Re: [Jack-Devel] jack2 on ARM - patch

Hi,

I've tried the patch in a gumstix overo and it seem to work if I set the
overo as slave. However, when I try

jackd -v -d alsa -d hw:2 -r 44100 &

I get the error below. The overo card is in hw:2, hw:0 is dummy and hw:1 is
loopback. The same jackd command works with them but I can't get the output
in the headphones with those. I've tried the
https://github.com/basilnut/jack2/ but I get the old bus error that I got
with the 1.9.9.5 tarball.
I'm using ./waf configure --alsa
Have anyone used jack2 with a gumstix overo?
I'm using a custom image built with the Yocto project and kernel 3.5.
Another small problem is that libjack* libraries get installed in
/usr/local/lib but jackd looks for them in /usr/lib/... moving then manually
solved this (yes, I did ldconfig after installing it :)

Thanks in advance for reading the question.
