Micro freezes audio [Solved]

(1/9) > >>

erviv:
I have had this problem in the past, more so with debian jessie.  With Stretch is was less apparent.  Now with Buster I have noticed more frequent audio freezes.  I moved my library and audio files to a USB connected external HDD connected directly to my rpi.  It previously was connected over the LAN to a different HD connected via USB to my router.  I noticed some apparent random micro-freezing and decided to move my files to the local HDD.  Have not noticed any appreciable difference.  I am running version 27.0.10. I would describe the freezes at about 1/4 to 1/2s.
My audio options are set as no decoding, and prebuffering is 10s, full file loaded not decoded into memory.
ex Source 48 khz 24 bit 2ch Internal 48khz 64bit 2ch (no idea about the 64bit)

Suggestions

bob:
Please test with memory playback disabled, thanks.

erviv:
Ok, with memory playback disabled the problem seems to be diminished.   I have still heard some micro-freezes, but they seem less frequent and shorter.   I will listen some more when I get a chance to ensure that the micro-freezes are not caused by some other activity on my pi. 
I had thought playback from memory was supposed to resolve this type of problem which was why I selected that option.
Thanks for the advice.

You can also fiddle with the buffering parameters in Audio Device Settings. Increasing them both may help.

I have increased them to 10 from 6, but can fiddle some more. This afternoon there was perhaps only one occurrence in about two hours of listening.
