Fix: (K)ubuntu doesn’t play Audio CD

On Kubuntu 11.10, we have KsCD program installed to play audio CD. The problem I’m having is that some machines could play audio cd and some couldn’t. All machines run Kubuntu 11.10.

To fix this issue, check that /dev/cdrom is a sym link to /dev/sr0 (credit: http://www.kubuntuforums.net/archive/index.php/t-57655.html).

In my case, machines which couldn’t play audio CD don’t have ‘/dev/cdrom’:

# ls -l /dev/cd*
ls: cannot access /dev/cd*: No such file or directory

Let’s create one:

# ln -s /dev/sr0 /dev/cdrom
# ls -l /dev/cd*
lrwxrwxrwx 1 root root 8 2012-07-11 11:38 /dev/cdrom -> /dev/sr0

After this, I can play audio CD.

[Fixed] K3b doesn’t burn mp3 to CD

On Ubuntu 10.10, if you get an error message as the following when trying to create audio CD from mp3:

“Unable to handle the following files due to an unsupported format:
You may manually convert these audio files to wave using another application supporting the audio format and then add the wave files to the K3b project.”

Check if you have libk3b6-extracodecs installed, if not just;

$ sudo apt-get install libk3b6-extracodecs

It fixed my problem.

Banshee crashes: The database disk image is malformed

Banshee just crashed on me with the following error message:

[Info  20:44:59.949] Running Banshee 1.6.1: [Ubuntu 10.04 LTS (linux-gnu, x86_64) @ 2010-06-18 18:47:49 UTC]

I think this is how it happened. My computer hanged while Banshee was running, and I had to force reboot it.  Hence, the Banshee database file was corrupted. Thanks to boombox1387 from Ubuntu forum, this problem can be fixed as the following:

Install sqlite3:

sudo apt-get install sqlite3

Then run:

cd ~/.config/banshee-1

Dump the database in an SQL text format:

sqlite3 banshee.db ".dump" > dump

Backup the (corrupted) database:

mv banshee.db banshee.db.backup

Create and restore a database from dump file:

cat dump | sqlite3 banshee.db

Banshee started up again. Both files: dump and banshee.db can be removed.
