To further what Goeff said... I run Ubuntu 10.04 and yes - it does like swapping around sound cards. PCI can be hard coded, but with USB - even hard coded - I've found that it'll still from time to time swap around the values for no reason that I can find. Most of the time it works as expected, but every so often it doesn't. As a result I've just taken the view of avoiding USB audio cards for all but basic consumer use.
The other thing with Ubuntu - by default it has PulseAudio installed and enabled. Unless you have a reason to keep it around (in which case, you can jump through some hoops to make it work with JackAudio) then disable the thing - it'll only cause you grief (and if it is using your audio card(s), that may be why you can't get audio to play) To learn how to kill it, have a look at: http://rivendell.tryphon.org/wiki/Ubuntu_-_No_sound/sound_card_in_Rivendell_after_setup > > Hi Jason > I think most m-audio cards should work. > Ubuntu will probably know your sound card is there. > In a terminal type this. > cat /proc/asound/modules > > Sound Cards start at 0 and a second card would be card 1 etc > > You should get all your cards listed. > If the m-audio shows up there. > You might have to add lines for the second card in the /etc/asound.conf file. > for example... > pcm.rd1 { > type hw > card 1 > } > ctl.rd1 { > type hw > card 1 > } > > Now Ubuntu has a reputation for swapping cards around on subsequent > reboots.
