Hi After a break, I am trying to catch up on the brutefir performance test in adk. Unfortunately, with the current revision of adk (2af0538) I get a segmentation fault when running brutefir in offline mode. It can be reproduced by building qemu with brutefir and sox and then doing: cd /etc/ mkdir bftest cd bftest sox -t sl -r 44100 -c 2 /dev/zero -r 44100 -c 2 -b 16 pinknoise.wav synth 1:00 pinknoise vol 0.6 cat > wavtest.conf << "EOF" # Begin wavtest.conf # File used for testing brutefir # Uses dirac pulse als filter. # Stereo only.

On earlier revisions of adk (see oder e-mails) the rest ran fine. I don't really see where this might be coming from. Any ideas or insights are welcome! :-) Cheers Oliver P.S. The config file was modified slightly to avoid the /data path, so the the test can be run from anywhere, now.
