Well I posted there already, but didn't get an answer so far. I thought I'd try my luck here, since it's so similar and I had basically the same issue, when I had LibreELEC installed before.

My setup is:

Odroid C2

CoreELEC latest

USB sound card

On every reboot and sometimes while playing a movie or a song the default playback device jumps back to HDMI. That is really annoying and I’ve been trying everything to change it.

lsmod | grep snd returns:

snd_usb_audio         120679  0
snd_hwdep               6893  1 snd_usb_audio
snd_usbmidi_lib        20572  1 snd_usb_audio
snd_rawmidi            19496  1 snd_usbmidi_lib

cat /proc/asound/cards returns:

0 [AMLM8AUDIO     ]: AML-M8AUDIO - AML-M8AUDIO                      
                     AML-M8AUDIO
1 [USB�USB�USB�USB]: USB-Audio - USB̾USB̾USB̾USB̾USB̾USB̾U
                     C-M̾C-M̾C-M̾C-M̾C-M̾C-M̾C-M̾C- USB̾USB̾USB̾USB̾USB̾USB̾U at usb-dw

I tried adding the following line to ~/.config/modprobe.d/alsa-base.conf :

options snd_usb_audio index=0

That just makes USB sound disappear completely?! I suspect that’s because of snd_usb_audio index=-2 in /lib/modprobe.d/alsa-base.conf

I tried adding this to either ~/.asoundrc and ~/.config/asound.conf :

pcm.!default {
    type hw
    card 1
}

ctl.!default {
    type hw 
    card 1
}

Neither of which helped at all. Of course I did a full reboot after every change. I am desperate I don’t know what else to do… If anyone here could help, I’d be very greatful.

English is not my first language, so I appologize for any mistakes.
