The VU meter displays even without sound

Hello Schreibfaul1!

I use your I2S audio library and have integrated it into my own version of yoRadio.
Version 3.4.3ze Updated on: 27.11.2025

Thanks for all the work you put into it!

I get a lot of feedback and I myself experience that the VU meter shows a floating display at 75% of the display range between played files when there is silence.

In the old version (Version 2.0.5k * Updated on: Aug 23.2022 this phenomenon was not experienced.

Is there a solution for this?

Hi @VaraiTamas,

YoRadio is a great project.
A lot has changed since August. You say that the level stays at the last level and doesn't go back to zero when the song is interrupted. I think that can easily be improved.

Hello Schreibfaul1!

At the end of the mp3 file playback, the music stops and both channels of the VU display start to float at the same level. The eof has not yet arrived in the audio_info_callback , so I can't handle the problem.
Do you have any suggestions for this?

Wolle, same story take palce when you suddenly loose wifi. VU meter value will not back to zero. Looks like Audio task is doing sth. in background.

I hope this is no longer the case with version V3.4.4.
