Welcome to Linux Questions.
Only libasound.a and libasound.la files were generated.
'libasound.a' should not be created, unless the option
" ./configure --enable-static " was used.
In fact the shared libraries,
libasound.so.2.0.0* libasound.so.2@ libasound.so@
will be made by default, no options needed for that.
Please see : './configure --help'
