On reflection - I just mucked around with lower volumes. Those who don't like to send themselves deaf and are sensible enough to play their music at low volume probably will benefit from AKTD's files. But, if you want to play full volume be prepared to get distortion. It all comes down to compromises and choosing what best suits your needs. I still say well done to AKTD for biting the bullet and trying to solve this issue.

We'll I've bit the bullet now it seems lol...here you go no distortion and no hissing files I think at least...just done 2 mins of testing...these are the last files I'll be releasing for the next month....please replace all drivers. Enjoy.

PS: this will work only with R1BC settings.xml.....I've tested with bass levels upto 12 from the give 8 in the settings.xml file and no distortion. Volume must be at 10.

Bugger! I wanted to go to bed. I am going after this. I Just tried your last bunch of files. Heaps better!!! To be honest I found it much harder to tell the difference between the 2. Even the Mega Bass seems the same (even R1BC will distort on some mp3's with a heavy bass beat). I could still hear hissing/static though at full volume during silence. But at lower volumes I do think the hissing is better.

Just went through the revision history of the drivers......theres been no change in any of the music drivers since R1N firmware....sony have'nt even tried to solve the hissing problem.....the only difference has been in the earpiece at VHF and UHF between the R1N-R1AAand R1BC.....I would really appreciate it if someone gave me the R1Ca acoustic drivers.
Theres abit of hissing in the above drivers...just tested them out...will try to release an updated driver within the next 5-10 mins...damn I got to go study lol got an exam in the morning.LOL
I'm trying to isolate the file that causes the hissing previously I thought it was the farfield_play file.....now so sure now though.....maybe the Handset_play or DSS_play or the Lo_play my berts on the handset_play
Damn I'm unable to make out the difference between no noise and noise now.....anyways heres 2 more drivers to replace think its the handset_play

Edit: Right this combo is working best.....less noise and bass cracks up only slightly at highest volume.....looks like we beat SE....anybody think the noise in this version is too much....I got the Hex editing tools and with some help from you chaps we can re-write the source code in Hex format...very tiresome but its been done with the motos.

sorry i never backed up my files so i cant get them for you. the first fix you posted works wonders. i wouldnt be mad enough to keep original updated firmware unless i plan on becoming deaf by the setting the volume to full(hiss still very present) and being unable to listen to any classical or piano pieces cause of annoying hissing.
hiss is reducted dramaticly and is no longer a problem. quality is all that counts to me
if you want to set the volume to FULL then set eqaulizer to voice.

@ mongoose3800
How can you judge sound quality when you set the eq to full on everything? I've tested this with 4 different earphones. Sound quality is never good that way
@tupaq1
You're right. The first files works wonders!
If someone tests the audiodrivers:
Please use good earphones. (Something like the Sony EX-71)
Please set the eq to match the best sound quality, not to higher the volume
Please DON'T use Megabass: If you have to use it, look for other earphones! (IMO)
Please do always use the same songs to test the sound quality.
@ aksd
The "no noise" files produced the hissing again, so i reverted to the fisrt set.
I'll give the third set a go now ...
Ill be back

Tested and... IT WORKED!!! just as good it was on R1L002. Of course there is still a hiss, because it had always been there, but is almost unoticiable, unlikely it was with R1BC002. GREAT WORK! Know it is perfect, excellent video and audio quality

paternoster:- I can understand your point. The only reason I pump the equalizer right up is to get the volume as loud as I can get it. I also like to hear all the frequencies I can. I can see why it may not be to the liking of some. But, I find with the equalizer set to full that the sound is fine and it doesn't distort on the orig R1BC drivers. I quite often tone down the treble though. I think the eq manually set to full is better than the Mega Bass. Mega Bass just sounds horrible sometimes. It's all personal preference. It could also be my aging ears that have been punished with a fair bit of loud music. The one thing the full setting will do is show up distortion or amplification issues. This is why I noticed the distortion in some of the earlier no-hiss files.
AKSD:- I plan to do some more testing of your stuff today and will also concentrate on the hissing/static at low volumes. I've never really been one to play at low volumes - but now that I have finally picked up on the noise that people are referring to at low volumes I will be able to pick the difference.

I tried the second and third fix, but it seems to make the hiss come back so I decided to revert back to the first fix! Anyways, thanks for the great contribution to SE users! =]
~Edit, can anyone also post R1BC settings.xml? Thanks! Btw, if I add these settings, I'll still be able to update via SEUS right? Thanks.
