Re: Module ESP32-2432S integrated with Annex
It is done. There's nothing like soldering and desoldering SMD resistors on a rainy afternoon.
I have left some huge blobs of solder, but I have verified that there are now these values: 46.7 ohms between C11 and C12 and 21.8 ohms between C10 and R9. Tonight I will continue.

I flashed the new 1.51.7 version, and I installed the 47K resistor for R7.
PLAY.SPEAK and PLAY.MPG sound OK, but PLAY.WAV seems to play the sound too fast.

Thant for the report, I never more used the wav since I implemented in the code, some years ago .[Local Link Removed for Guests] wrote: [Local Link Removed for Guests]Fri Dec 15, 2023 11:31 pm I flashed the new 1.51.7 version, and I installed the 47K resistor for R7.

I remember that this kind of bug was raised some time ago on the SDK GitHub, probably it is caused by an update of the I2s driver.
Ok, I'll have a look.

I cannot reproduce the problem you mention, I converted an mp3 to wav (from 4mb to 43mb ) and it plays like the original.[Local Link Removed for Guests] wrote: [Local Link Removed for Guests]Fri Dec 15, 2023 11:31 pm I flashed the new 1.51.7 version, and I installed the 47K resistor for R7.

Can you upload a file to demonstrate the issue ?

Re: Module ESP32-2432S integrated with Annex
Could the problem be that resistor R9 also has the wrong value?
In the schematic and on my board, it appears as 68k ohms and in all the datasheets I can find it says that it should be 20k, the same value that R8 should have.
In one of the datasheets, in English, it details how to calculate both to adjust the profit. See BRIDGE CONFIGURATION EXPLANATION and ri/rf resistors. In our case, R8/R9.

Re: Module ESP32-2432S integrated with Annex
I was just playing some wav files of animal sounds. They play OK with Annex32 version 1.48.22 .
Samples attached. They're not really jpg files. I just added that extension to get the wav files to upload.

Re: Module ESP32-2432S integrated with Annex
I don't see the files, so I guess I don't know how to upload them.

Here is another try adding a false pdf extension.

Re: Module ESP32-2432S integrated with Annex
Thanks, I'll investigate in the future.
I tested and it works with an I2S dac on the ESP32-S3.
It works worrectly if converted to 22050 Kbps (your are at 11025).
I think that this is a regression on the I2S driver.
Will be fixed but with low priority
edit :
fixed, it will be in next release

Re: Module ESP32-2432S integrated with Annex
Fernando is right,
R8 and R9 is 22 kOhm,
R7 is 47 kOhm an the tone is better now.
