This would suggest it is not caused by sample rate changes.

It’s hard to say, since they knocked off Allo’s card, is it truly
compatible with the driver.  What is the audio source?

I put 48000 for max sample rate and vLX as the resample setting - no
effect on the popping behavior.

That would most like be caused by lack of hardware mute when the DAC
makes a sample rate change.   Thats up to the driver to handle with the
hardware.  Force everything to be resampled to one rate will avoid the
issue…
Or at least prove that is really the issue.

[SlimDevices: Plugins] PiCorePlayer with DAC - popping noise prompted by track change / silence

2021-06-11 Thread rgthorpe2001


Hardware is Raspberry Pi 3 Model A Plus Rev 1.0 with an Innomaker HiFi
DAC Hat (PCM 5122), playing though the hat's headphone jack.  Software
is a fresh install of 7.0.0, selecting Allo Bass DAC per Innomaker's
instructions (the issue isn't new to 7.0.0, however, had it with the
prior pCP version as well).

The player produces a slight popping sound before and after certain
silences.  The most common case is when advancing to a new track if the
prior track ends in silence - there will be a small pop with two seconds
or so left in the track, then another pop right with the start of the
new track.  There is no noticeable popping, however, when there isn't a
silence at the end of the track (e.g., classical movement broken among
multiple tracks).  Occasionally a deep silence in the middle of a track
will also provoke the pops.

I have tried adjusting the buffer settings, without it affecting the
pops.  Are there any other settings on either the Squeezelite tab or the
audio card tab in pCP that others have had success with in fixing this
kind of issue?
