[Cin] Variable bitrate file processing problems

[preobraz at gmail.com]

Why I did not try to open the file on a clean profile - I do not know. 
Many thanks for the tip! Also, it turned out to start the sound by 
changing the device in the program settings.
Here is a link to the archive directory /tmp/bcast5:

although now everything works for me.
Thanks again for the help.
