Well, we have the selectors for the default device in winecfg. That lists all
of the devices that are discoverable by winealsa.drv. Unfortunately, there
doesn't seem to be any way to get a list of devices from ALSA. I saw your
recent mail to alsa-devel. Hopefully they respond with something useful. I
expect they won't.

If not, I guess we could add (or re-add) a registry entry for undiscoverable
devices. Perhaps a comma-separated list of device names. It really sucks that
the user would have to input this.

Looking at VLC, they also use snd_card_next(), snd_ctl_pcm_next_device() and
friends to do device enumeration. mplayer has a bunch of hard-coded defaults
("default", "surround40", "surround51", "plug:" prefixes for each of those),
although there's no documented location of those device names as far as I'm
aware.

Hooray ALSA... We should move this discussion to a separate bug.

I thought we did have a bug where we discussed adding handle_underrun (before
your Bug 28040), especially in context of StarCraft 2, but I can't find one.
Maybe that was discussed entirely on IRC.
