Is there a particular version of PA that I should use those patches
again? I downloaded 1.99.2 and the patches applied cleanly, but I'm
getting a core dump. I'm in the process of building gdb, but here's
partial output from strace:

And these are basically the changes I made to default.pa:


load-module module-alsa-card use_ucm=1
# ### Automatically load driver modules depending on the hardware
available
# .ifexists module-udev-detect.so
# load-module module-udev-detect
# .else
# ### Use the static hardware detection module (for systems that lack
udev/hal support)
load-module module-detect
# .endif

I wasn't sure whether the module-detect was still needed, so I've
tried with and without and I get the same result. Also I tried
use_ucm=0 just for grins, and it also gives the same result.

I copied the Panda, PandaES and SDP4430 config dirs to
/usr/share/alsa/ucm (though I think the latter 2 are unnecessary for
me. My card comes up Panda) and removed the 4430.conf and udev rules
pointing pa to the 4430.conf.

Any suggestions while I try to get the debugger going? Should I be
using current git as opposed to 1.99.2?
