>Description:

hdaudio(4) doesn't support mmap. grepping in src/dev/pci/hdaudio reveals

dev/pci/hdaudio/hdafg.c:        /* TODO: AUDIO_PROP_MMAP */
dev/pci/hdaudio/hdaudio.c:      .d_mmap = nommap,

One consequence of this is that sound in games/tyrquake doesn't work.

There doesn't seem to be a PR already on file for this, so I'm
creating one.

>How-To-Repeat:

>Fix:

I have no idea what this entails.
