Linux/TLV320AIC3106: Audio cape(TLV320AIC3106) not working on Beaglebone Black on Debian 9.3(4.9 kernel) but working on Debian 8.7

Hello,

I want to play audio on Beaglebone black so i am using audio cape with TLV320AIC3106 codec for the same.I am able to load BB-BONE-AUDI-02-00A0.dtbo on 8.7 Debian(4.4 kernel) on Beaglebone Black as shown below. This BB-BONE-AUDI-02-00A0.dtbo file comes by default in the lib/firmware folder. i dint do any modifications in the .dtbo file.

8.7 debian IoT( 4.4.54-ti-r93 kernel)::

aplay -l ---> no devices found

After changing uEnv.txt (cape_enable=bone_capemgr.enable_partno=BB-BONE-AUDI-02)

the logs show that BB-BONE-AUDI-02 overlay was loaded and i was also successfull in playing audio .i connected speaker as well so good quality sound is also coming

But when i tried enabling same audio cape on debian 9.3(4.9 kernel) using uboot-overlay method,its hanging while booting itself,not completing the booting.

i tried adding BB-UART1 as well using uboot-overlay,so boot logs tell uart1 got loaded properly.

I guess on 8.7 debian i loaded the overlay using bone_capemgr/slots method but on new kernel, we dont have an option of adding overlays to slots file instead we have to add it to uboot-overlay method.So for doing that any modifications required in BB-BONE-AUDI-02-00A0.dts file? If yes ,can anyone please share that dts file and also help me with the modifications to be done?   I have been stuck with this since a week,please help where am i going wrong.I couldnt find any support for loading audio cape on latest kernel. waiting for your response.
Thanks,
Jithu.
