[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,

I will report further when I’ve done so.

This just gets more and more confusing.  The 32-bit version, when I went to configure the audio hardware hadn’t auto-detected an I2S device.  Set it to I2S device, restarted, had to select the DAC+, wasn’t able to select Hardware volume, and changing software volume did nothing.  Switched off, installed the SD card with the 64-bit version, it saw the card, let me select hardware volume control and, yep, it plays, but the clicking is back.

I’m done with it for today.  I’ll try again tomorrow.
