Package: vlc
Version: 1.1.7-3
Severity: important
After an 'apt-get upgrade' (which upgraded vlc), the sound of
my radio station (a premium paid-for 'MPEG 1.0 layer III, 256 kbit/s,
44100 Hz joint-stereo' stream), started to sound HORRIBLE.
Like really really cheap. I detected that there was much less
clear high-tone, less depth and less stereo and that everything
sounded like there was a slight echo (as if standing in room
without furnature). I then tried to play an .mp3 file from harddisk
and it had the same sound quality. I could compare this with playing
it with mpg123 which sounded good to my ears (at least, sounded like
this is how it was encoded in the file).
Of course I tried to change preferences to see if I accidently
had enabled some audio filtering, but this wasn't the case as far
as I can tell.
I tried uninstalling everything related to vlc and reinstalling,
but it stays unacceptable. I have no removed vlc from my system
and am using mpg123 from a command line to play my radion stations,
very much not desirable, but the quality of vlc has dropped far
below what is tolerable.
