    at present i am working with a ADAV801-based CODEC-board, which works fine and is easy to handle by setting the approriate registers.

    In addition now  i want to use the ALC-function of the ADAV801 because the ADC Input level is not well defined …

  • ADAV801 I2S to SPDIF


    One of my project which require an audio device capable of outputting digital audio (SPDIF) from I2S.

    I found this sequence for this usage:

    #define ADAV80X_PLAYBACK_CTRL 0x04
    #define ADAV80X_AUX_IN_CTRL 0x05
    #define ADAV80X_REC_CTRL 0x06

  • ADAV801 duty cycle error


    a question regarding the SYSCLK2 output on ADAV801.

    At XIN I have a 27MHz crystal, at SYSCLK2 I need 24.576 MHz with 50% duty cycle.

    Because I use PLL2 and double sample rate (48 kHz x 2), I need to write in register 0x75 the value 0x10.

  • Problem encoding analogue audio with ADAV801


    I am attempting to add ADAV801 codec support to my 2.6.35 kernel to be
    used with an ARM processor. I can see that there is a mainlined
    adav80x.c driver that appears at kernel version 3.1, I have had a
    quick look at back-porting the driver but this looks…

  • ADAV801: Change LRCLK at Serial Output Port from 96kS to 192kS

    if I use these settings (please see attachment for more information), I measure
    a LRCLK of 96 kS/s on the I2S interface at the serial output port, but we need 192 kS/s . Which register settings would be
    necessary for it?

    If I put a 192 kHz SP…
