Yes but, after reflashing a device, what is the element that causes the problem?
There must be something.. I prefer prevention rather than cure

I am not convinced...
I deinstalled hildon-welcome to even have a faster boot time, the link to /opt is existing

Code:

ls -la /usr/lib/ | grep FLAC
lrwxrwxrwx    1 root     root           16 Nov 14 06:09 libFLAC.so.8 -> libFLAC.so.8.2.0
lrwxrwxrwx    1 root     root           35 Nov 14 06:09 libFLAC.so.8.2.0 -> /opt/maemo/usr/lib/libFLAC.so.8.2.0

but i only had sound problems once when i upgraded the phone from terminal and had to downgrade

libflac8, installed as a dependency by decoders-support, never seen the issue on < PR1.3 tbh

I'm not convinced this fully explains it. After my system has booted (ie when /opt has definitely been mounted) running "start pulseaudio" still sometimes gives the "pulseaudio respawning too fast, stopped" error (as per No sound throughout the OS)

The solution given here Sound on my n900 does not work at all works for me.

Upstart keeps trying to start pulseaudio till it fails (this all happens before /opt is mounted), if it fails too many times, you'll get respawning too fast, feel free to try again after 5 minutes, it should start properly.

Two days ago: with 2 terminal windows & 2 browser windows and conky
Incoming call. Phone responded very very slowly (took 5 minutes or so just to swtich to desktop and even froze after a short while. There was sound still.
After rebooting the call came in again. I wish the caller had not kept dialling to me when my phone hanged because of these calls... This time the phone didn't rang at all but just kept vibrating while the phone froze again. The vibrating went on like forever even if the call session was ended. I could do nothing but press the power button to turn off the phone.
Since then my phone remained muted up to now.
Making calls for the first time after every rebooting often failed and didn't go through.
Even calls are okay afterwards there is no sound.
The volume bar moved itself to the far left every time it rebooted. Adjusting it, turning on speaker, plugging in headphones (the icon was "dim" on menu bar while it should be lit). No sound.
That's bad. Really really bad.

I suspect some common cause must be happening but why all the suggested fixes failed on me? :-?

I've tried all these:

1) apt-get --reinstall install libflac8

2) rm /usr/lib/libFLAC-8.2.0 && cp /opt/maemo/usr/lib/libFLAC-8.2.0 /usr/lib

3) apt-cache policy libsndfile1
apt-get install libsndfile1=1.0.20-0maemo1+0m5

4) killall gst-video-thumbnailed

5) dmesg | grep pulseaudio
ps ax pulseaudio
no output...

stop pulseaudio && start pulseaudio
start: pulseaudio respawning too fast, stopped
(after trying many times)
main process 2186
pulseaudio (start) running, process 2186

ls /usr/bin/pulseaudio showed -rwx------

6) (as root)
pulseaudio --kill
E: core-util.c: Home directory /home/user/ not ours
E: main.c: Failed to kill daemon. Permission denied.

7) apt-get --purge remove decoders-support

Is there any more fixes to try? Reflashing is not an option as my whole filesystem has already grown to 6GB and my backup was way much smaller that this, and more importantly, why we always have to do reflashing just because f some nasty bugs in one app?

Some more output messages in exact sequence:
(decoders-support has been purged)

Okay ... sound comes back
Instead of reflashing, using 'cp -au' to copy the everything in the filesystem from the backup and then rebooting fixes the problem and the current filesystem remains intact.
But I still want to know why pulseaudio suddenly stops working...
