Debugfs file asoc/ipaq/uda.../dapm/Playback shows:
Playback: On in 1 out 1
stream Playback active
out "static" "DAC"
out "static" "DAC"
out "static" "DAC"
and file DAC shows:
DAC: On in 3 out 4 - R2(0x2) bit 10
stream Playback inactive
in "static" "Playback"
in "static" "Playback"
in "static" "Playback"
out "DAC" "Output Mux"
out "static" "Analog Mixer"
is it correct? Shouldn't stream Playback in DAC show active status?
Also I noticed that alsamixer works slower when playing music so
some data must be sent to codec but I don't know is that music
data or sth else.
