 |
|
Hello,
I've been trying to get my external USB-Soundcard which is a Creative Labs Sound Blaster X-Fi Surround 5.1 Pro (Model-No: SB1095) to work properly for days now.
When I enter:
| Code: | | speaker-test -c 6 -D surround51 -t wav |
it works out of the boxl and I can hear 6 chanel sound on my 5.1 speakers. The basses are produced by the subwoofer, as it should be.
However, when I want to play music, I only get this normal Stereo sound and the basses comes from the small boxes.
The subwoofer doesn't do anything.
I suggest, alsa is working good because of the working speaker-test. Has anybody an idea, how it could be done to listen to 5.1 sound with mplayer,cmus,vlc, etc...
I know, that you might need some additional information about my system configuration or so, but as I don't know what exactly is necessary, I would like you to tell me what you need.
For now, here's the:
| Code: | $ uname -r
2.6.38.2-zen |
| Code: | $ equery list alsa-utils
[ Searching for package 'alsa-utils' in all categories among: ]
* installed packages
[I--] [ ] media-sound/alsa-utils-1.0.23-r1 (0.9) |
Sorry for my poor english, I haven't been practicing the last few years and thanks in advance.

I think so.
(I'm a total noob if it is about sound-things. midi,stereo,pcm,surround,channel,samplerate, etc. I have no clue at all.)
I wonder, why there is no Howto for the USB X-Fi Surround 5.1 Pro on the internet, as it is for graphic-cards.
Do I really have to read over the whole alsa-project for just making this soundcard to give me some music?
As mentioned above, the | Code: | | speaker-test -c 6 -D surround51 -t wav |
-Command shows me, that it is already working.
The subwoofer and all the other speakers get the signal correctly.(front-left,front-center....says the woman) but when I play a Song with mplayer, I only get this Stereo-Sound.
Bass is produced by the small speakers (subwoofer doesn't work at all). Volume-Knob isn't working. In "alsamixer" there is no Volume-Setting for the soundcard.
Can somebode give me at least one or two links to gather up the info I need? I have no idea where to start.
...or perhaps a little howto?
thx |

You need to create and tweak ~/.asoundrc file. I have the same x-fi card with you. Look at my signature, you will see and find my .asoundrc file at the second post of the link. Anyway it is not complete, but works fine and sounds great. Frequencies are adjusted well and speakers routed right. Hope that works for you, too. I use mpd + gmpc for music. So I need to use this config for ~/.mpdconf:
| Code: |
audio_output {
type "alsa" # maybe alsa
device "plug:ch51dup"
name "ch51dup" # maybe equal
}
audio_output {
type "alsa" # maybe alsa"
device "plug:lowpass_21to21"
name "lowpass_21to21" # maybe equal
}
|
If I choose "ch51dup" stereo music is converted to 5.1 sound. If I choose " lowpass_21to21" also frequencies are adjusted which makes sound great on my logitech sound system.

Thank you for your help, but at the moment it doesn't work.
I have copied your ".asoundrc" and have configured the "mpd.conf" but when I want to play music, it says:
| Code: | | ERROR: problems opening audio device |
What could that be? I'm missing the "surround51" plugin in the ".asoundrc", which made my speaker-test work. |

What gives the above ERROR? mpd from console as a user?
How do you play music? with gmpc like me?
Did you select "ch51dup" or "lowpass_21to21" within gmpc in servers menu?

I've both installed gmpc and mpc, they are both issuing this error.

Yes, they where both selected in that menu. |

dr-peppa, anyway I suggest you to start with simple ".asoundrc" and when you have it working you can tweak the file more. Mine is complicated even I don't understand fully.
Use instructions on Creative_USB_X-Fi_Surround_5.1. Use the .asoundrc provided there. It must work. Then we can tweak more. (like freq filtering which is like creative's crystallizer in their win driver.)

