>=20
the results:
8k - plays absolute garbage (this is strange, because with 4k it plays musi=
c,
but skips)
16k - plays music, the skips aren't so often heard as with 4k, but are
often enough to be annoying
32k - everything plays fine, even with 3 compilations and heavy disk access.
so, thanks for the quick answer - I will now keep it at 32k, i don't know
the rationale of downing this to 4k. maybe you should commit it to 32k in
the repo too?
