| dac/volt_reg: improve performance (#7274) * dac/volt_reg: improve performance * modify dac to accept streams of any input rate to avoid resampling * modify dac to assume input voltage streams are constant by only grabbing the first input sample * modify volt_reg to output at the minimum sample rate * dac: Restructure the DAC sound devices a bit * centralize implementation based on lookup tables * add set_constant_vref() method for the common case where references are constant, thus avoiding the need for voltage regulator devices * convert williams.cpp to using this new method as a test |
