LinuxQuestions.org - [SOLVED] A20 Allwinner/Banana PI sound not working on ARM-current out of the box on kernel 4.8.1 and 4.8.4

- Slackware - ARM (https://www.linuxquestions.org/questions/slackware-arm-108/)

- - A20 Allwinner/Banana PI sound not working on ARM-current out of the box on kernel 4.8.1 and 4.8.4 (https://www.linuxquestions.org/questions/slackware-arm-108/a20-allwinner-banana-pi-sound-not-working-on-arm-current-out-of-the-box-on-kernel-4-8-1-and-4-8-4-a-4175592650/)

A20 Allwinner/Banana PI sound not working on ARM-current out of the box on kernel 4.8.1 and 4.8.4

Code:

modprobe -av sun4i-codec

is failing silently.

microphone registers on XFCE pulseaudio mixer (shows level of ambient sounds)

any comand using sound "hangs" and won't "run" untill

Code:

kill -9 {PID}

I will report back :)

Okay,
i've tried many things so far.
but got it working somehow ???
file:/etc/asound.conf,

Code:

# ALSA system-wide config file

# By default, redirect to PulseAudio:



 pcm.default pulse

 ctl.default pulse



    pcm.!default {

        type hw

        card 0

        device 0

    }

    ctl.!default {

        type hw

        card 0

    }

and chmod +x to rc.pluseaudio and rc.alsa

I need reboot yet and check what's needed and what not...

gave few edits to the /etc/asound.conf file:

Code:

# ALSA system-wide config file

# By default, redirect to PulseAudio:



    pcm.!default {

      type hw

      card 1  #If you want to set HDMI as output ,turn 0 to 1.

      device 0

    }

    ctl.!default {

      type hw

      card 1  #If you want to set HDMI as output ,turn 0 to 1.

    }



    pcm.pulse {

      type pulse

    }



    ctl.pulse {

      type pulse

    }

public code from lemaker forum

and it beeps:

Code:

play /usr/share/orage/sounds/KDE_Beep_Digital_1.ogg

works

case closed :D

Thanks for the info, I was looking for just this ... great thread, the guy asks question, works out solution and posts the lot.

+1

Update:
only alsa needs be executable, pulseaudio manages somehow without?

@thecarpy
Glad it helps, was my aim tho.:hattip:

Did it work out for You?
