Subject: ASoC: ABE: disable 16bits support on MM_UL path
X-Git-Tag: ti-ubuntu-3.1-1282.10~1
X-Git-Url: http://dev.omapzoom.org/?p=integration%2Fkernel-ubuntu.git;a=commitdiff_plain;h=8b5836d9539d23c4876a68e155a967a0b8a98c7e
ASoC: ABE: disable 16bits support on MM_UL path
16 bits support is broken on MM_UL path, resulting in
a noisy channel on stereo record.
This work-around disables 16bits support (32bits remains).
If required, the format conversion shall be handled by SW layers (alsa).
Another alternative is to use MM_UL2 path (that properly supports 16bits).
Example how to setup and test MM_UL2:
amixer cset name='MUX_UL10' 11
amixer cset name='MUX_UL11' 12
arecord -v -D plughw:0,1 -d 5 -f S16_LE -c 2 -r 48000 record.wav
