When I try to use csound in real time using rtalsa I get errors

 unknown rtaudio module: 'alsa', using dummy modulertaudio: dummy module enabled
writing 512 sample blks of 64-bit floats to dac:hw2,0

but librtalsa.so exists and has no missing references
> ldd librtalsa.so 
        linux-vdso.so.1 (0x00007ffd045bf000)
        libasound.so.2 => /usr/lib64/libasound.so.2 (0x00007f3c82857000)
        libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f3c82833000)
        libm.so.6 => /lib64/libm.so.6 (0x00007f3c826e8000)
        libc.so.6 => /lib64/libc.so.6 (0x00007f3c824f3000)
        libdl.so.2 => /lib64/libdl.so.2 (0x00007f3c824ee000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f3c82989000)
what am I missing?
