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

SCerovec · 11-01-2016, 09:22 AM

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

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

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

@thecarpy
Glad it helps, was my aim tho.

Did it work out for You?
