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'. -- William Estrada MrUmunhum@popdial.com Mt-Umunhum-Wireless.net ( http://Mt-Umunhum-Wireless.net ) Ymessenger: MrUmunhum
