Kernal Panic with MP3 files

repeet

Hello, noob here with a strange problem.

I have a problem when I try to play mp3 files through a USB DAC, the Odroid C1+ locks up with Kernal Panic and I have to power cycle it.

I have tried 3 different DAC's - Weiliang DAC 5 with Tenor TE7022usb, Hifimediy Sabre dac and Audio GD NB15 and they all do the same.
FLAC files play perfectly fine and playing through HDMI is ok. I also tried another dac with cm108 receiver and was ok.

I tried Volumio and it did the same, there is a fix in there forums to add:

options snd-usb-audio nrpacks=1

This fix doesn't work in Runeaudio and I would prefer to use it over Volumio. Any help would be much apreciated.

Hi repeet,

your debug data shows:

###### Kernel module snd_usb_audio settings ######
Module = "snd_usb_audio"
 
  Attributes:
    coresize            = "121676"
    initsize            = "0"
    initstate           = "live"
    refcnt              = "0"
    taint               = ""
    uevent              =
 
  Parameters:
    autoclock           = "Y"
    device_setup        = "0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0"
    enable              = "Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y"
    id                  = "(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null)"
    ignore_ctl_error    = "N"
    index               = "-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1"
    nrpacks             = "8"

So in your config nrpacks is set to 8.

options snd-usb-audio nrpacks=1

Where did you set this option?

This should be set in /etc/modprobe.d/modprobe.conf.

Thanks for the reply Frank, I'm really going to need my hand held with this. I'm afraid I don't understand what you are asking.

In Volumio I entered the following and then it worked:

sudo echo 'options snd-usb-audio nrpacks=1' >> /etc/modprobe.d/alsa-base.conf

This does not work in Rune, I'm not sure what to do next???

Really appreciate your time.

Hi repeet,

go to the console (as you did in Volumio) and type this:

nano /etc/modprobe.d/modprobe.conf

Edit this file so it looks like this:

options snd-usb-audio nrpacks=1

Hit "CTRL-X" followed by "y" to save the file.
