The PA gain can be set in steps of 1.5 dB from -3 dB to 18 dB, that is, in 15 levels. Fix the dB values for the PA volume control as experiments using wsa8835 show that the first 16 levels all map to the same lowest gain while the last three map to the highest gain. These values specifically need to be correct for the sound server to provide proper volume control. Note that level 0 (-3 dB) does not mute the PA so the mute flag should also not be set.
