Unfortunately, it didn't work for me.
It started to install about 700 MB of miscellaneous packages, and failed on the
making of the final package.
By precaustion I reverted to a previous snapshot of my system.
Isn't it a simpler way to get debug info?
Is it possible for instance to install libasound-dbg on Ubuntu 11.04?
Maybe my problem comes from run-time link with the library?
Does anyone use Code:Blocks to compile C applications that use ALSA?
If yes could you please tell me the compiler/linker settings to properly use
the ALSA shared libs? I added "/usr/lib/libasound.so.2" to the "Link library"
section of the Linker settings, and it worked, but I still get crashes on the
"snd_device_name_hints", especially within a small Mozilla plug-in in Firefox.
I can send the whole project, with a very easy test that shows the problem if
