1 Hello esteemed readers
3 After four years in the making, I finally built a new machine. \o/ It's an
4 H97-based board with an ALC892 audio chip. The necessities work, but I'm
5 having problems with the out-of-the-box audio setup. After fixing the card
6 order (analog->HDMI, instead of HDMI->analog) I found another problem:
7 except for KDE, which has its own sound system, all other audio-related
8 programs do not work kcmus, aplay, mplayer, etc). For example:
10 $ play some_file
11 ALSA lib /var/tmp/portage/media-libs/alsa-lib- type is not defined
12 play FAIL formats: can't open output file `default': snd_pcm_open error: No such file or directory
14 So I'm missing the "default" device. Sure enough:
15 $ aplay -L
16 null
17 Discard all samples (playback) or generate zero samples (capture)
18 sysdefault:CARD=PCH
19 HDA Intel PCH, ALC892 Analog
20 Default Audio Device
21 front:CARD=PCH,DEV=0
22 HDA Intel PCH, ALC892 Analog
23 Front speakers
24 [... and some more surround channels plus HDMI]
26 It only lists "sysdefault", but not "default". If I do
27 $ speaker-test -Dsysdefault -c2
28 I get the test noise on both speakers. /usr/share/alsa/alsa.conf defines both:
29 --------->%---------------
30 # redirect to load-on-demand extended pcm definitions
31 cards.pcm
33 pcm.default cards.pcm.default
34 pcm.sysdefault cards.pcm.default
35 ---------%<---------------
36 But why only one shows up, I am at a loss.
39 Could you help me out here please? What is wrong? How can I better debug it?
40 Thanks.
