[PROBLEM] Popping sound during playback

[manolomalele]

Here's the fix.

 

Excellent!
How do I apply this fix?


Another question @Tim Curtis:
Wanting to get rid of the clicks/pops, what if I use spdif/optical hat to take the signal from the berry to the usb dac?
Will this solve the problem? Doing this way there will not be any usb-uac connection and, therefore, no uac issue...

What do you think about this solution?

In my case resampling was on because I had a I2S Allo with reclocker which will not work without resampling. With resampling Disabled most of clicks and pops dissapeard. However even with disabled resampling a few pops/clicks will randomly appear.

Hope will help someone who has same issuse and maybe for further debug.

Hi @codiac
I have the same exact Issue.
Only playing DSD natively, with no resampling I can perfectly hear pops/clicks randomly.
No problems playing flacs or mp3s.
Pib3+ connected straightly to a topping d50 via USB.

Same what you said with volumio: quite no clicks at all. Just one or two per song.

I'm trying to buy a hat with spdif and coax out so I could connect the dac avoiding the usb port...

From your system info dump:

Code:

Architecture            = aarch64 (64-bit)

What happens if you revert to the default 32-bit kernel?

I'm not sure I understand your statement

Same what you said with volumio: quite no clicks at all. Just one or two per song.

Does "[J]ust one or two per song" mean you still get clicks, just not as many?

Hi Kent,
Yes exactly what I tried to say.
Same everything but the sdcard:
Dsd with moode lots of clicks and pops
Flac or mp3 none.
Dsd with volumio (same songs) just a couple during the playback. 
Flac or mp3 none. 

Sorry for not being as clear as I would be

@manolomalele

That would suggest to me that the issue originates in code shared by the two players---including the kernel, drivers, etc.---with the effect being more or less prominent depending on specific versions of various packages. 

Sorry, I don't have the issue here so don't have any way to investigate it.

I have never played dsd. What file format is the dsd. I would try to see if I get pops on volumio and let you know. Any particular song?

Hi,

here --> http://www.2l.no/hires/

you can find free download files.

DSD it's a kind of Hi Res format ---> https://en.wikipedia.org/wiki/Direct_Stream_Digital

On the moode page go...m>Configure>System>System Modifications>Kernel architecture        and select 32-bit and SET then reboot.
