White noise

[FatherMarco1971]

Using release 3.1.0 there is a strong white noise that start as soon Audio.setPinout is called.
Everithing work fine using 3.0.12 so ithink is a sort of bug introduced after 3.012 release.

Anybody with similar problem?

Found the cause.
The problem is due to the line:

m_i2s_std_cfg.clk_cfg.mclk_multiple = I2S_MCLK_MULTIPLE_128;

That was modified in:

m_i2s_std_cfg.clk_cfg.mclk_multiple = I2S_MCLK_MULTIPLE_512;

I'm using a ESP32-Audio-kit by ai-thinker swith ES3288.

Have you any idea why this cause the issue and how to solve without branch the library?

Hello FatherMarco,
I can't say anything about the ES3288, I assume that it has an MCLK pin. Most DACs get the clock from BCLK and it doesn't matter what value i2s_std_cfg.clk_cfg.mclk_multiple has. I think the value has been 512 for a long time, now it is I2S_MCLK_MULTIPLE_128
