fun fact - but directly pasting this log {just 29 kb} to gmail's mobile web mail interface resulted in page reload...

so i copypasted it via pre-installed wps office. 

most suspecting imo

audio_output_ptr = {0xf66050a0, 0xf66050d0, 0x0 <repeats 30 times>

but may be those just pointers on one for each channel, so 0x0 is normal for unused channels
