Default Music playback issues: quality/noise, stutter

Hi all,

I got my Hero on Monday and I'm blown away by this phone so far!

The only not-so-great aspect I have found is the music playback:

1) There is a small amount of background noise when playing music, which is noticeable
in a quiet environment during low-volume parts of tracks. I don't always listen to Metal on the subway, so this is kind of a problem.

2) Sometimes, when listening to consecutive tracks of an album, there is a stutter when a new track starts. Haven't found a way to reproduce this reliably yet.

I was expecting to be able to ditch my iPod for the Hero, but I'm a little hesitant now. Does anyone else experience these issues?

I have the same issue with the jumping at the beginning of a new track, haven't noticed the background noise though probably because I do listen to metal.
Maybe it has something to do with standard sd card or how the mp3 was created? I hope someone knows the answer.

Also:
Does anyone know if there is a graphic equaliser somewhere? Music seams to be too trebley (using Seinnhauser earphones), but I haven't been able to find anyway to adjust it

Forgot to mention: I used 192 kbit/s MP3s encoded by iTunes and portable AKG headphones. I'm going to try out the included earbuds when I get home, to see if they "equalize" anthing.

I'm listening to Rufus Wainwright's Hallejuah on my Hero now over a set of Sony MDR-NC22 Noise Cancelling Earphones (in-ear type) with the noise cancelling switched off. No background hiss. Could it be from your MP3?

That's possible of course, but I never noticed noise like this on my iPod. One other thing I'll try at home is listening to a WAV file and check for noise.

Send me the MP3 file and I'll load it up on my device now and let you know if I'm having any problems

Ok, I tried the included earbuds, and the noise is much less pronounced than with my AKG headphones, but still audible. It starts as soon as the playback begins and stops about 2 seconds after I pause the music player. (I guess this is when the audio hardware shuts down.)

MP3 and WAV exhibit the same noise, so it's not encoding artefacts.

Is it a buzzing noise?

I'd describe it more like a hissing sound.

Edit: I have attached a sample MP3 (hissingat5.mp3) in a ZIP file. I can clearly hear a hissing sound around 0:05 when the music gets quiet and I'm not using the included earphones. Anyone else? (I've checked the original CD with the same headphones, there's definitely no noise on the recording.)
