Largest total buffer in frames; 0 when the driver gives no bound.

channels_max

unsigned pulp::audio::PcmCapabilities::channels_max = 0

channels_min

unsigned pulp::audio::PcmCapabilities::channels_min = 0

period_max

unsigned long pulp::audio::PcmCapabilities::period_max = 0

period_min

unsigned long pulp::audio::PcmCapabilities::period_min = 0

Frames per callback the driver will accept.
