ProtoDAC TDA1387 X8 project

[Tim Curtis]

One test to try is to put some tracks in the Queue, start the first track playing and then let MPD automatically transition to each subsequent track. AFAIK MPD keeps the audio output open continuously under these circumstances and there should not be any glitches.

Tim - I did try your  queuing suggestion for which thanks . . . but I'm still get a varying selection of clicks occurring  (some pronounced, others quieter) across the queue listing, but not in any noticeable pattern

Mark - new module purchased and installed - still getting the  fairly frequently occurring click on track start  either (i) as per Tim's queuing suggestion above, or  (ii) playing tracks straight from an album.  Continuation of the issue with new module tends to suggests the module is not the cause.  Anything else on the DAC board - component-wise -  I should be looking at or testing?

Let me know

Best, Simon P

No problem with the DAC board other than the module. Maybe something in the component chain. For example, a very sensitive preamp? Try software volume or CamillaDSP volume control and go directly to the power amp.

Mark - re Camilla DSP, under File Management I have V2-ProtoDac selected from the dropdown menu - correct ??- but at the top of the Configuration page under Signal Processing, the drop down menu is not showing/open for me.  Am I missing something obvious?

Separately, is a dry solder joint on the module a possible explanantion?

With Camilla the config is selected in the "Signal processing" dropdown on the CamillaDSP Config screen. Then SAVE.

You can also set this to "Off" and instead turn on ALSA Polarity Inversion. This setting is in the MPD section on the Audio Config screen.

For troubleshooting though I would leave both CamillaDSP and ALSA Polarity Inversion set to Off.

Also,
1. Do you get any glitches during Radio Station playback?
2. What model Raspberry Pi?
