If line_ in is used as input, setting the gain to 0 is correct.

The man is right. His error description is correct, and it needs to be fixed.
Please reopen this issue as it is valid and prudent
As @TAMHAN suggested, reopen it.

Hi, Thanks to @jujax 's exmple project I got my Lyrat 4.3 board working as well. The only issue in my case is extremely low volume at the paired bluetooth speaker. I spend hours looking for solutions with no luck at all. Would be great if someone can provide me some hint to fix it. Any suggestion is highly appreicated.
Hello,
I try to use my ESP32-LyraT 4.3 to send sound to Bluetooth headset from line input. Actualy ESP-ADF library enable line input only when sound card is initialized with :
with this mode, sound is redirected only to speakers or line output. Pipeline doesn't send sound to writer streams.
To bypass this limitation I use directly ES8388 driver library with this function located in
es8388.h
:By the way, sound is really dirty without setting PGA gain to 0db :
It works very well with these modifications, and I create a github deposit to make an example. Maybe I disrespect some coding and github conventions (bad licensing for code, bad README.md), every improvements are welcome. And sorry for my english.
