You'd mentioned that this problem was present in ALSA 1.0.25, but wasn't
in some earlier release. Potentially a lot changed between those two
releases. It'd be nice if you could try compiling a number of
intermediate versions of the ALSA driver to try and more precisely
locate the change that caused the issue. "git bisect" on the ALSA driver
repository might be useful here.
