[PROBLEM] Audio Glitches

[awrc68]

@awrc68

In a quick test using moOde 8.2.2 on a Pi3A I can't repro your start/end glitch with either the Pi Headphone Jack -> wired headphones or a Creative Tech BT-W2 USB adapter -> Sennheiser wireless headset.

Somewhere I have HiFiBerry DAC+ and DAC+ Pro cards in a moving box---they are similar to the IQAudiO DAC+ (but don't have a headphone jack)---but rather that dig for them I'll wait to see if Tim can repro with his DAC.

The 'Rage In Eden' FLAC files pass the flac -t test, play without issue on my system, and the metadata look good.

I’ve done a little more prodding and established that I’m getting the clicks at the beginning and end of even the stereo test file - and that they’re all playing without said clicks if I hook the headphones up to the Pi headphone Jack.

I found a couple of references via Google search that point the finger at the 5122 - including one person who was having this exact problem until he went into alsamixer and changed the left and right auto-mute time from 21ms to 2s or so.  

Of course, when I did that (the auto mute times were set that low) not only did it not fix the problem, it caused /boot/config.txt to disappear.  So I’ve reflashed the SD card, this time to the 32-bit version, and I’m going to see how it plays if I leave the config.txt completely alone - it can live without the fan for now while I test it.

Cheers,

Al
I will report further when I’ve done so.
