Okay, so my phone's back from the service centre, and the report reads "HW part dirty". At first I was quite doubtful that they managed to fix the hissing noise by just cleaning whichever phone parts were supposedly dirty, but after testing the phone, I can hardly notice the hissing noise anymore. It's been almost eliminated. There is still a VERY faint noise, but it's not distracting as it was before. I'm satisfied with the result (except that now my phone creaks because they've opened it!)
Also, I got a reply from SE Support UK:

Thank you for contacting the Sony Ericsson Call Centre.
With regards to your enquiry, this is not a firm ware related issue on the hand set, it would seem that there is an issue with the walk man feature on the hand set and we would advise you to have the hand set looked by one of our engineers.
Should you require any further assistance, please do not hesitate to contact us again for further help and support.

glad to hear your phone is back kristianm and they have eliminated the hissing, but i am not tempted to update the firmware still, coz it wont read m4a tags, some ppl reporting bluetooth speeds become slow, i am still sticking with R1N (all working fine), i really got no other issues, and SE online support hasnt replied its been a week or so, anyways i had enough of mailin SE and i am off to doin my work and forget abt the hissing issue for some time. and i think ppl are not worried more abt this issue as now many are goin to upgrade their phones soon. anyways bye bye i am goin on a 2 month vacation (even though i rarely post), take care all..

Dear JP,
Thank you for contacting the Sony Ericsson Call Centre.
With regards to your enquiry, we have escalated further the issue regarding the m4a tags and we will contact you again about that as soon as we have more information.
Regarding the hissing and static noise, we do not see this as a bug and for the majority of customers is of such a negligble level that it has not been seen as a problem. However we will make a note of it for future development.
Regarding the Bluetooth problems, we are not aware of any issue caused by upgrading to the new firmware. We would advise these customers to contact us so that we could investigate the problems they are having.
Should you require any further assistance, please do not hesitate to contact us again for further help and support.

hey Mark_Q,
What do those figures mean? I am totally ignorant of it. Are the figures higher the better? Or the other way round?

bbjuju,
So you have no experience with hifi/stereo equipment? OK. Let's put it simply:
In Signal to Noise Ratio the audible distance between background noise level and sound level. The higher the Decibel value, the better the performance.
Harmonic Distortion goes opposite, lower value better.
As the Output Voltage is high you'll hear the music more loudly and there is no need to push the playback volume to maximum, which again cause more distortion compared to moderate level with same player.

The hissing noise is back!!!
After I readjusted the equalizer, the hissing noise is back! Then I tried putting it back to "Normal", but the noise is still there!

My email to SE Sweden:
Quote:
A VERY serious issue/problem on W800i that has been present since firmware revision R1N035 and is yet to be addressed:
Walkman player hissing noise
An audible hissing noise is heard as soon as the Walkman player application is started, regardless whether a song is being played or not.
Also, this audible hissing noise gets louder when a soft song is being played. (Set the volume halfway or less to make the hissing more apparent.)
I'm not the only one experiencing this problem, but other W800 users as well. Please, do give time to check this thread over ESATO, a Sony Ericsson fan site:
http://www.esato.com/board/viewtopic.php?topic=118023
What worries me is the fact that on several instances Sony Ericsson Customer Support denies or won't confirm that this problem is firmware-related (my emails to your Customer Support in the Philippines and UK). I'm from the Philippines, but I'm getting desperate to voice out this problem and make it known to you, and so I'm emailing Sweden, hoping it would reach those who are really developing the firmware for the phone.
Everytime I email SE reporting this problem, I always get the response to have the phone checked by an authorized service centre. I already did it just yesterday, and they said they already did everything they can to get rid of the hissing noise (phone refresh, firmware update to R1BC002, ec.) but after receiving the phone the hissing noise of the Walkman player application is still there.
And I'm also eliminating the possibility that my phone could be an isolated case, that it's from a bad batch of W800, since other W800 users are experiencing the same problem as well.
It's just very disappointing that the first phone to carry the Walkman brand has this hissing noise, destroying the excellent music quality it once delivered when I still had R1L002 on my phone. Even a K750 now sounds better than a W800.
I love my W800 and I still trust Sony Ericsson, so I'm not giving up hope that you would look into this problem.
Thank you very much.
And the response I got just now:

We have now received an answer and this will not be fixed for the W800i since this is an issue regarding an earlier update to prevent digital distortion.

Dear Customer,
Thank you for contacting Sony Ericsson Call Center.
We have now received an answer and this will not be fixed in Sony Ericsson W800i.
The noise in the background is because an earlier update which included a fix for digital distortion.

So I guess the only way to get the hissing under control would be to go back to an earlier firmware.

Isn't it ironic?
Here they have a fix that takes care of "digital distortion" but introduces hissing noise. In the end you still end up with bad (or much worse) quality music playback.
