Hello esteemed readers
After four years in the making, I finally built a new machine. \o/ It's an
H97-based board with an ALC892 audio chip. The necessities work, but I'm
having problems with the out-of-the-box audio setup. After fixing the card
order (analog->HDMI, instead of HDMI->analog) I found another problem:
except for KDE, which has its own sound system, all other audio-related
programs do not work kcmus, aplay, mplayer, etc). For example:
$ play some_file
ALSA lib /var/tmp/portage/media-libs/alsa-lib-1.0.27.2/work/alsa-lib-1.0.27.2/src/pcm/pcm.c:2109:(snd_pcm_open_conf) type is not defined
play FAIL formats: can't open output file `default': snd_pcm_open error: No such file or directory
So I'm missing the "default" device. Sure enough:
$ aplay -L
null
Discard all samples (playback) or generate zero samples (capture)
sysdefault:CARD=PCH
HDA Intel PCH, ALC892 Analog
Default Audio Device
front:CARD=PCH,DEV=0
HDA Intel PCH, ALC892 Analog
Front speakers
[... and some more surround channels plus HDMI]
It only lists "sysdefault", but not "default". If I do
$ speaker-test -Dsysdefault -c2
I get the test noise on both speakers. /usr/share/alsa/alsa.conf defines both:
--------->%---------------
# redirect to load-on-demand extended pcm definitions
pcm.cards cards.pcm
pcm.default cards.pcm.default
pcm.sysdefault cards.pcm.default
---------%<---------------
But why only one shows up, I am at a loss.
Could you help me out here please? What is wrong? How can I better debug it?
Thanks.

Including an HDMI device? (in case your board has an HDMI connector at all)

I have this enabled for programs that need /dev/dsp, such as sidplay.

Didn't have that one enabled.*

Your kernel must be a bit older. My 3.16 doesn't have this and instead has
an "HD-Audio" entry right next to "PCI sound devices".

This is a module for me, but it gets auto-loaded.
* I toggled those settings and rebuilt, but the result is still the same.

You may have to configure your sound card setup manually. It's not as
scarey as it sounds. First question; what's the output of the command...
cat /proc/asound/cards
...on your PC? On my system, it's...
[d531][waltdnes][~] cat /proc/asound/cards

First an elementary question. Please don't treat this as an insult.
Do you have the "alsasound" service running? I have an openrc machine.
I don't know the equivalant systemd commands. As a regular user, execute
/sbin/rc-update show
...and alsasound should show up near the top. If it doesn't, that's
probably your problem. In that case use su or sudo for root privileges
and execute the following 2 commands as root...
rc-update add alsasound boot
/etc/init.d/alsasound start
The first command will cause alsasound to run at every bootup; the
second command is just for this time only, so you don't have to reboot.
Try playing sound again.
#######################################################################
If that doesn't work for you, "Plan B" is to create a .asoundrc file
in your home directory. It will over-ride /usr/share/alsa/alsa.conf and
you won't need root permissions to edit it. If you want the PCH
(analog?) to be the default, enter the following 3 lines in ~/.asoundrc
defaults.ctl.card 0
defaults.pcm.card 0
defaults.pcm.device 0
If you want the HDMI as your default, enter in ~/.asoundrc
defaults.ctl.card 1
defaults.pcm.card 1
defaults.pcm.device 1

I won't, you can't know everyone and I am not *that* regular a participant
in the list. However, I've been a Gentoo guy for 8 years now and I should
know the basics by now ;-) (although I had my share of cases of negligence).
> Do you have the "alsasound" service running?
It has been in the default runlevel for a number of days now. The service is
also running right now.

*That* is what I was looking for. My intertubes search also guided me to
.asoundrc, but I had something different in it:
pcm.!default {
slave.pcm "pch:1,0"
}
Which didn't work.
When I edited .asoundrc as you suggested and it worked right away, I was
baffled. So I reverted the change and checked again -- still working.
Somehow, like other issues I had in the past, it “solved itself”, because
now aplay -L does give me a "default" device.
Yesterday, when I tried your kernel settings, rebuilt and rebooted, it did
not help. Unfortunately I didn't keep my old kernel config; I was unable to
reproduce my problem by reverting my config from memory. So this is another
one for the big book of mysteries, never to be remembered again. :-/
Thanks for your time.
