How can I know which audio driver have I installed and using it?
 

Hello
Can I have installed Pulceaudio and Alsa and other drivers installed for my audio card at the same time, and just change them in any text configure file orsomewhere?
How can I know what I have installed? And how can I change between one driver and other?

Open a konsole and run the command '/sbin/lsmod | grep snd' ( without the quotes ). This will list the alsa modules you have loaded.

If it working, you have the correct modules loaded. If not, then you may still have the correct modules loaded, and are not passing the correct parameters to the modules. It is also possible you have the wrong modules loaded, and it is not working.

You use the command 'modprobe modulesnameyouwanttolaod' to load a module. You use the same command to unload a module. There are config files that cause the modules to load on each boot.

Pulse Audio is a sound server, not a driver. Its job is to take sound from various sources, and route it to the audio hardware to make sound. Have a look here -->http://www.pulseaudio.org/ for more information on Pulse Audio.

Thank you for your answear. I ask you that because I have problems with my sound in debian, and I dont know what to do.
My sound card is creative and I see that in the Alsa page, it is supported, but when I install debian, my sound card isnot work good.
Is there a lot of noise and the microphone doesnot work.
I opened alsamixer and I see and try all type of configuration and nothing.
It doesnot work.
What can I do?
Reinstall Alsa?
Waiting for your help.

Would you please open a konsole, and run the command 'lspci' and post the results? I'm looking for the exact sound card you have. I know you said it is a Creative card, I'm sure there is more than one. There may well be specific problems with certain cards. It will probably take a little research to try and find an answer.

At this point removing and re-installing alsa will not do much. This is a windoze fix, rarely buys you much in a linux system.

Since you have some sound, I suspect you do have the correct driver installed. We need to find a fix for the poor sound you have.

Here are details for my sound card
Sound Blaster X-Fi Xtreme Audio
PCI\VEN_1102&DEV_0007&SUBSYS_10121102&REV_00\4&2966AB86&0&10A4

As I can see here, it is supporeted

Any help to reinstall ALSA?

It has limited support, yes. Many of the functions are not yet available from what I can find out. You do have sound, so the driver is working ( emu20k1 ).

At this point you have choices to make. 1. Live with it until an improved driver is released. 2. Buy another card that has better linux support. If you are going this way, make sure you look through the hardware compatibility list first, before you buy, and are disappointed, again.

After following several links, it appears the manufacturer is one that does not release information so a driver could be written for linux. This is not all that an uncommon situation. As a buyer, I avoid any company with this attitude.

Sorry I can not help more that this.

Thank you very much camorri
I will buy a new one if it is need some day.
But i want to ask you help me tow things more.

1. Please, tell me which are the manufacturer best supporeted by Linux, so I will have not problems in futures. Mey be Nvidia, Realtek, Atheros?

2. How can I know if some hardware is full supported or has some problem. becaise in this case, I see in Alsa page, that Sound Blaster Live appears as supported card here: http://www.alsa-project.org/main/ind...-Creative_Labs

So, how did you find out which one has perfect support and which one has worse support.

I will give you en example.
Please visit this page: http://www.openprinting.org/printer_list.cgi?make=HP
You can find there, for all manufactures if their prodicts are perfectly supported or Partially supported. How did you understund this for my sound card?

Can you tell me your experiens which hardware are best supported by linux?

A big clew to the level of support was this comment, right beside the driver.

Next thing I did was a google search on the driver emu20k1. I looked at several links, and read what others are asking, and people developing the driver code. I saw comments like, unable to find out what DMA channels the card uses.

I also did a search on the Alsa site for the driver, it leads to this -->http://www.alsa-project.org/main/ind...+emu20k1&go=Go

The link to openprinting is the best source of information on printer. Alsa is the best place for audio cards. You can always google, and see what other users are saying, and the type of problems they are having.

On this board, at the top of the page, you see a link marked HCL. ( Hardware compatibility list ). This is info our board members have contributed. It is a good source for audio card information.

Hope this helps.

Thank you for your time and wish to help.
