Changed motherboard now no amarok

[caratuco]

Just a few days ago I changed my motherboard and everything seems to function except amarok and K3b to some extent. Here's what happens when I insert a cd into my cdrom (the same used on my old board) the KDE Daemon will come up and ask "open in new window", "play with amarok", etc. If I choose Play with amarok the playlist will open and everything looks fine. However, when I press play or try to play any track the message "Error loading media: no suitable input plugin. This often means the url's protocol is not supported. Network failures are other possible causes.".
I did an upgrade (not version) and can now play cds with Kaffiene.

Another seemingly related problem is that I cannot play encrypted DVDS with any other application other than Kaffeine , it was not this way before the Motherboard change. I have all win32 codecs, Libdvdcss2, etc., just somehow I have lost the link?

Finally, K3b will stop midway when backing up a newer jacket type DVD. It seems to normally perform half the backup then the cdrom opens, closes, and the second half is backed up. In this case at the mid point the cd will stop and not open just saying something like "reloading media" but never does.

By the way, the reason I just don't reinstall everything is because I have spent months tweaking and really like what I have.
It is Gusty 7.10. The motherboard is: DP35DP w/Q6700. The cdrom is an LG --HL-DT-ST DVDRAM
GSA-H22L
Thanks in advance for any suggestions.

Re: Changed motherboard now no amarok

if the new motherboard is the same as the old one
then there is no evident explanation for what you're seeing.
on the contrary, if the new motherboard is different
(i.e., it has different devices on it), it may simply be
that you need different drivers.

now...
of course you could try and check one thing at a time
(e.g., with sudo lshw and lsmod, etc.)
but i bet it'll be a lot easier (and faster) to re-install the os.

do you know how to go about this without losing your data?

Thanks for responding Jankushka!

I tried sudo lslw and my cdrom was listed. So I tried a sudo apt-get remove --purge amarok with some progress. Now cds will still not play when the daemon prompts me, but if I open the files with Dolphin and select actions>play audio cd with amarok the playlist will be "populated" and finally begin to play. Funny how the link to the daemon does not function?

Re: Changed motherboard now no amarok

alright, then...
let's check the following:

the relevant service desktop file for dolphin:

root> ls -l /usr/share/apps/d3lphin/servicemenus/amarok_play_audiocd.desktop
-rw-r--r-- 1 root root 2028 2008-06-11 15:56 /usr/share/apps/d3lphin/servicemenus/amarok_play_audiocd.desktop

root> grep Exec /usr/share/apps/d3lphin/servicemenus/amarok_play_audiocd.desktop
Exec=amarok --cdplay %u

same for the konqueror's:

root> ls -l /usr/share/apps/konqueror/servicemenus/amarok_play_audiocd.desktop
-rw-r--r-- 1 root root 1855 2008-06-11 16:13 /usr/share/apps/konqueror/servicemenus/amarok_play_audiocd.desktop

root> grep Exec /usr/share/apps/konqueror/servicemenus/amarok_play_audiocd.desktop
Exec=bash kubuntu-media-amarok %u

now...
kubuntu-media-amarok is /usr/bin/kubuntu-media-amarok
which contains the following:

root> cat /usr/bin/kubuntu-media-amarok
#!/bin/bash

DEVICE=$@

if [ -n "$DEVICE" ];then
    if [ ${DEVICE:0:7} = "audiocd" ]; then
        amarok --cdplay ${DEVICE#*=}
    elif [ ${DEVICE:0:1} = "/" ]; then
        amarok --cdplay `dcop kded mediamanager fullList | grep -B1 $DEVICE | head -n1`
    else
        amarok --cdplay /dev/cdrom
    fi
else
    amarok --cdplay /dev/cdrom

eventually check the logical names associated with your cd/dvd in lshw.
then make sure that the necessary links still point to the right device file.
in my case it's /dev/scd0...

root> ls -ld /media/cd*
lrwxrwxrwx 1 root root  6 2007-04-28 18:48 /media/cdrom -> cdrom0
drwxr-xr-x 2 root root 4096 2007-04-28 18:48 /media/cdrom0

root> ls -l /dev/cdrom*
lrwxrwxrwx 1 root root 4 2008-06-10 10:25 /dev/cdrom -> scd0

Re: Changed motherboard now no amarok

Thanks again jankushka!

Everything is the same as your posting until I get to:

ls -ld /media/cd* then I get:

lrwxrwxrwx 1 root root 6 2007-12-27 16:23 /media/cdrom -> cdrom0
drwxr-xr-x 2 root root 4096 2007-12-27 16:23 /media/cdrom0
drwxr-xr-x 2 root root 4096 2007-12-27 16:23 /media/cdrom1

There's possibly something wrong here since I'm only using one cdrom but I did have two before the change.

Also at ls -l /dev/cdrom* I have:

-su: root: command not found

Thanks.
I ran ls -l /dev/cdrom* not as root and got this response:

lrwxrwxrwx 1 root root 4 2008-06-11 18:54 /dev/cdrom2 -> scd0

Re: Changed motherboard now no amarok

oh, good...
this should fix things, then:

sudo ln -s /dev/scd0 /dev/cdrom

and you can also probably get rid of /media/cdrom1 and /dev/cdrom2 with

sudo rm /media/cdrom1 /dev/cdrom2

but i would just leave them there.
they'll do no harm, anyway.

Re: Changed motherboard now no amarok

We're close I think.
sudo ln -s /dev/scd0 /dev/cdrom worked perfectly, however it seems to be temporary. When I power down and restart The link is not retained and I have run sudo ln -s /dev/scd0 /dev/cdrom
again.
Perhaps this can be run as some sort of script at startup, which I don't think I know how to do either.

Thanks again.

Update: I decided to try to repair the DVD end of this situation and found this post
http://kubuntuforums.net/forums/inde...opic=3093102.0

This fixed my DVD problem and as I looked at the contents of the "70-persistent-cd.rules" file I saw that I had two entries for my drive, one for cdrom and one for cdrom2. By changing cdrom2 & cdromrw2 to cdrom & cdromrw all is well.

Thanks again jankuska for pointing me in the right direction!
