Sound skipping on just one radio.

[CBx86]

Hey guys!

Using WebRadioDemo;
i try this online radio: http://5.135.220.118/320 The sound keeps skipping; i thought it might be the bitrate.
So I changed the bitrate to 128: http://5.135.220.118/128 And Keeps skipping.

Only with this one does this happen.
Try increase/decrease buffer, nothing.
I the board ESP32, CPU uses very low about 20% core 1.
VS1053 v4 using patch.

Some hint?

Many Thanks!

It's not really skipping, it looks like it's buffering, but it's not. It looks like something every 500ms.
Sorry for the not-so-precise explanation.

Many Thanks.

maybe chunked encoding?
Have you tried replacing HTTP/1.1 with HTTP/1.0 in the client.print command?

Hey! Thanks for answer.

The problem is not the glitches, the web radio plays (for 500ms), no sound (for 500ms), (and then plays again for 500ms) as if it were buffering. Or maybe it is..

In reading the issue. And try the RingBufferDemo.cpp.
Strangely, this radio gives a lot of 0 buffering.
Buffer: 0%Buffer: 0%Buffer: 0%Buffer: 0%Buffer: 0%Buffer: 0%Buffer: 6%Buffer: 0%Buffer: 0%Buffer: 0%Buffer: 0%Buffer: 0%Buffer: 0%Buffer: 0%Buffer:

Maybe even with strong radio signal, something is coming in slowly.

I will make a code to bench this.
This webradio needs: 124.72 Kbps average.
This ESP32 bench: 2759.45 Kbps.
It's not wonderful but it's ok.

Thanks!

Any other suggestions?

After a lot of thought and testing, increased the wifi speed a lot, buffers, etc, nothing worked. Decided to read the datasheet:

When i use http://5.135.220.118/128 works fine. I made some mistake in not being able to run at 128 in the beginning.

Many Thanks!
