Raspi3 HifiBerry DAC+ - left right channel swaping/switching

Postby jones » 18 Apr 2016, 11:14

Hello,

i expierience a strange problem with my runaudio setup.

RasPi3
Hifiberry DAC+
7" original RasPi Display
runeaudio Version: RuneAudio_rpi2_rp3_0.4-beta_20160321_2GB

So my problem is:
sometimes in a song the sound from the speakers is changing so that the left channel is on the right speaker and the other way around. :shock:

its only happening occasionally and not reproduceable. sometimes it is switching left to right and right to left and back in a few seconds.

really strange... first i thougt its on the recordings ad listened to the recordings over and over. then i listened to songs where there is a strong left to right difference (instruments).

Im now testing if this is related to "sound signatures". Are the sounds ignatures working on the RasPi3 ?

Hi jones,

you are not the only user with this issue.
pi3-and-dac-pro-t3293.html?hilit=channel%20swap

My problem is that i'm unable to reproduce this.
I will do a few more test.

Hi jones,,

with my setup (Rp3, 7" TFT, Hifiberry DAC+, Wifi) i have absolutely zero channel swapping.
Is your DAC the standard or the pro version?

Hi Frank

I have the same problem with my rpi3 with hifiberry digi+, Not often but sometimes, and it is a smooth swift, not any click or pause in the music.

All best

Hi,

there is news on that matter from Hifiberry. They identified it to be some kind of kernel related problem.

Tobi

FYI: the bug report.

Hi tobvc,

tank you for reporting this.

I'll submit a bug report to the Linux RPi kernel development forum and hopefully we'll get this issue resolved.

All the best,

Stuart


Please keep an eye on this and report here.
