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=32
framebuffer_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
