[PROBLEM] CM5 + io board + internal Nvme = 10 second silences every 30 seconds

[georgescookie]

Hi guys

I have a weird issue where I have a compute module  5 in an io board and internal Nvme but get 10 second silence gaps every 30 seconds with every track! Unlistenable and annoying! 

Even with just a handful of tracks on the 2tb nvme, the issue persists. I have used crucial and transcend with the board btw. 

Putting the nvme in an enclosure works perfectly with the board, but I was hoping to use the internal slot on the io board to reduce clutter! Any help is appreciated. 
Cheers

That’s a bit bizarre.

I don’t have the same or even similar hardware arrangement to test so can only suggest the usual. Turn on moOde debug logging and verbose mpd logging and monitor their logs as well as the system log (journalctl).

By the way, you don’t say explicitly. Does this combo play Internet radio stations without drop outs? Tracks from USB drives?

The symptom suggests a hardware issue.

What make and model is the i-o board?

Hi Tim,

Sorry for the delay!

Here is some additional observations of the behaviour which I hope assists in troubleshooting:

• It is a CM5 4gb module and the official Compute Module 4 IO Board with Transcend 2tb NVME being used
  
• Takes 6 minutes for moode to boot up with an internal 2tb nvme installed (with the nvme removed and installed in a usb enclosure, it takes under 15 seconds)
  
• Takes 2 minutes shut to shut down with NVME, 10 seconds with no NVME
  
• With the internal nvme the overall navigation of moode is jerky i.e browsing menu, pausing and stopping a track (smooth as butter with no internal nvme or attached as usb enclosure)
  
• Takes 30 seconds for a FLAC/WAV to start playing
  
• A FLAC/WAV stops intermittently every 20 seconds, resumes after 20 seconds, this behaviour continues until the end of the track
  
• DSD was attempted but gave I up after 10 minutes of waiting for it to start
  
• An Mp3 takes 30 seconds to start and plays perfect all the way through
  
• Radio also plays perfect
  
• Nvme access light blinks 3 times just before it resumes play when its stops intermittently 
  
• When the FLAC/WAV is on repeat, after the 1st intermittent play, the track will play perfect on all subsequent repeats i.e  2nd,3rd, 4th play etc
  
• Going forward on a track on the playbar (time counter) will not play a section which was not been loaded/played before (i,e if the last 30 seconds was not previously played, that section will not play by moving the cursor forward), it needs to play/load first
  

I would also assume this behaviour applies to a normal Raspberry Pi with an internal NVME but could be wrong about that.

• Many thanks for your help

Hi Kent
Sorry for the delay, I would love to know how to do the debugging part and will try at the weekend to see if I can manage it.
To answer your other questions the internet radio plays just fine and with the same 2tb NVME used in a usb enclosure hooked up to the same set up also works perfectly fine.

The symptoms suggest some sort of odd hardware or board config issue. I have a Pi5 with a PCIe attached NVMe drive and no issues. The boot media is a uSD card. Other moode users boot off their NVMe drives and no issues.

You might want to try vanilla PiOS Lite and see if you still experience the super long boot times. If so then I'd suggest posting to the Raspberry Pi Forum or possibly the Pi Linux repo.

CM5 4gb module and the official Compute Module 4 IO Board -> are they fully compatible ?
