Has anybody been able to use creative xmod usb sound card?, I am having a tough time trying to make it work. It recognizes it if you plug/unplug it, even the volume buttom works (in the sense that the applet shows the master going up or down, to the other sound card) but if you try to use it with say, aplay -d Xmod song.ogg, it will not work.

Following the instructions in
/usr/share/doc/alsa-base/README.Debian.gz

I added a line to my /etc/modprobe.d/sound which now looks like this

alias snd-card-0 snd-hda-intel
options snd-hda-intel index=0
alias snd-card-1*** snd-usb-audio
options snd-usb-audio index=1

since after pluging it it shows as follows

arc@tosh:~$ cat /proc/asound/cards
*0 [Intel********* ]: HDA-Intel - HDA Intel
********************* HDA Intel at 0xfc500000 irq 22
*1 [Xmod********** ]: USB-Audio - Creative
Xmod
********************* Creative Technology Ltd Creative Xmod at usb-0000:00:1d.2-2, full speed

or

arc@tosh:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC268 Analog [ALC268 Analog]
* Subdevices: 1/1
* Subdevice #0: subdevice #0
card 1: Xmod [Creative Xmod], device 0: USB Audio [USB Audio]
* Subdevices: 1/1
* Subdevice #0: subdevice #0

However, this is what I get now, same as before:

arc@tosh:~/música/JoanManuelSerrat$ alsaplayer -d Xmod Benito.ogg

=============================

Is the conclusion at
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=491196
right, or am I doind
something wrong?

Any ideas? Thanks in advance.

That looks good to me.

You have to use "aplay -L" (which is the same as "aplay --list-pcms") to
get a list of the known PCM names.

I think you are using the wrong device string; AFAIK, it has be a known
PCM name (see above). For example, on my system the correct alsaplayer
device string of the built-in Intel sound card is "default:CARD=Intel";
"Intel" or "HDA Intel" do not work.

Thank you Florian, that was the whole problem! Now I have both working (I left xmod as default)
aplay -L was the key to determine the correct name.
alsaplayer -d "default:CARD=Xmod" file.ogg
works.
Now I have to solve the volume button issue, which is not properly controlled.
