After some thinking, my current plan is exporting audio_drv_list to the Makefile, and then generating something similar to AUDIO_DRIVERS. Notice that the "ordering" problems not only happens with sound drivers, we have the same problems with graphics console, which one is the default one? It depends on what you have configured, and changing the default order is far from trivial.You could pass a goodness value to the registration function, reflecting what we think the best driver is. Then at runtime select the best driver that is supported on the system.I think the easiest way is to forward the sorted driver list as string to the audio layer and let it be processed there. Given such an extension, we could also allow passing a list of drivers via QEMU_AUDIO_DRV.
Sure. Just make audio_init() take an array of strings, have it try and initialize each in that order, then initialize the remaining ones.
I'd say get rid of the compile time ordering entirely. This is the sort of thing that begs for a global configuration file.
