 2 global ways:

    1) Using standard motherboard USB outputs
    1.a)
    USB Outputs on the back panel of motherboard USB2.0/3.0
    1.b)
    USB Outputs on the motherboard connectors like USB2.0/3.0 outputs for the front panel.

    2) Using PCI-e USB card
    2.a)
    Using CPU PCI-e slots
    2.b)
    Using PCH PCI-e slots

    In all of these ways USB bandwidth may be processed by different controllers and go thru different data paths.
    Which of these 4 ways: 1.a, 1.b, 2.a, 2.b is the best for the cleanest, uninterrupted, less-noise USB audio transportation and why?

    Best way to organize USB AUDIO OUTPUT from PC? (MAXIMUS VIII RANGER)

    Hi!

    I have ASUS MAXIMUS VIII RANGER motherboard.

    I use my computer for high-quality music playback, and I'm interested in the best possible USB audio OUTPUT from my PC to external DAC and external sound cards. I have one external DAC and two external soundcards. 3 USB ports dedicated to external USB audio devices.

    Today I was wondering if the way of connecting a USB cables from my external soundcards to PC matter or not.
    I can connect my external soundcards to PC using 2 global ways:

    1) Using standard motherboard USB outputs
    1.a)
    USB2.0/3.0 outputs on the back panel of the motherboard :
    KBMS_USB78
    USB910
    USB3.1_EC1
    USB3.1_EA2
    USB3_56
    1.b)
    USB2.0/3.0 outputs on the motherboard itself for the front panel:
    USB3_34, USB3_12, USB1314, USB1112

    2) Using a dedicated PCI-e USB card
    There are many PCI-e x1 into 4 USB ports cards.
    In the first PCIEX_X16/X8_1 CPU PCI slot I have GTX1080, and I cannot use second CPU PCIEX_X8_2 slot for PCI-e USB card because first x16 slot switches into x8 mode.
    Because of that, I can use only PCH PCI slots for dedicated PCI-e USB card:
    PCIEX1_1
    PCIEX1_2
    PCIEX1_3
    PCIEX4_3

    In all of these ways, USB bandwidth may be processed by different controllers and go thru different data paths, may interfere with my SSD and so on.

    Which of these 3 ways: 1.a, 1.b, 2 is the best for the cleanest, uninterrupted, less-noise USB audio transportation and why?

    If you are not getting any skips in your audio then there isn't a problem. USB is digital so it's not possible to get static. Audio requires so little bandwidth (even lossless) that it's not really something to worry about. I would arrange things so they best fit your workflow, wire routing, etc.

    I noticed there were two threads for this. I merged them. Please maintain one thread per issue. Thanks.

    I meant the model name of the audio device

    Really should not matter which USB port (2.0, 3.0, 3.1, etc) you use to connect the PC to the external sound card.

    usb induce input lag/latency, i had issues with gaming, fps issues, inconsistent mouse sensitivity etc. i have a creative X7 dac. use toslink from the motherboard it's far better and quality is the same.
    i think pci express isn't perfect too since it's still an external peripherical, there is still some latency involved and it's not as fast as integrated + toslink, don't remember precisely from the time i had a xonar soundcard.
