- directly write i2s from sync task
o use DMA events to ensure buffer is empty on hard sync
- add i2s playback task
o try synced playback using i2s DMA events and task notifications
- drop short latency buffers
- drop ADF pipeline stuff related to playback, this introduced too much non deterministic delay
- add fast median calculation component
- increase LWIP buffers
- try to improve synced playback using APLL adjustments
- reduce diffBuf size to 1, bigger values seem to be problematic if packet loss is happening, maybe we need to detect this and clear diffBuf
- do early time syncs on boot to fill diffBuf
- playing with pipline ringbuf sizes and I2S DMA buffer sizes
- use espressif ADF, remove external opus rep
o uses audio pipelines now
- change code to use flac decoder
- remove mersus code
- add first try of audio synchronization
o needed to sync timeofday to server on reception of server settings to avoid overflows in timeval calculations (int32_t on esp32 SDK)
o still a lot of TODO's in the code, but it's almost in sync, although there is quite some chunk skipping which I am currently working on
