Bug#885080: brasero: Can not burn from MP3s directly to CD

[Tony Houghton]

Package: brasero
Version: 3.12.2-4
Severity: normal

I tried to create an audio CD from a set of MP3 files, using Brasero's
default options. Everything appears OK, including correct reporting of
how much free space will remain on the disc (which may be significant
for another bug I'm about to report), until a dialog appears saying
"Burning audio CD" ... "Starting to record". This is suspect, because it
appears before Brasero could have had enough time to decode the MP3s.
After a few seconds it freezes, without using significant CPU, and has
to be killed.

Brasero is able to create a valid cue/bin image from the files, which
works after burning with cdrdao, but Brasero can't actually burn this
image itself. The symptoms are somewhat different, so I'll report that
as a separate bug.

My drive is a SATA DVD-RAM burner branded LG, which Brasero identifies
as HL-DT-ST DVDRAM GH22NS70.
