 Posted: Fri Jul 02, 2010 6:56 pm Post subject: alsaconf appears to work but doesn't [solved] |
 |
|
I wasn't quite sure whether to post this in "Kernel & Hardware" or in "Multimedia", but I went ahead and posted it here. Feel free to move it if you feel it's in the wrong place.
Having installed a fresh system, I decided to get sound working after (almost) everything else was up, so I compiled alsa into my kernel as a module, merged alsa-utils, and ran alsaconf which found my card and appeared to set it up. "Fine," I thought, "I'll just run alsamixer to set my volumes and unmute my channels, then I should be able to listen to some music".
Well, alsamixer gives me this message:
| Code: | | This sound device does not have any controls. |
bizarre, non? 
aplay shows that I have no cards installed:
| Code: | orangeblanket linux # aplay -l

If I want to play an mp3 back, mplayer behaves in the following way:
| Code: | $ mplayer 01\ -\ Beck\ -\ Sexx\ Laws.mp3
MPlayer SVN-r29796-4.4.3 (C) 2000-2009 MPlayer Team
Spiller 01 - Beck - Sexx Laws.mp3

my kernel is linux-2.6.33-gentoo-r2
I have media-sound/alsa-utils-1.0.21-r1 USE="nls -doc -minimal"
Is anyone able to tell me what I'm doing wrong?

Lets start with /proc/asound/cards to see what card is it exactly.
Perhaps you simply didn't load correct module. |

| Code: | sam@orangeblanket ~ $ cat /proc/asound/cards
0 [VT82xx ]: HDA-Intel - HDA VIA VT82xx
HDA VIA VT82xx at 0xbfffc000 irq 17

that matches with this information from lspci:
| Code: | 80:01.0 Audio device: VIA Technologies, Inc. VT1708/A [Azalia HDAC] (VIA High Definition Audio Controller) (rev 10)

Does speaker-test produce noise ?
Anything interesting in /proc/asound/ ? |

oh, speaker-test. I didn't know about that one. Well, I gave it a go but it didn't make a noise. It just gave an error:
| Code: | orangeblanket sam # speaker-test
speaker-test 1.0.21
Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise

Playback open error: -2,No such file or directory

as for /proc/asound:
| Code: |
orangeblanket sam # ls -al /proc/asound/

didn't really know what to look for in there... I'll have a scout and see if I can find anything out. |

eheh, you might find that tweaky, but don't just assume VIA HDA= VIA codec 
look at me for example :
| Code: | cat /proc/asound/cards
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xf7cf8000 irq 55
|
so as you see i have an HDA-Intel, and the codec is ... HDA Intel
and it's fine for this card
| Code: |
lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller
|
but, well, no :
| Code: | lsmod | grep snd
snd_seq_dummy 1178 0
snd_seq_oss 21292 0
snd_seq_midi_event 4766 1 snd_seq_oss
snd_seq 38076 6 snd_seq_dummy,snd_seq_oss,snd_seq_midi_event
snd_seq_device 4827 3 snd_seq_dummy,snd_seq_oss,snd_seq
snd_pcm_oss 29257 0
snd_mixer_oss 10968 1 snd_pcm_oss
snd_hda_codec_realtek 189521 1
snd_hda_intel 18595 1
snd_hda_codec 56670 2 snd_hda_codec_realtek,snd_hda_intel
snd_hwdep 4548 1 snd_hda_codec
snd_pcm 53767 3 snd_pcm_oss,snd_hda_intel,snd_hda_codec
snd_timer 14471 2 snd_seq,snd_pcm
snd 43324 15 snd_seq_dummy,snd_seq_oss,snd_seq,snd_seq_device,snd_pcm_oss,snd_mixer_oss,snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_timer
soundcore 4918 1 snd
snd_page_alloc 5901 2 snd_hda_intel,snd_pcm
|
got it ? look, the realtek codec is load.
and looking at my kernel source... | Code: |
cat /usr/src/linux/.config | grep SND_HDA
CONFIG_SND_HDA_INTEL=m
CONFIG_SND_HDA_HWDEP=y
CONFIG_SND_HDA_RECONFIG=y
# CONFIG_SND_HDA_INPUT_BEEP is not set
CONFIG_SND_HDA_INPUT_JACK=y
# CONFIG_SND_HDA_PATCH_LOADER is not set
CONFIG_SND_HDA_CODEC_REALTEK=y
CONFIG_SND_HDA_CODEC_ANALOG=y
CONFIG_SND_HDA_CODEC_SIGMATEL=y
CONFIG_SND_HDA_CODEC_VIA=y
CONFIG_SND_HDA_CODEC_ATIHDMI=y
CONFIG_SND_HDA_CODEC_NVHDMI=y
CONFIG_SND_HDA_CODEC_INTELHDMI=y
CONFIG_SND_HDA_ELD=y
CONFIG_SND_HDA_CODEC_CIRRUS=y
CONFIG_SND_HDA_CODEC_CONEXANT=y
CONFIG_SND_HDA_CODEC_CA0110=y
CONFIG_SND_HDA_CODEC_CMEDIA=y
CONFIG_SND_HDA_CODEC_SI3054=y
CONFIG_SND_HDA_GENERIC=y
CONFIG_SND_HDA_POWER_SAVE=y
CONFIG_SND_HDA_POWER_SAVE_DEFAULT=0 |
It was pickup even i agree alsa to use any. So it's certain the realtek codek is needed for me
to sum up: rebuild the kernel and enable every HDA codec to let alsa have a chance to find the good one for you (even alsa told you it's VIA)
edit: found a real proof it's Realtek one.
| Code: | cat /proc/asound/card0/codec#0 | head
Codec: Realtek ALC1200
Address: 0
Function Id: 0x1
Vendor Id: 0x10ec0888

This is fantastic!
It works. Thank you both for your invaluable help and for solving this problem.
You've made someone very happy today. |

| Thanks, that helped me also a lot. I had sound, but only the front channel was reacting - no master channel or something else. Activating the Realtek stuff for intel_hda solved this. |
