Hello forum,
I am new to Armbian. Selected it for my Odroid N2+ because I need high CPU performance for a virtual piano software and current Armbian Buster comes with 2.4 GHz.
I'd like to share my alsa settings for the analog stereo output of the N2+.
Could not find much info on the net, but at least I have analog sound now at the 3.5mm TRS-jack -- don't know really, why it works, but it does
Created a /etc/asound.conf with
pcm.!default {
type plug
slave {
pcm "hw:0,1"
}
}
(sets analog stereo device as default).
The alsamixer settings I made manually. The following is the output of the command amixer:
