Please, do not confuse people with comparing apples and oranges.

Linux driver, corresponding to our deprecated base version (v3.8), also has
radeon_audio set to 0:
https://github.com/torvalds/linux/blob/v3.8/drivers/gpu/drm/radeon/radeon_d=
rv.c#L144

While current FreeBSD driver has radeon_audio set to -1:
https://github.com/freebsd/drm-kmod/blob/5.4-lts/drivers/gpu/drm/radeon/rad=
eon_drv.c#L193

I don't know, if it works though.
