Comment (by Berbe):

 Replying to [comment:4 cehoyos]:
 > Why does it not work? Did you try -strict -2 ?
 I didn't want to pollute the current ticket focused on the libvorvis bug,
 but here is my try (no, -strict -2 doesn't work, but -strict experimental
 does)
 I don't understand why I need to specify the requested parameters, and
 there seem to be a problem with the channels number.
