I am using the R4EK001 firmware (R4EK001 main file + R4EA031 FS, to be precise) and the rufinus’ v3 acoustic driver. Problem almost solved (very acceptable level) for the walkman. Radio “morse code” effect corrected, but some crackling when starting the radio.

I have two MS cards, 512Mb (sony) and 2Gb (sandisk). I will test your theory using phone memory.
About the crackling problem…
I’ve tried every single firmware (R4CE012, R4CK003, R4DB005, R4EA031, R4EK001) with all the original (w800, k750, w900, w810) and modified (rufinus, Black Ice, No Hissing, skindeep, ToShaRa, wow, qwerty, AvaloN,…) acoustic possible. I can’t fix it so far. Sorry, IMHO is a hardware problem, and WILL NOT be fixed by Sony Ericsson (see in SE developers forum). Now, I’m using original w800 + no hissing + R4CE012 main file and notice low crackling level.
Notes:
It’s not MP3 quality (bit rate, frequency,…) or earphone problem.
Battery level influences crackling. 100% Battery = no crackling.
It’s a random problem in media player, but always happens when starts fm radio.

battery level does not matter as i've had this problem with my battery at its 100%. i can agree with you when you say it is a random problem.

tranced, I try to use the phone memory instead of memory stick and after +-70% battery the crackling starts the same way in my phone
Using "original w800 + no hissing" acoustic driver (or 800+no_hissing+w810+w900) and 100% battery level, I can play +- 2,5 hours with no crackling. When the battery level drops to 70%, the crackling starts in my phone. I tried that several times.
This weekend, I want to measure and plot a current x voltage curve of the battery and identify the minimum voltage/current value (considering that is the problem
) that trigger the “crackling” effect. That will be complicated because of the location of the battery / phone connector. After that I will use, instead of the regular battery, a DC voltage source with value just a little superior of the minimum. I hope the player will work several hours without crackling.
If it works I think it’s truly a hardware problem (design) or incorrect battery specification.
