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

[georgescookie]

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
