[Qemu-devel] Help debugging audio problem

[Programmingkid]

What does this code mean? 

 if (!glue (s->nb_hw_voices_, TYPE)) {
        return NULL;
    }

The code is found in audio_template.h at line 244. 

I tried using GDB to figure out what it was doing, but had little luck. 

The AC97 sound card does not work, and I'm trying to change that. 

Any help would be great. Thanks.
