No, I have just installed preenv after reflash no problems
so far. It must be a different thing.

Well one side effect of audio not starting up at boot is that the boot video is not played and that seems to substantially speed up the boot process

On device start the system starts the pulseaudio daemon.
As it needs libFLAC the system tries to load this library.
The library is at
/opt/maemo/usr/lib/libFLAC.so.8.2.0

So the application pulseaudio fails to load
(cannot load library libFLAC.so, no such file)
Because all this happens before the internal mmc is mounted :-)

After failing to start the daemon the system tries this again and again.
It may work at some point when the internal mmc is mounted.
But sometimes the restart (respawn) happens to often and
the system stops this process.

I don't know why pulseaudio needs this lib, it has something to
do with the package decoders-support. But it seems this only
happens if you upgraded to PR1.3.

I did a reflash now and installed decoders-support.
The libFLAC library is on /opt/maemo ....
But pulseaudio starts without an error.
(And it does not depend on this library anymore,
ldd /usr/bin/pulseaudio shows which librarys are needed
by an executable/library).

Code:

Nokia-N900:~# ldd /usr/bin/pulseaudio | grep FLAC
        libFLAC.so.8 => /usr/lib/libFLAC.so.8 (0x4060b000)
Nokia-N900:~# ls -la /usr/lib/ | grep FLAC
lrwxrwxrwx    1 root     root           16 Oct 26 23:20 libFLAC.so.8 -> libFLAC.so.8.2.0
lrwxrwxrwx    1 root     root           35 Oct 26 23:20 libFLAC.so.8.2.0 -> /opt/maemo/usr/lib/libFLAC.so.8.2.0
Nokia-N900:~# cp /opt/maemo/usr/lib/libFLAC.so.8.2.0 .
Nokia-N900:~# cp libFLAC.so.8.2.0 /usr/lib/
Nokia-N900:~# ls -la /usr/lib/ | grep FLAC
lrwxrwxrwx    1 root     root           16 Oct 26 23:20 libFLAC.so.8 -> libFLAC.so.8.2.0
-rw-r--r--    1 root     root       303348 Nov 15 10:40 libFLAC.so.8.2.0

Fixed it by copying it from /opt/ to /usr/lib/. No idea if this causes problems at later but atleast this **** starts now at boot times.

Hi,

Yesterday I uninstalled power kernel and I can in fact confirm that it is not related to that kernel.
It's like nicolai said and sickki further developed and most likely related to the PR1.3 update.
But why isn't it affecting more people? (considering there aren't many posts)
And also why does pulseaudio refuse to start at times, even when you start it manually? (sudo gainroot; start pulseaudio)

I'm going to try sickki's workaround and see what happens.

*EDIT* I already had this file in /usr/lib/ on rootfs (but also in /opt/maemo). Or are these symbolic links??? (how do I tell the difference?)

*EDIT2* thanks, sickki. The files in /usr/lib/ were symlinks indeed. Copied the library file from /home/opt to rootfs.

If you write this: ls -la /usr/lib/ | grep FLAC

lrwxrwxrwx 1 root root 16 Oct 26 23:20 libFLAC.so.8 -> libFLAC.so.8.2.0
lrwxrwxrwx 1 root root 35 Oct 26 23:20 libFLAC.so.8.2.0 -> /opt/maemo/usr/lib/libFLAC.so.8.2.0

It should show this: libFLAC.so.8.2.0 -> /opt/maemo/usr/lib/libFLAC.so.8.2.0 means that it's just symlink to /opt/.

Just write: cp /opt/maemo/usr/lib/libFLAC.so.8.2.0 /usr/lib/libFLAC.so.8.2.0

If you wan't to try fix what helped for me.

@sickki thanks a lot, I see if audio doesn't stop anymore, and I'll let you know

EDIT:
IT WORKS! THANK YOU VERY MUCH!

I just ended up reflashing my phone. That had nothing to do with the audio bug, I just kinda installed Multiboot on top of Uboot just to see what would happen. My configuration is almost identical but so far I haven't had any issues.
