"Server low mem" when playing AAC stream using S/PDIF.

[Ant-12]

As you know, S/PDIF output doesn't work on current firmware(V2.1 R2). The problem is in the presence of this file. The legacy build system based on GNU Make compiles every *.c file... I had to build the firmware by myself using esp32_win32_msys2_environment_and_toolchain-20181001 and esp-idf-v3.3.5. However, I encountered the problem of lack of RAM when playing AAC streams via S/PDIF output on Wrover-B. This happens when opening or updating the web interface page.

I can't test S/PDIF output. What is wrong and must be changed in the code?

What is wrong and must be changed in the code?

For what? To enable S/PDIF output you need to rename or remove the file specified above. This is because "\components\audio_renderer" folder now contains two files: "audio_renderer.c" and "audio_renderer1.c". Both of them are compiled but only last one is linked. Another way is to switch to CMake based build system. I don't have a solution for "Server low mem". Probably the webserver should use PSRAM instead of internal RAM.

sys.prerelease to test the pre 2.2R1 please.
