Stereo channels are swapped

giaur500

Hello,

I just noticed stereo channels are swapped, left channel played as right and right is played as left one. Is there any software solution to swap them back?

I checked schematic and you are right Good catch! Funny though that they also switched GND and TV signal, at least according to the cable which can be bought along...

Probably some ALSA config file like this http://superuser.com/a/59488 The easiest solution would be to put this in alsa config file located https://github.com/jernejsk/Open ... rds/audiocodec.conf and rebuild the image.

Will it swap channels for hdmi too? Actually, better if not, because hdmi is ok. Now I just prepared crossed cable...

No, that configuration file is only for analog out. And HDMI can't be mixed up as it is digitial interface. Nothing would work if that would be the case.

First I have to devise a system for applying it only to those boards which needs them. Only Oranges have this problem.

You can try this .config/asound.conf.
I'm in success.

1. pcm.!default {
   
2.     type route
   
3.     ttable.0.1 1
   
4.     ttable.1.0 1
   
5.     slave.pcm {
   
6.             type hw
   
7.             card audiocodec
   
8.             device 0
   
9.     }
   
10.     slave.channels 2
    
11. }
