Bug ID: 452594
Summary: Audio CDs produced with K3B are producing discs with
no sound when the FLAC source file has abnormal
characters in its name
Product: k3b
Version: 21.12.3
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Audio Project
Assignee: k...@kde.org

Difference in filetype descriptions
SUMMARY
***
Audio CDs produced with K3B are producing discs with no sound when the source
file has abnormal/foreign characters in its name. E.G. " ü " "ラ" " ê " etc, and
the source file is of the FLAC file format
***
STEPS TO REPRODUCE
1. Create a new audio CD project with K3B
2. Add a track with a foreign character in the *filename* (not track title
metadata, the actual filename)
3. burn the disc
4. playback the disc in a CD Player, or rip the data from the disc onto a
computer
5. Observe no sound if playing on a CD player, or empty file produced from
ripping the disc
OBSERVED RESULT
When playing the disc in a CD player, or when attempting to rip the music from
the disc back onto a computer, the resulting file will produce only
silence/static (when played in a CD player), or produce a very small file with
only metadata (about 40KB) and no audio data when ripped to a computer.
EXPECTED RESULT
The disc should play the burned music, and the tracks should rip correctly to a
computer with actual audio data in them.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Linux (x86-64) release 5.16.18-1-MANJARO
KDE Plasma Version: 5.24.4
KDE Frameworks Version: 5.92.0
Qt Version: 5.15.3
ADDITIONAL INFORMATION
During the actual burning process, the progress bar shows that megabytes of
data is being written to the disk for the malfunctioning tracks, these tracks
appear to be "empty" and produce no sound when played.
In the bottom of the K3B window where it lists the filetype of the sourcefile,
FLAC files show up as just "FLAC" for the file type when there is a foreign
character in the filename, but show up as "FLAC (Free Lossless Audio Codec)"
from files without foreign characters in them. (See attached screenshot) This
might be related to the bug.
If I transcode the FLAC source with foreign characters to any other supported
format (e.g. mp3, ogg, wav), then use those as the source for burning to the
disk, the corresponding tracks work perfectly.
If I remove any foreign characters from the filenames of the FLAC source files
before importing them into the audio project, they will also burn to the disc
and work perfectly (and not show up as just "FLAC" in the file type, as
described above).
