Solved: No Sound for certain files/streams
#1
I just installed moode on a Raspberry Pi B3+. I updated it and it run now version 7.2.1.

The box is connected through the box jack output to an amplifier.

Most files or streams does not produce any sound while some other do:

- some streamed radio works fine (FIP for instance) while most does not produce any sound
- almost no file produce any sound
- the test file produce sound normally

In all case everything seems normal at the interface level : its hows that the track or radio is playing correctly, volume is high, just no sound is output!

If someone could give me an idea on where to look that would be nice.

Here are the results of some commands which may be useful:

Code:

I just found a workaround:
  • I switch the Configure > System > Kernel architecture from 64 bits (experimental) to 32 bits,
  • restart the system.
Everything seems to work nicely now.

I have similar problem. However I run it on RPi2 using 32-bits kernel.
Here is a similar thread where I added my comment with the issue description:
