What is the value of front playback volume in alsamixer? 

There is no headphone playback volume, gree lineout and headphone jack
have to share volume control since the other two audio outputs are used
for surround, center/clfe

It is strange that dB range is 115 as dB of audio outputs are -64 to 0
dB


} control.2 { iface MIXER name 'Front Playback Volume' value.0 64 value.1 64 comment { access 'read write' type INTEGER count 2 range '0 - 64' dbmin -6400 dbmax 0 dbvalue.0 0 dbvalue.1 0 } }
