Default Kindle fire speaker not work with any custom ROM

Hello everyone,

My kindle fire's (1st gen) speaker is working properly with stock ROM 6.3.2 and modded ROM 6.3.2 with playstore, but when I install a custom ROM ( CM9, CM10 and latest CM11 ) everything is perfect except speaker not working at all ( but headphone is OK ). It back to work when I re-install stock ROM !

Does anybody have the same issue and are there any solution? Thanks
