            Bug ID: 510120
           Summary: K3b as snap doesn't start burning of Audio CDs and
                    CD-ROMs/Images
    Classification: Applications
           Product: k3b
      Version First unspecified
       Reported In:
          Platform: Snap
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR

  Target Milestone: ---

SUMMARY
K3b, when run as snap, fails to both burn Data and Audio CDs. cdrdao and wodim
immediately return an error when called to start the actual burning.

STEPS TO REPRODUCE
1. sudo snap install k3b
2. snap run k3b
3. Insert a blank CD-R.

For Audio CDs
4. Create a new Audio CD, add some audio files.
5. Click on "Write" (check "Simulate")

For CD-ROMs
4. Create a new data disc, add some files. (Or alternatively try to burn an
image by clicking "Write image file...")
5. Click on "Write" (check "Simulate")

OBSERVED RESULT
Burning fails immediately, without actually trying to access the drive.

For Audio CDs:
Error message says:  
"cdrdao returned an unknown error code (errorcode 1)."

For CD-ROMs:
Error message says:
"cdrecord has insufficient permissions to open the device.
Change your device settings in K3b to solve this problem."

EXPECTED RESULT
Burning succeeds.

SOFTWARE/OS VERSIONS
(all from the About dialog of the K3b snap!)
K3b Version: 25.11.70
KDE Frameworks Version: 6.14.0
Qt Version: 6.9.1

Reproduced with:
* Kubuntu 25.04
* KDE Linux

ADDITIONAL INFORMATION
Attachements: 
* Terminal output of  `snap run k3b` for both trying to burn an Audio CD and a
CD-ROM, plus K3b's diagnosis output for each case.
* Screenshot of the Settings -> Programs -> Permissions dialog.  It seems not
possible to actually change the permissions there, due to the immutability of
snaps.
