I installed Squeezelite on two ARM linux microsystems (piCorePlayer on
Pi2 and max2play on Odroid U3). The player is connected to an USB-DAC
(Emotiva XMC-1).
When I was running Squeezlite togehter with LMS on the same system,
frequent glitches between two songs were annoying. Now I switched
Squeezlite to the Pi2 running pICorePlayer, because I suspected LMS and
Squeezelite not running smoothly on the same system. But the problem
persist. It sounds like the audio stream output gets interrupted for a
short time. The DAC shows the same glitches over HDMI when it receives a
new audio stream. Or maybe the two songs are not correctly appended?
Can somebody help debugging this problem?
On transitions from MP3 to FLAC (same samling rate), the glitch is heard
every time. The debug log of Squeezelite for such a transition with a
glich is:
