Hi
I got my first diamond a few months back and within a few weeks during listening to mp3 files the bass would drop out of the music and it would become very tinny.
Tried to solve the problem my-self checking the usual's like headphones, audio booster, mp3 quality, different audio players and finally a reset which solved the problem for a few days but then came back.
My provider is orange uk and i contacted them about it, after two weeks! they couldn't come up with a solution and sent me a new phone.
Now after having my replacement phone a few weeks it has happened again and also seems to affect call audio quality when using the headphones. I can't tell if it's affecting the speakers as they are of low quality anyway.
Orange support is woefully poor and htc can't help as it's an orange branded phone.
I am wondering if anyone else has had similar issues / solutions and if this is a generic problem with the diamond?
thanks

Just had the same happen with my TMob Compact IV this morning.
It is being replaced as faulty on Monday but is this a worrying sign of dodgy hardware build?
