        Hi!

 I'm yet another person who noticed this annoyance.

 The audiotestsrc never gave me crackling sound, only actual tunes,
mostly deep bass parts, and only with width/depth set to 32, 16 works
perfectly. The set volume doesn't make any difference, audio players
that don't use gstreamer play the tunes perfectly.

 How much higher do you want? I added two zeros to each of the numbers
with no real change ...

 Doesn't change anything neither, sorry.

 Which bugreport do you want to have the discussion continued, btw.?
