The AG CVS version of rat at the time I released the FC5 AG rat RPM only had
support for the old ALSA 0.5.x API (which was incompatible with the current
ALSA 1.x API), so no native ALSA support was built.
In the past with the AG2.4 Fedora RPMs, I was building Steve Smith's rat
from his DARCS repository which included ALSA support (and was 64bit clean),
but the input unfortunatelly sounded robotic. So when I went back to AG rat
with AG3, I didn't patch it for native ALSA support.
For FC6 as an interim solution till UCL rat could be used, I patched the AG
rat CVS repository with UCL rat's ALSA code. It probably explains why the
FC6 AG rat no longer has the robotic sound problem with ALSA.
