The backward compatibility is guaranteed. That's the very reason that such a versioned symbol was introduced. (And it was a big failure...) Please don't mix up the things about config files and the library ABI compatibility. In a very rare case, the configuration file doesn't match with the driver version. This happend once on emu10k1 (and people now think that it's a frequent case, unforunately, although we've tried to keep the compatibility of config stuff since then). But, the ABI is kept backward-compatible for many years. So, you don't have to use the same version of alsa-lib. In general, the newer version is always better. The newer one includes more bugfixes and new features. BTW, the problem here looks like a build of alsa-lib with versioned symbols. Or, the app isn't linked to libasound at compile time, so it couldn't resolve the versioned symbols properly. It's a common problem with versioned symbols.
