Hi Guys!
I want to make Bit-Perfect Audiophile Music Player and have some questions..
Could you please clarify what audio codecs are supported by this board?
Is be used integer or fractional clock dividers?
How good is quality of upsampling and downsampling of this CPU?
Would be able to support 44.1 KHz sampling frequency without any resampling?

    The board has audio through the HDMI interface.
    You can also attach an USB soundcard to it.

    I know it! How about using interface 40 pin to connect I2s DAC?
    Could you please clarify what audio codecs are supported by this board? I attend to use AK4494s I2s DAC. Is it possible?

    What I2s audio codec is used?

    I2S support is currently not enabled in Linux. We are working on it but we are waiting for an input from Intel.
    At first we will be enabling the HiFiBerry family of boards (https://www.hifiberry.com/products/dacplus) that uses a PCM5122 codec and to obtain I2S output on the hat.

    If you have a custom codec once we get that to work you can add your custom Linux machine driver to support it.

    For now as I said your best options is to use an external USB sound card.

    Will Up Board work in Slave mode after it be connected to I2s DAC and this DAC will be work in Master mode ?

    Hi
    currently I2S is not enabled due to a bug with the Intel driver.
    as I said earlier we are working on solving the issue
