Is it possible to port Advanced Linux Sound Architecture (ALSA) to ESP32 ?
Posted: Sun Jul 15, 2018 8:45 pm
I was looking some Intel boards with xtensa DSP and found that Advanced Linux Sound Architecture (ALSA) and PortAudio http://www.portaudio.com/ works on these boards, here is the main page with more informations about ALSA for xtensa: https://www.alsa-project.org/main/index.php/Firmware
I tried to compile it using xtensa-esp32-elf instead xtensa-byt-elf and almost worked, the missing piece seems to be a HAL for ESP32 in the folder \sound-open-firmware\src\platform\ of [url]git://git.alsa-project.org/sound-open-firmware.git[/url] that maybe EspressIf already have somewhere...
My question is: is it theoretically possible, or there is some hardware/software limitation?
