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.
