Left and right are switched

[dudess]

Hi people,

I installed the hat on an out of the box Raspberry Pi 3 B, and I notice that when I playback on Youtube or on PureData the left and right channel are the wrong way round. Since I am using it for high quality binaural soundscaping, this is a little setback. I just use the jack output (I think its called jack right?).

Would any of you know how I get this right software wise? Or is it in the hardware?
I am not a super experienced linux person, so I really hope somebody could walk me through what to do here

Best regards,
Dudess

Ps. Also if I try to use iPhone earplugs instead of a pair of headphones, they don't fit. I have to keep pressing the plug into the thing to hear both channels. So I switched to these headphones instead which seem to work fine.
The headphones are otherwise fine, because the channels come out alright when its plugged into my computer.

I think you will find that on the original stereo card, the headphone jack has its L+R reversed. This is now fixed on the Audio injector Zero card.

There is a post here detailing how to switch left and right in software. It is a very simple .asoundrc file which is required to make the fix. The same can be done if you want to reverse left and right RCA lines - which should already be the correct way around (red on right).

thanks
Matt

Thanks for the info flatmax! I'll try the suggested solution when I get to spend some time again with my project. If you hear nothing that means I got it fixed.

Thanks again,

Dudess
