I have laptop speakers but I don't want to use those; I want to use the speakers connected to my USB port. How can I make my Kanotix use that and not the laptop speakers?

Most easy way would be to blacklist die "normal" module or you disable onboard sound in BIOS.

I have never blacklisted the onboard sound (but that's a great idea) but use Philips external USB speakers when I visit my parents. I just plug it in and set alsa to hw:1,0 (either in kcontrol or in the apps). Most of the time they are recognized at such.

Blacklisting:
as root edit /etc/modprobe.d/blacklist and add
Zitat:
blacklist snd-whatever


Easy way as root in the shell:
Code:
echo blacklist snd-whatever >> /etc/modprobe.d/blacklist

snd-whatever has to be replaced by the name of your sound-module. You can list your modules with
Code:
lsmod | grep snd
If you do not know what the output means, post it here.

The sound doesn't work at all now. The USB powered speakers are green lighted which means they are on and operating. Maybe Kanotix is not detecting them? I am using Enlightenment DR16 by the way

First two things I would check:

1. alsa hardware setting (xmms does it nicely, gives you the hardware address in alsa-plugin configuration)
2. alsamixer setting. Maybe you have to mute or unmute sth.

You can also check
Code:
lsusb
if your speakers are recognized at all by the USB-system.

You need to use an editor to edit the file. Not sure what editor you have available so I'll use xedit as an example:
Code:
$ su
# xedit /etc/modprobe.d/blacklist


I like an small editor called leafpad but you can use any editor you like.
Code:
# apt-get install leafpad


Zitat:

CTRL+D
OR
Code:
exit

Oops

How do I log into root from the login screen? I can only see my name 'SentralOrigin' and no option to log in as root as when I had 2005-4

I tried to edit and then save but I get this error:

The document could not be saved, as it was not possible to write to file:///etc/modprobe.d/blacklist.
Check that you have write access to this file or that enough disk space is available.

I think it's because I'm not logged in as root. How can I log in to root? I don't have the option to because I only have one option to log in as "SentralOrigin"

Do blacklisting like that:
Code:
echo blacklist snd_intel8x0 >> /etc/modprobe.d/blacklist
After that it is blacklisted, you wrote a line into a textfile.



To undo the blacklisting, open the file through the console as root like that (there are two ways, chose one of them:
Code:
# mcedit /etc/modprobe.d/blacklist
# vim /etc/modprobe.d/blacklist


If you are more familiar with gui-editors (I suppose so) become root the following way:
Code:
sux
[password]
kedit /etc/modprobe.d/blacklist


Then you can either delete the line or you just comment that line with # plus SPACE. So it might look like that:
Zitat:
# blacklist snd_intel8x0


Btw, you cannot start the file blacklist in a shell just by typing it's path, it is a text-file.

Well logging into Xwindows as root is not a good idea nor is it necessary. Just use a terminal, get root and edit your file from there.
Code:
$ su
# xedit /etc/modprobe.d/blacklist


Note the $ indicates you are USER
the # indicates that you are ROOT

Thank you sir that fixed all my problems EXCEPT the sound problem :p

Okay I can't block the mainboard sound from BIOS, but I got the blacklisting correctly so the sound doesn't come out anymore.

But now the sound won't come out at all. How can I make it recognize my USB speakers now?

It seems as if my box recognizes the USB as speakers and it knows that it can play audio through it, but it just doesn't want to because it thinks it can't play audio? or something LOL

Any suggestions on how to make it play through my USB? I'm running on Enlightenment DR16, by the way. When I try to play music through XMMS it says sound is not detected but when I check the settings it knows that the USB speakers are there and I can change the volume on the thing and in the XMMS (but it does it both at the same time) so I dunno
Please help
Thank you very much for all the help so far

Here is Kanotix, not Delphix Mr. Green

Sometimes a reboot is the quickest way. My cheapo external USB soundcard here needs a reboot and is recognised then by the default settings. xmms does not love it, kde-progs love it.

My USB-speakers at my parent's place are more sophisticated, they can be set to work how I want. And that's the easiest way:
Do you have xmms installed. If yes, open it and look at the list of devices for the alsa-plugin. That's quite handy.

Look at this pic:
http://img508.imageshack.us/img508/6852/xmmsjd9.png

It's the alsa-output-plugin configuration in the xmms options, and there you can see hw:0,0. That is the address for alsa you need to set. In this case, it is my cheapo external soundcard, it runs through default pcm, which yours obviously does not, your default is the internal speakers.

By having got that address, you just adjust all your outputs to alsa with that address. How to teach E DR16 that it uses alsa only, I do not have the slightest idea, I do not know that DE. So try it with xmms first or with any other multimedia software.

You can also try to reload alsa as root in the shell (don't type the #, it inidcates you should be root):
Code:
# /etc/init.d/alsa reload


So you can do:
1. check xmms for address
2. reboot
3. reload alsa

If then there is still no sound, I am out of ideas Mr. Green

Greetings
hubi

Alright, some cheapo USB as well obviously (cheap does not mean automatically the price you pay :-/).

Ok, same problem here, I was never able to convince xmms to play sth. All KDE-stuff works perfectly.

But you have the address. Try other players with that hardware-adress (hw:x,x).

It's obviously a hardware thing, my Philips-Speakers are plug and play. With every application and with every player, and they can play sound simultaniously from various sources. With my cheapo here I can't do those funny things.

Damnit it still doesn't play

In the Alsa config, should I box off the "Use software volume control"? I don't know what that does. It still won't play any sound, even when I removed the blacklist from the mainboard lol. But I set it to play as the hw 0,0 USB device. Damnit

I just unplugged my USB speakers and I plugged them back in and now they won't even turn on

Do I need to mount the USB drive maybe?

I just tried playing music in Kaffeine or whatever and I got the error:

xine
failed to initialize all audio drivers

Or something along the lines of that

The address should be hw:0,0

Or was it a typo?

Ah! I know that one.

Keep xine, set device to automatic. If that works, reset it to alsa. And if that works, keep it.

None of my speakers/soundcards which are USB love being unplugged. I usually reboot then, just because I don't know how to get the modules back. Quite dumb those things. Mounting does not help, they are no filesystems.

What make/model/brand of USB speakers? I've never owned any USB speakers myself but Google might know something about them.
