[GitHub] [incubator-nuttx] lucasssvaz opened a new pull request, #7360: esp32/i2s: Reduce MCLK multiple to support existing boards

lucasssvaz opened a new pull request, #7360:
URL: https://github.com/apache/incubator-nuttx/pull/7360

   ## Summary
   
   Using the current 384 multiplier to generate the MCLK of I2S might cause some high frequency noise on the audio playback of some existing boards. Reducing the multiplier to 256 fixes this issue.
   
   ## Impact
   
   The generated MCLK will be slower. For 44100 Hz, for example, the MCLK will be reduced from 16.9344 MHz to 11.2896 MHz.
   
   ## Testing
   
   Tested using an ESP32-LyraT board by running nxplayer and playing some audio files.
