Not Getting Any Sound Card for Alsa In Up board Audio HAT ( Ubuntu 16.04 )

hemilhemil Posts: 4New Member

I have recently purchased Up Board with Up Board Audio HAT and as connected both the devices and trying to play audio in Ubuntu 16.04, but found that no audio is coming out from Up Board Audio HAT (3.5 mm jack).

I have listed out the audio cards present in ALSA using aplay -l, and i have found card 0 with 3 sub-devices of Intel-HDMI/DP LPE Audio and card 1 with 2 sub-devices of bytcht-nocodec (not sure if these are sub-devices of audio HAT).

I have tried to play audio from HDMI card 0 with all the different sub-devices and found that only from sub-device 2 we are able to get sound rest 2 are nor working.And card 1 is totally not working.

So, Kindly help me out to get sound in Up Board Audio HAT with Ubuntu. The IC used in the device is Realtek ALC5672.

    Hi @hemil ,

    Which kernel are you using for the Ubuntu 16?
    Please, confirm you have the latest UP kernel and try again:

    Hi @ccalde ,

    I am already using "Linux 4.15.0-37-generic #40~upboard03-Ubuntu SMP" kernel version for Ubuntu 16.

    These are the results after following the installation process from "https://wiki.up-community.org/Ubuntu#Install_Ubuntu_kernel_4.15.0_for_UP_from_PPA"

    We have also tried Installing Ubuntu16.04 using Bootable Ubuntu USB Drive, but the results are the same.

    uname -a
    "Linux username 4.15.0-37-generic #40~upboard03-Ubuntu SMP Wed Dec 12 16:21:24 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux"

    aplay -l

    The Kernel version is updated. ** We are getting AudioOut on HDMI(0,2) only while doing speaker test, other than that no audio out is working.**

    I confirm that after upgrading to this kernel, the audio disappeared! Is the patch for Atom implemented in this release?
