When asked to send files, please, stick with the member(s) list you are being provided with, as those agreed upon receiving files for analysis.

I didn't know I had PMs disabled, but either way, yes stick to the other guys, I'm no where near as clever as them with diagnosing files.

@Sehnsucht 

So I downloaded your two tracks to my SDCARD library, added them alternately to the queue 20 times each (ca 3 hours total playing time) and started playing the queue. 

I do see the CPU usage spike at 100 percent at the end of a track in htop and roughly the same bump in usage in top and moodeutl -m. However, I see this behavior whether or not parametric equalization is enabled (perhaps briefer with no PEQ but that's a subjective impresstion). This is, after all, just a single core Pi Zero.

I don't experience the "crash" condition you describe.

Maybe it's time you described your system. As a first step, we can use Tim's recurrent rejoinder

Quote:To start troubleshooting boot up your moOde 9 system and then post the contents of the startup log.

The log can be viewed via the SSH command moodeutl -l or downloaded via the Logs section in System Config, or via Menu, System info from any of the Config screens. The startup log will be at the end of System info output.

Kent

It's totally bog-standard - I've not customized it at all.  It's got an SD card full of flac files and a micro usb ->usb c adaptor into which is plugged an Apple usb c->3.5mm adaptor (the US one as the EU one has the volume cap).  I listen on IEMs (zero-2).  I sometimes use MALP (the android mpd client) but for the purposes of diagnosing this I'm using moOde exclusively.  I mostly power it using a battery (ie a powerbank) but also via a phone charger and the problem's occurred with both.

The key thing to look for is the buffer xrun message in /var/log/mpd/log.  The "crash" is when you get tens of those consecutively, one every ten seconds or so, and 100% cpu, for seconds/minutes at a time. 

Maybe occasionally clicking the progress bar to very near the end (20 seconds or so from the end) a few times? Especially the longer track. That's the best way to provoke it.   Also, maybe enable a few more PEQ filters;  this is a PEQ problem after all.   It doesn't always go wrong straight away (I didn't notice this problem for a while) but when it does it continues to happen.
