How to make Android play music reliably, without chopping?

When I try to play music on Android 2.3 (using various players, including PowerAmp) on Sony Ericsson Xperia X10 I get not reliable sound. Music pauses for a short time, for example, when:
* I press the power button (especially repeatedly) (
request_suspend_state: sleep;request_suspend_state: wakeup
in dmesg)
* When I see messages like send sigkill to 15497 (ndroid.settings), adj 8, size 6428
in dmesg
* When some program reacts to changed screen orientation.
* When wifi connection gets established, when I force it to "reassociate"
* When I go to/from application from home screen (AWDLauncher), except of to/from WidgetLocker screen.
* When I enable/disable Airplane Mode.
* When the display is off (the most annoying)
When only really stable way to play music is to use StayAwake to force display on, turn off Wi-Fi, turn on Airplane Mode and don't switch applications. Starting CPU hogs like while true; do true; done
does not affect chopping.
And it was playing more or less fine on Android 2.1.
"mediaserv" process (that writes to /dev/msm_pcm_out) has realtime io and scheduling priority, but sound is choppy anyway. If I start playing from console with mplayer -ao pcm:file=/dev/msm_pcm_out
the sound chop less (notably it does not get interrupted by power button / loading bunches of heavy processes), but still behave not normally when screen is off (even ionice -c1 -p4 cat /dev/urandom > /dev/msm_pcm_out
is choppy)
When I start music A by usual way and music B using mplayer to /dev/msm_pcm_out (getting them mixed) music A chops more than usual and I usually hear B when A is in chop. When I turn off screen, both A and B chops in sync (stopping B leads to relatively more fluent playback of A this way).
How to play music on Android reliably in presence of background load? Should I report a bug somewhere?
Update Found a way of playing music. Inconvenient, but _without chopping_:
1. Start WakeLock in "CPU on, Screen Off, Keyboard off" mode
2. Use mplayer to play music bypassing Android:
ionice -c1 -n4 \
schedtool -R -p 3 -e \
mplayer -really-quiet \
-af volume=-26 -quiet \
-ao pcm:file=/dev/msm_pcm_out,nowaveheader \
/mnt/sdcard/music/something.ogg
# (created script to start it easily, of course)
Plays without chopping no matter how much applications I start, what do with Wifi, orientation and airplane modes. Even with "powersave" cpufreq governor (everything very slow, but music plays fine). So the hardware have enough resources to play it.
Update 2
Looks like doing
for i in pgrep ''
; do schedtool -D $i; done
i.e. "Set Idle priority for all processes" makes music play fine even when I {start programs,lock screen,rotate screen;it reconnects to other mobile network stations} at expense of some input lag in games. Don't know exactly why it happens.

How do I change a Google account for Android mobile (Xperia 10)?
When I first set up my Xperia 10 (running Android 1.6) I selected a 'dummy account', not knowing that it might be somewhat difficult to change it afterwards to a real account (I wasn't warned). I want to avoid hard resets or losing too much data. Is there a recommended procedure for this case?

My PC - well, specifically, Flashtool - doesn't detect that my X10 has USB Debugging turned on, even though it displays that it has been activated both in the Settings menu and the notification shade. I've tried the modded Flashtool from XDA-Dev, and the latest versions, but to no avail. Any suggestions? I believe the drivers are up to date, as I can turn storage mode on when plugging it in and transfer files just fine. Rooted, running stock. It was fine pre-root, but as soon as I rooted it the first time around, it hasn't been able to detect. Recovery can't be flashed due to the lack of debugging.

It seems great, but one thing I do not like is that I have to sync my whole life with google first, before I can transfer it. The previous software allowed me to copy back and forth between PC and phone,without going onto the internet.
Hopefully it is something I'm doing wrong, because if it is not, I'm changing OS!

I am new to this forum and would really want to please help me get this problem solved. I just bought a **Sony Ericsson Xperia X10** and tried connecting it to my internet at home (**Belkin N1 router - 64-bit WEP encryption**) but it does not connect at all. It catches the internet connection and says its in very good range, I put the key but it never connects. I have tried all the different things possible via this forum, googling for answers, etc but haven't found a solution yet.
**Stuff that I have tried:**
1. Tried accessing it via a static i/p technique.
2. I cannot change the WEP encryption to WPA-PSK because the internet
is set up by my landlord and I am not allowed to change it. I can
check the settings and it shows access to all b/g/n configurations.
3. I have another phone i.e. the new Sony Xperia S, even that is not
able to connect to my wifi.
4. I am able to connect both these phones very easily to other wifi's
having WPA-PSK connectivity but just not my home network.
**Update:**
I have been able to partially solve the problem but it is not the exact solution that I am looking for. Here's what I have tried:
I have tried the WPA-PSK approach (AES encryption) and it does somehow make it work on my Xperia S (it did not connect to it instantly). Basically, there is an option of WPS (Wifi-Protection Setup) in my Xperia S which allowed me to do a Push Button Configuration (PBC) i.e. holding the router button for 3 seconds to allow my phone to access it. It assigned me an i/p address and thus made it work but spoiled it for my other housemates, so I had to get the setting back to WEP.I know it is more secure to use WPA, but I cannot change it without asking my landlord. Anyways, the point is that somehow my other phone connects to the router not instantly but via some route as given above. My question again is: Is it really not possible to connect it via WEP?
Kindly help as I have been struggling a lot to find for a proper solution over the internet.

A couple years ago, I picked up an Xperia X10i secondhand. The phone itself has been working great; no problems whatsoever. It's a real workhorse. I unlocked it almost instantly, and followed some steps I Googled way back when to open it up completely. I can't quite remember what it was, but it was supposed to root the phone. I don't think I managed to actually root it, but it's been working fine, regardless.
Lately, I've been wanting to update the firmware on it. Every time I use the Sony Ericsson PC Companion or Update Service, though, to try to update the firmware, it just tells me I have the latest version.
How can I go about updating this to 2.1 or higher? Are there steps a technically-savvy, but Android newbie could follow to update the firmware?
I'm willing to blow it all away if I have to, although I'd really prefer to not have to do that.
