Micro freezes audio [Solved]

<< < (9/9)

erviv:
So I investigated using volumio as a renderer on my Pi with JRiver on my second Pi asa server. While i didn’t notice any microfreezes I did have a very infrequent audio stutter. Also with volumio as a renderer, or perhaps any renderer, volume only seems controllable from the client ( as opposed to from JRiver or JRemote.
I like the simpler interface with JRiver.  I will see what happens when I replace the power supplies sometime in the next few months.
Meanwhile the microfreezes are infrequent enough that for my purposes I will stay with my original set up.
Thanks again.

Funnily enough one of the items I never considered, but was a common denominator between my two pi's, was the SD card.  This week I ran the raspberry pi diagnostics tool against both pi's. Both SD cards failed the test, specifically on writing speed. They were both the same name brand SD cards.  Read speed passed although not by a lot. Writing failed miserably.
I purchased two new SD cards of a different brand. I reloaded raspbian on the pi's and ran the diagnostics again. Both new cards passed with flying colours. I re-installed JRiver without a glitch.
I initially used the new card on my new rpi4 and had no issues.  I played music the full day and no sound freezes.  So I thought to try the same make on my rpi3 and have not yet heard any micro freezes.
Interesting. So I thought I would post the results here in case others experience a similar issue.

By default, MC writes to the disk to buffer incoming audio so that would explain your result.
You can disable that behavior, with a possible small loss in functionality (seeking on certain streams), by checking the "disable audio buffer to disk" under MC's Media Network options.

erviv:
Bob, does that apply only to audio being played over a network (media server) or does MC write to the buffer when playing standalone? I ask because the suggestion is to disable buffer to disk under Options/Media Network.

Thanks for identifying the “why”.

JimH:
That's a network setting.
