I have some weired problems with my DAC. I have a PiFi DAC+ with PCM5122 vom TI. The PI is a RPI 2B.
I installed volumio 1.55 and everything is running fine. If I choose Best sinc interpolator in settings I get stuttering sound at 384 KHz. MPD is running at 105%. If I switch back to fastest sinc interpolator everything runs as expected.
I disabled transcode settings so I do not understand why the interpolator makes any difference.
If I do an apt-get upgrade, I get always stuttering sound at 384 KHz regardless the settings I choose.
Maybe RPI is too weak even in turbo mode.
Any hint would be great.
