You still need some entries in modules.conf and to install the alsa-lib and alsa-utils packages. These things are exactly the same as in 2.2/2.4, so you probably already have them. If not, have a look at the ALSA website. Your modules.conf entries would look somewhat like this: options snd cards_limit=2 alias snd-card-0 snd-intel8x0 options snd-intel8x0 index=0 alias snd-card-1 snd-usb-audio options snd-usb-audio index=1 # maybe third entry if the mainboard has a MIDI/game port # OSS emulation entries omitted It may be possible that your hotplug scripts try to load the OSS driver (usb-midi) for the keyboard. In this case, add usb-midi to the /etc/hotplug/blacklist file. > 2) Where can I expect my devices to show up? For now I have an onboard > soundcard (i810) and the Evolution keyboard.

ALSA devices are accessed through the ALSA library. Audio devices have names like "hw:0,0" or "plughw:0,0" (the numbers are card and device numbers). For a list of devices, run "aplay -l" or "arecord -l". MIDI sequencer ports have names like "72:0" (client and port number). For a list of ports, run "aconnect -io". > 3) I noticed somethiing jack showing up. This is probably the usb-midi driver. These messages tell you about the presence of MIDI jacks, and aren't related to the Jack Audio Connection Kit. > Is jack supported? If so, to what extend? Yes. Just like in other kernel versions.
