Correction to the above. It does work. 
I had to select the newly created device in the Audio Settings, and now it works.
I have no idea however if the LFE (low frequency enhancement) channel will be set correctly.
But so far so good.
Thanks a lot for the ideas, and long live LibreElec Kodi for RPI.
Hi I think I have a similar issue with my USB speakers.
I'm on LibreElec 10.01
I have a Microsoft Digital Sound System.
On LibreElec 9.xx it used to work out of the box.
Now I only have sound on the left speaker.
Here's the log: http://ix.io/3Ptn
I tried to create the a /storage/.config/asound.conf file with the following content:
pcm.myoutput {
type hw
card "System"
chmap [ "FL,FR" ]
channels 2
hint.description "my output with fixed chmap"
}But that did not work.
The output of amixer -c System is
