Error when compiling

When trying to compile, it throws this error. obs- no changes were made to the code.

Same here. I use following:

• IDE: Arduino IDE v2.1.1
• Boards library: esp32 by Espressif Systems v2.0.11
• Target board: NodeMCU-32S

regarding the config.alarm errors, those were a type problem:

- config.alarm_en = 1;
+ config.alarm_en = TIMER_ALARM_EN;
...
- config.auto_reload = 1;
+ config.auto_reload = TIMER_AUTORELOAD_EN;

But I couldn't solve much more. It seems that the i2s_write_bytes function is from an older library and it obsolete. But I can't seem to find which version.

If anyone has some clue, please, feel free to add to the topic

So I found in this issue from another repo: https://github.com/bitluni/DawnOfAV/issues/9#issuecomment-1114056322 that is a board version issue.

Downgrading to version 1.0.6 of the "esp32 by Espressif Systems" boards library solves the issue.

It would be nice though if we could upgrade the code to work with the latest version (currently at 2.0.11).
