Found a little help. Try setting the limit for audio over headset from volume bar> 3dot> settings icon> 3 dot > set audio limit and fix one value which you use. Done try playing the music at lesser volm than the limit. Please don't expect it to do wonders. It doesnt help much but patch updates are a little far now. I didn't find it out someone on YouTube found it out. Well share with other m01 users if you have time. Thanks.
