Sudden shifts in imaging (phase shifts?) (solved)

[buckaroo]

Hi, all -- I'm running a Hifiberry DAC+ Pro on a Pi3 with Runeaudio 0.4 and am having a strange problem. Occasionally I will perceive a sudden change in the soundstage imaging, with instruments, vocals, etc. hopping quickly to different parts of the image. It sounds almost as if something is introducing phase shifts in to the output, shifting the phasing of the drivers. Often I've heard a soft "pop" accompanying this shift. This has happened on a variety of recordings, and does not repeat in the same position of the song, so I'm certain it's either a hardware or a software issue. Can someone comment on what might be causing this, and what a possible solution might be? Thanks!

Hi buckaroo,

Hi, Frank -- that certainly does sound similar to my problem, even though I'm not getting a complete channel swap. I'll give the advice there a try and see what happens. Thanks!

One additional data point: Rune seems to think that I'm running a Pi2, according to the System Status display in the UI. I'm actually running a Pi3. I don't know if that would make a difference, but I thought I'd mention it.

Does this mean that there is no fix yet for the channel swap problem on Pi3, since I can't properly update the kernel?

buckaroo, I'm running a RP2 and hifi DAC+ compatible HAT and got this fixed. I'd suggest you read the link that Frank provided above. I might have used that to fix my issue (basically update to 0.4 with a new kernel). I can provide at uname -a if it helps.

I don't recall all the steps but I'm enjoying my Rune experience.

Thanks, surfninja - my problem is that those steps don't work for me, apparently because of the error that I'm getting while attempting to update the kernel. I'm hoping that there's a solution to that problem. I should then be able to fix the channel swap problem.

Searching the Arch Linux ARM site, the package "raspberrypi-firmware-bootloader" doesn't exist, which may be why I'm getting my error. However, there is one called "raspberrypi-bootloader". Is that the one I should be using?
