Ok. It does need to be listed as a card in /proc/asound/cards, just as a<br>
webcam with built in mike (although not a soundcard as such) will have a card<br>
entry and uses snd_usb_audio. So why isn't it there? </blockquote><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
Does it need firmware loading? I know some M-audio keyboards do. My Evolution<br>
keyboard doesn't, but someone with the same as yours will say.<br></blockquote><div>Nope. The very same keyboard was properly recognized with my previous setup (ubuntu 10.04). Plus it's USB class compliant.<br></div>

<br>
Have you tried it in a different USB slot if you have spare ones? Not in a<br>
hub as some USB things don't like hubs.<br></blockquote><div></div><div>I use the very same slot that I used on my previous setup.<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
The only other thing I can think of is that both the sound card and the<br>
keyboard are trying to grab card0 and the soundcard is winning, thus the<br>
keyboard can't use it. Now I've seen this the other way round due to the USB<br>
coming up early in the boot process and my keyboard grabbing card0 leaving no<br>
place for the actual soundcard. </blockquote><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

This is a very old problem, but may for some reason be happening in your case,<br>
so I suggest putting some index options in /etc/modprobe.d/options, which<br>
will at least confirm if that is the problem or not. See below.<br>
<br>
options snd_hda_intel index=0<br>
options snd_usb-audio index=1<br>
<br>
Best to reboot and then see if /proc/asound/cards lists both.<br>
<br></blockquote><div>Seems a good idea ! I'll try that. I might not be able to do it before tomorrow though...<br><br>Still it's strange that the keyboard does not appear in /proc/asound/cards<br><br>The other thing that strikes me is that on my previous setup after installing my soundcard drivers (Realtek ACL888), /proc/asound/cards listed 3 different ones : ACL888 anog, ACL888 digital and some kind of HDMI sound card.<br>
Here wiht my new setup, /proc/asound/cards only lists 1 sound card HDA intel but aplay -l lists the 3 i was telling you about above...<br><br>That doesn't seem right to me... :-/<br><br>Thanks a lot<br>jy<br><br> <br>
