1049	bad sound (clicks + low pitch / slower speed)	goblin		"Since I've upgraded mplayer from debian squeeze's 2:1.0~rc3++final.dfsg1-1, sound in one of my .mkv files became weird - hearing lots of clicks and lower pitch and possibly slower speed than it should have (like if you played a vinyl record on too slow RPM).

In squeeze-backports' mplayer version 2:1.0~rc4.dfsg1+svn33713-2~bpo60+1 it was logging lots of messages similar to:


[aac @0x7f1e7b4acbe0]Not evaluating a further program_config_element as this construct is dubious at best.

With latest mplayer with latest ffmpeg, I instead see lots of this (and the problem is the same):
