Comment 29 for bug 893402

Last night I tried to enable playback on plughw:0,0 in linaro 12.01 (3.1.1-8-linaro-lt-omap):

amixer cset name='DL1 Mixer Multimedia' 1
amixer cset name='DL1 Media Playback Volume' 118
amixer cset name='Sidetone Mixer Playback' 1
amixer cset name='SDT DL Volume' 120
amixer cset name='DL1 PDM Switch' 1
amixer sset 'Headset Left Playback' 'HS DAC'
amixer sset 'Headset Right Playback' 'HS DAC'
amixer sset Headset 100

aplay -D plughw:0,0 test1.wav -v
==========================================
and I got crash in kernel:
