Tommy,

can you please post more details:
- Which GR version?
- What format are your WAV files? (8/16 Bit, Mono/Stereo)
  - Does that matter?
- How large is the WAV file?
- To be clear, this works on Ubuntu, but not on Gentoo? (works on my
  Ubuntu ...)
- Do you know how the output is corrupted?

Are the Ubuntu & Gentoo machine different hardware?

Hm, I'm not even sure what the 'True' does here.. normally you limit the
FG to a number of items with the run() argument.

Also, can you please run this test: Add a throttle after the file
source, and set it to a low value (50k or something). Then run again.
(I'm serious :).
