Ok, couple of things.

I'll take it when you press the buttons (+/-) you see a green bar on the screen with the words "Media Volume" above it?


1 - while playing the music keep pressing the - until the volume is as low as it gets.
Listen to the volume. Then take the volume to the max. Are you sure there is no change? It can be hard to detect the changes.

2 - in the settings / sound & display check the Media volume is set to.

3 - Do you have an app like "Volume lock" running?

 

Ok, the headphones are even more "sensitive" to not seeming to change volume.

I too have just recently started using the phone as an MP3 player. Changing the volume while listening to some songs it takes a lot of movement before I can hear any change.

Refere still to point 1 of my other post.

 

I've just developed exactly the same problem.

Media Volume bar changes, but headphone volume doesn't. I also have two other problems that may be related to this.

1-All call are answered on speaker phone, probably related to point 2
2-The phone often thinks it's in a car mode. I have 'disabled' this although I think all I'm doing is masking the problem. This problem possibly manifests itself through a short on the USB connectors that make the phone think it's in car mode. This problem may be getting worse (i.e. the short is more permanent now and the headphone volume being the end result)

I will keep you posted.

 

Hi, I have noticed the exact same two problems from quite some time now...

1. Volume green bar goes up down and to mute but audio video volume does NOT change with it. Volume bar is controlling ringer volume fine.
2. Phone is always in car mode ... speaker is on permanent...
I have recently started using a navitech docking charger for my htc desire as i had lot of problem with the wired head of its original charger. I have noted that everytime i put on the phone on the docking station for charging it turns on to 'CAR mode enabled' mode...

please help... any solutions...
