Hi group,
I have found the documentation about ALSA very confusing. Where can I find the definitions about the fields in the structure_snd_pcm? Specifically Buffer, Rate, Period, Buffer Size, Period size, etc. Basically all of these:
Device: 8c297b8 PCM Device name = 'default' PCM state = RUNNING access type = MMAP_NONINTERLEAV format = 'U8' (Unsigned 8 bit) subformat = 'STD' (Standard) channels = 1 rate = 8000 bps period time = 10000 us period size = 80 frame buffer time = 0 us buffer size = 65536 frames periods/buffer = 0 frames exact rate = 8000/1 bps significant bits = 8000 is batch = 0 is block transfer = 1 is double = 0 is half duplex = 0 is joint duplex = 0 can overrange = 0 can mmap = 1 can pause = 0 can resume = 1 can sync start = 1
My program is not honoring the 'packet size'.
