Digi+ , Rune and USB drive = channel swapping

[piknik]

Currently having an issue when playing a file (FLAC), the channels will swap several times during a song. Sometimes it's very subtle, while other times it's quite jarring. The issue only occurs when accessing a mounted USB drive source. When accessing a network mounted source, the files play perfectly.

Hardware: RPi3 with Hifiberry Digi+ board. USB powered Toshiba Canvio Connect hard drive and Canakit 5V 2.5A p.s.
Software: beta 4 image (03212016)

This issue has been discussed at the Hifiberry forum
https://support.hifiberry.com/hc/en-us/ ... nd-DAC-Pro

and here, but pertaining to the DAC Pro boards, not the Digi+.

Has RuneAudio been able to duplicate this issue, and if so, is RuneAudio also working with Hifiberry on a fix. It sounds like it's a kernel issue and Hifiberry folks are in touch with the Volumio people, so hopefully parallel efforts are going on here.

Thanks and great product.

Bingo! That did it.

After doing your suggested changes and listening for a couple of hours, I haven't heard the channel swapping at all...not even once. I am ecstatic. And to top it off, I can use the full capacity of my mSD card now.

Frank, thanks so much for your quick help, very much appreciated.

So, can these instructions be used with the Raspberry Pi 2B and DAC+, or is this specific to the Raspberry Pi 3 and DIGI+?

Hi,

as both (RP2/RP3) share the same image this should work.
