Comment 33 for bug 1040873

does the enter playback volume has and effect on the suboofer ?

there are only three DAC with volume control , the headphone will have to share the volume control in 5.1

the reason why you change the spdif out to speaker is just a hack to trick the driver to config 5.1 with the headphone playback volume control

do you mean model=auto

echo 0x16 0x99130111 > /sys/class/sound/hwC0D0/user_pin_configs

and dynamic reconfig is not enough for the driver to create the bass speaker playback volume using the new generic auto conf ?
