now i have GOOD (tested) CS-4235 based isapnp soundcard

works ok but sound are very very soft even when dac output is set to
maximum. speakers are connected to good port (SPK-out).

inputs.mic=0,0
inputs.mic.mute=off
inputs.cd=0,0
inputs.cd.mute=off
inputs.dac=255,255
inputs.dac.mute=off
record.record=0,0
record.record.source=mic
monitor.monitor=0
monitor.monitor.mute=on

is it ok to not have setting like output.master ? card is said to have
"hardware master volume control" 

it starts like that:
