i2s audio external dac - internal dac's GPIO25 & GPIO26 trigger on audio play so they cannot be used as

tomliekens commented 8 months ago

The problem

i2s audio is configured to use external DAC GPIO25 is configured as DAC to control a LED dimmer with stable variable voltage (inverted)

As soon as audio starts, the led's get triggered. at the end of the sound fragment the led's get triggered once again. It seems even though external audio dac is configured, ESPHOME triggers also the internal DAC when playing audio. And so both DAC's on GPIO25 and 26 cannot be used in projects with I2S audio and external audio DAC at the moment.

many thx if someone can fix this!

Seems like for now pins used for internal DAC are completely broken, not even with just external DAC (#4434). Can't find any solution to both issues
