Hello Jeremy,
It looks like it is much better on the non RT kernel.
I can't be sure it is not crashing anymore yet, but, for sure, it is more
stable.
Yesterday I have reverted to the NON RT Kernel as it was too stressfull.
And I may have an explanation for the crashes, I beleive that from time to
time the total memory of Pi is saturated. I have the feeling that
Squeezebox server is responsible for the crashes mainly because it
sometimes needs memory in excess while transcoding or something like that.
When I was running Jack + jconvolver + Squeezelite only on non RT kernel, I
didn't experience any crashes.
So Yesterday, I tried again everything on non RT and it didn't crashed.
And I also added the two following lines to config.txt, I don't know
exactly what it does, but i have the feeling it helps a little bit, even
with the RT kernel.
*framebuffer_depth=32framebuffer_ignore_alpha=1*
I will let everything running for a few hours in random mode, to see if it
crashes.
Anyway, I would like to know if the NEON stuff might help ? And if anybody
have an experience of building/running jconvolver with NEON ?
If it works, should also Jack and Squeezelite be built with the NEON ?
Thank you,
Jean

Hello Jeremy,
Most of the time, RPi2 send a continuous beep sound from the I2S DAC
output and is not anymore under control from putty, so, Yes it is RPi2 that
crashes.
Once upon a time, i have xruns errors although jackd is in softmode and
this whatever the buffer size.
I didn't experience problems when the RPi2 was running only
Jackd/jconvolver/Squeezelite (non RT).
I had the problem when running also squeezebox server (RT).
I had similar problems (buffer issues) with RPi2 was running
BruteFIR/Squeezelite/Squeezebox server, both RT and non RT.
I may have forgotten to try Jackd/jconvolver/Squeezelite + Squeezebox
server (non RT).
I will make this and report back.
Thank you,
Jean
