So I've tried dx90 dac with rune audio on raspberry pi 2, the music plays but has gap(silence) every 2 or 3 seconds while playing.
I've tried changing the audio buffer size in rune audio configuration page but it doesn't help,
anyone here have any idea?
P.S. rune audio is a arch linux based operating system design for raspi 2 to play music
my setup: usb stick > raspi 2 > dx90(linux dac) > earphone (gap problem)
setup 2: usb stick > raspi 2 > xonar u7 > earphone (works fine)
also a quick note it works perfectly when I use xonar u7 as dac,
the gap problem only comes up when I use dx90 as dac connect to raspi 2.
I reported this silence issue a month ago, testing dx90 as a DAC with raspberry pi 2 installed with Linux but no one bother about it.
Also an update on this, dx90 had failed to get recognize as DAC on raspi 2 with rune audio or volumio,
it worked initially (with silence problem) when I pluged in the dx90,but after few second the music hangs completely,
display screen started to go crazy, switching between charging screen, playback screen and DAC screen, just like dx90 had no idea how to handle the usb connection towards raspi 2.
Of course on raspi 2 side, it also had lost connection to dx90 and failed to identify the device as a DAC(no dx90 to selected in external DAC list).
Both raspi 2 rune audio and volumio are using ALSA as their main audio driver to identify DACs and process audio just like other Linux system,
I've also tried dx90 connect directly to an ubuntu Linux machine and it works with ALSA but have silence problem (ubuntu successfully identified dx90 as DAC).
Dx90 is one piece of great machine, if it could also work with raspberry pi 2 Linux hifi music players (rune audio or volumio) that would be even better.