I did it that way. Now there is still stereo sound, but i have a "master"-volume bar in "alsamixer" which wasn't there before.
Unfortunately it's not possible to change the volume with this. there is no reaction in alsamixer when i press the arrow-down/up key.
volume knob is still not working. |

Use the .asoundrc belove and check with mplayer if it makes 5.1 sound like this:

mplayer -ao alsa:device=ch51dup somemp3file.mp3

what does this gives?
I think you have to change "card 1" to "card 0" in pcm.dmixed part of .soundrc, as your alsa-info indicates it is recognized as first card.
And probably "card S51" maybe is not recognized with your alsa driver in kernel. So maybe we have to change that to "card 0", too.
Anyway try "card 0" everywhere and let's see what will happen.

I have just changed everything to "card 0". -> no difference.
i wonder, why the sound comes from the on board soundcard when i run mplayer as normal user and
when i run it as root, the sound comes from the external usb x-fi card. |

You use zen-kernel, I am not sure if they have the latest alsa-driver. I needed to replace driver files from 2.6.39 kernel for my kernel-2.6.37-zen0. So aplay list my card as "S51" but yours is listed as "Pro".
Anyway when using with your root there is no .asoundrc in your /root dir, so mplayer chooses your x-fi. But you define .asoundrc for your normal user, and mplayer uses it and chooses onboard card. Maybe card 0 is your onboard card and card 1 is your x-fi card.

I think the difference is that you are using the "X-Fi Surround 5.1" and I am using the " X-Fi Surround 5.1 Pro" My Model-Nr is: SB 1095 and yours could be SB 1090, isn't it?
Yes, I'll try that card 1 |

Yes, you are right, I checked and mine is "SB 1090"
I wonder what is the difference?

It works now!!!! with
| Code: |
mplayer -ao alsa:device=ch51dup test.mp3
|
...or, at least, the subwoofer does his work and the other speakers are ok, too.
But now, the Master-Volume-Bar in alsamixer, has no effect on the volume of the soundcard
and the Volume-Knob on the device is still not working.
Anyway, thank you very much by now. You did an amazing job!!!
I've got to go to work now. I'll be back this evening so don't mind if I don't reply.
THX
edit: before, it didn't work, because I forgot to change one "card 1" to "card 0". your first guess was correct, the x-fi is "card 0"
edit2: is there a way to use the "christallizer" or other synthesizer-settings, as it's possible in windows? |

alsamixer part is easy, but volum knob not. First change the
pcm "dmixed" with pcm "ch51dup" in your pcm.softvol part of .asoundrc.
Then you'll see that alsamixer is able to change volume.
When it comes the volume knob and remote control, (although mine support remote control, I don't have one. So it seems that is the difference between sb1090 and sb10959) you have to use lirc. Take a look at the link I gave before: Creative_USB_X-Fi_Surround_5.1.

christallizer unfortunately is not a hardware but a software part in creative's windows driver. So there is no plus for win users. We can get the similar thing with frequency filtering. It is also enabled in your .asoundrc. But you are not using right now. Since your config now works, restart mpd from your normal user from console:
Now gmpc must be able to play with freq filtered sound if you select only "lowpass_21to21". If you select both "ch51dup" and "lowpass_21to21" you will hear unfiltered sounds, too and it won't work good. Just select one, preferable "lowpass_21to21" for "christallizer" like clean sound. You will notice "ch51dup" is sounds muddy.
Anyway I haven't find a way to use "lowpass_21to21" globally, only gmpc uses it now. That's work of another try.

I've just tried to use only "lowpass_21to21" in gmpc but it doesn't work.
When I turn "ch51dup" off, the sound stops. With only "lowpass_21to21" I hear nothing at all and
I get a notification:

Hey there,
does anyone know, how to switch on "ch51dup" or "lowpass_21to21" on in gmpc?
It's working quite well in smplayer, but not at all in mpd + gmpc...
My .asoundrc:
| Code: |
pcm.!defau
type plug
slave.pcm "softvol"
}
ctl.!default {
type hw
card 0
