Unhappy Atrix HD audio problem

I have been using Atrix HD MB886 -unlocked- in India for nearly an year now

But Since CM11 M7 build - i have been facing wierd battery drain and problems with Audio(earpiece,speaker and headset)

I then flashed factory image

MB886_att-user-4.1.1-9.8.0Q-97_MB886
and also got updated to
98.4.20.MB886.ATT.en.US (latest OTA)

But the audio problem is still there

Ever since, the speaker sound and all the system sounds, including ringtones, call volume, etc go off by themselves randomly, so I can't hear anything when the phone rings, If by chance I pick up a call while in this state, I can't hear a word the person on the other side utters, but that person does hear me clearly.

Restarting the phone,the sound works perfectly, until for some unknown reason it goes off, and I have to repeat the whole process.

Reading through forums on the web, some people who have had the same problems report improvements and some very few even report having obtained solution to this persisting issue after installing the app "SoundAbout" from google play store. But no use for me.

I have tried nearly all ROMS for Atrix by now - but no relief.

Any fixes., ????!!!!!
