+---- Thread: clicking noise on MP3 with VBR (/showthread.php?tid=89850)
clicking noise on MP3 with VBR - popelheini - 2011-01-07
I have upgraded from 9.11 to latest CVS. I have running FC14 on Acer Revo 3610, sound goes through HDMI.
After successful upgrade I have identified clicking noise on MP3 with VBR. MP3s with fixed bitrate seems to be ok. The affected VBR MP3s are ok on my iPod too.
Does anybody have an idea?
I wouldn't put money on it, but on 9.11 I didn't notice this issue.

I never expected so many replies ;-)
I have tested again. When sound goes through optical, the problem is still the same.
When I connect my USB headset, I can't hear the clicking noise. Could it be a problem of the sound chip on Acer Revo 3610?

Reason for the clicking noise is an update of glibc which changed memcpy().
memcpy() can only be used if memory areas are not overlapping (as defined in POSIX standard), which seems to be the case at my setup.
memcpy() somewhere in XBMC source has to be replaced by memmove().
I have opened the ticket #11129 for this bug. A workarround is available and described at
