After a recent update ALSA stopped working. Apparently, ALSA now
defaults to a device that doesn't work (fails to open, or just hangs).

On Gentoo, with OpenRC, how do you configure the default board/device
for ALSA?

I've asked Google, and all the links it comes up with are for sites
that are broken because of PHP or database failures (e.g. wiki.gentoo.org
and forums.gentoo.org).

The usual fallback is wiki.archlinux.org, but its instructions to
place the following in /etc/asound.conf or ~/.asoundrc doesn't work:

defaults.pcm.card 1
defaults.ctl.card 1

Likewise the wiki.archlinux.org advice to set ALSA_CARD to the card
name shown by aplay -l also doesn't work.

How do you set the devault card/device for ALSA on Gentoo?

wiki.gentoo.org is back, and it says to use something like this in /etc/asound.conf
or ~/asoundrc:

defaults.pcm.!card 1
defaults.pcm.!device 0
defaults.ctl.!card 1

That also does nothing. Using card names as shown at https://wiki.gentoo.org/wiki/ALSA#Files also does nothing.

Yes, I'm restarting alsasound after changing /etc/asound.conf

The only way I can get sound is to specify the card using -D with
aplay, or using -ao alsa:device= with mplayer, or by manually choosing
the correct output device in VLC.

Apparently, restarting alsasound after changing /etc/asound.conf isn't
enough. A reboot was required.

I never saw that mentioned in any of the half-dozen sources I read
about alsa configuration, so I presume it's a personal problem?

These configurations are in /etc/modprobe.d/alsa.conf as to which is
the default sound card and its parameters. The name might not be
alsa.conf, but you would have to unload the module and reload, that is
why you had to do a reboot.

I believe that file is only used if alsa is a module. I've never
configured alsa as a module.

I have always had alsa built in to the kernel, and the default
configuration is in /usr/share/alsa/alsa.conf. That file is the one
installed by installed by the emerge, and generally should not be
edited. System-wide settings should go in /etc/asound.conf and
per-user settings should go in ~/.asoundrc.

Those files are both included by /usr/share/alsa/alsa.conf.
