Yes I thought about that before and set a gap of 1 second between tracks:
same result.
So I upgraded my kernel to the latest 3.14 on OpenSuse 13.1 and the behavior
is different.
I still can not play tracks with different sample rate but if I stop the
play with mediacenter and start it again, it works.
What happens when you use aplay to play a (say) 44.1/16 and when it is done play a (say) 96/24? Does that work?
Back when I was using the Schiit through USB I had problems getting that transition to work.
Also maybe try a different media player (I suggest Guayadeque because I know you can talk directly to Alsa and you can turn off the track "blending").
It's far from perfect, but better an a way.
I see in messages this message when I try to play the first time:
linux-htpc kernel: [ 7476.413271] ALSA sound/usb/clock.c:391 current rate
96000 is different from the runtime rate 44100
You might want to look at the source above. This rings a bell for me. You might see some code to do something like a stream close / open; maybe it's not happening with your device?
When I stop the play:
linux-htpc kernel: [ 7576.789042] ALSA sound/core/pcm_native.c:1544 playback
drain error (DMA or IRQ trouble?)
Then when I play again, it works fine without further logs.
The guys at JRiver think it is a firmware error. I doubt that.
Erm... well there are other things to try before blaming the firmware.
So I have no more idea in mind to carry on my investigation.
