Hello everyone:
There is problem in the use of AIC3101 on the Leopardboard 365(http://designsomething.org/leopardboard/default.aspx ,AIC3104 has used in this board,but I replace it to AIC3101,and the CLKOUT1 was used when 27M crystal was used in DVEVM board,so I set the CLKOUT1 to output 24M,aslo the sysclk was chage to 24000000 in dvsdk/git/sound/soc/davinci/davinci-evm.c inorder to match this paltform).
When I use the decode to play the .g711 audio like davincieffect.g711,it's work perfect,but if I use the encode the get a test.g711 audio file,and then to play it,I cant hear anything but a litter noise at the begining.
./decode -s data/sounds/davincieffect.g711
Decode demo started.

----its works perfect,BCLK=256k WCLK=8k
./encode -s test.g711

----only some noise can be heared at the begin,BCLK=256k WCLK=8k,the MICBIAS output 0V
Is there anybody had used the AIC3101 in the linux-2.6.32-rc2-davinci,can you tell me the problem I had made,thanks!
