Sorry I misunderstood. The value that is passed in min and max is in dB. For min and max values, it's a static dB value that I return. But when the volume adjustments need to be done, based on the value given by ALSA, I set the sound card registers to reflect that dB value. When volume is queried for, I read the specific sound card register and return the dB value to ALSA. Will this implementation be ok?
