 Posted: Wed Feb 07, 2007 2:35 am Post subject: big problem with ALSA or/and OSS |
 |
|
Hello,
now I'm on testing since like 3 days and I don't get is perfect. If I will use OSS in my kernel I see that the sound card is a 6 channel soundcard (ICH5 i8x0 onboard) based default 2 channels. So I only hear the sound in my REAR Speakers 
So in case that OSS is DEPRECATED in the 2.6.19 kernel I use now ALSA in my kernel (fix included) and now this would be work a little bit better but like in a stadium where I will get a horror 
I have installed the alsa-utils and have configured as described in so many how-to's the ALSA with the alsamixer. So now I can test it with
| Code: | | speaker-test -c6 -twav -D surround51 |
but with the result that I hear FRONT LEFT, FRONT RIGHT but nothing more. So it seems that there is a problem with the surround channels but I have activeted 6ch in the alsamixer.
In one thread there was a help to generate/write a .asoundrc and .openalrc but this don't will help too. So now I'm a little bit disfused because I don't know how to fix this shit stuff. Maybe I have disconfigured my alsamixer but I don't know which parameter must be in which way in the /etc/asound.state.
Can anybody send a correct /etc/asound.state code for an ICH5 chip ?? Or can anybody tell me which Lines/parts I must activate or deactive in the alsamixer ??
Many thanks in advance

Are you sure all sliders in alsamixer are above the 50%? By default all channels but front left/right are muted and set to 0.

Hello,
if I will turn off all slides I get a big tone out of all boxes which isn't really what I like. Ok I've the following slides at this moment :
| Code: |
Master ON 90%
Master Mono OFF
Master Surround ON 90%
Headphone OFF
PCM ON 81%
Surround ON 90%
Surround Jack Mode Independ
Center ON 84%
LFE ON 84%
Line OFF
LIne Jack Sense OFF
CD OFF
Mic OFF
Mic Boost OFF
Mic Select Mic1
Phone OFF
Aux OFF
Channel MOde 6ch
Downmix OFF
Exchange Front/Surround OFF
External Amplifier OFF
High Pass Filter ENable ON
Spread Front to Surround and Center/LFE ON
V_REFOUT ENable ON
|
Maybe some isn't on or in wrong way. But maybe you can tell it which slider could be wrong.
I've the AlsaMixer v1.0.14rc2 installed

These settings look good. But I miss the "Duplicate Front" switch that should come with the intel8x0 module...

hmmm ... maybe it is in case that I have compiled the ALSA directly into the kernel (not as module) but with direct compile it works better as with module compile. It seems that on a real 64bit system it is better to have it directly in the kernel.
I will take a look to the new 2.6.20 kernel (now I use 2.6.19-gentoo-r5) in the next days. But maybe there is only a wrong entry in the /etc/asound.state ?? I will post it.

you could try reconfigure alsa with alsaconf.
AFAIK the asound.state just remerbers your volume settings so that they can be restored after reboot. But I could be wrong now...

alsaconf wouldn't work on my system because it don't knows any PnP card 
but the alsamixer levels are stored with /etc/init.d/alsasound save and alsasound is added with rc-update in the boot-level. So it restores the levels after each reboot |

do you know/have a link for a MP3 test file which is stored in 5.1 sound ??
because I have only WAV files but my Amorax-Player (which can use 6ch) cann't play them.
maybe I've 5.1 sound and the ALSA works but cann't hear it in case of a wrong player configuration  |

hi again,
so it seems to be work - but I'm not 100% sure but now I get sound near 5.1 out  To find 5.1 MP3 isn't hard - you can found it here http://www.all4mp3.com/music/ - the best to hear it I think is from Tchaikovsky (Swan Lake - Actll - Scene Moderato - Classical) 
What I've done :
I've changed the kernel from fix compiled (only the PCI devices from ALSA) to module compiled. Why it runs now different please ask another person  but it seems to be better because like alsaconf now find a soundcard and should work/load the driver in other way *maybe*
I don't changed anything on the mixer settings because they are right (but I don't have the "duplicate front" already) and I don't have installed the alsa-driver *you don't need it*
Thats all
The only strange think is that the speaker-test don't work - here I will only get a "front left and front right" but nothing more but I hear it at same time in Front and Rear Speakers stupid.
cu alex
P.S. if somebody needs any config please give me a hint  |

ahh .. i've forgot 1 big info :
I've changed the "Surround Jack Mode" from "Independ" to "Shared"
cu alex
P.S. but now with the modules I've the problem that the rebuild of the mixer settings don't work for the "master" but for all others |
