Can you get it work with jack or portaudio? Does sr=48000 make any change? Some linux drivers support just one sample rate and other software somehow might not be so specific about it.

sr=48000 does not work either, nor does changing the bit depth.
it might be the point to go into jack. are there good information on the
jack homepage, or where can i start?
thanks -

Is there a hardware switch on the card for selecting sample rates? My
edirol card has an actual switch that I need to make sure is in the
correct position for it to work on Ubuntu. Perhaps the EMU card has a
similar feature?

no, but i suspect it's another problem than the sample rate. it's just a
little bit odd that pd and audacity do not complain in any way.

hi,

yes, then try to get jack work and you can make csound connect to  jack then.

if you don't have jackd installed already, you need to get jackd and qjackctl (frontend)

and if necessary (although maybe not in newer systems)
follow instructions for example on   https://help.ubuntu.com/community/Ubuntu%20Studio%20Upgrade%20from%20Ubuntu   :
- add the user to group audio 
- add lines to file /etc/security/limits.conf 

@audio - rtprio 99
@audio - nice -19
@audio - memlock unlimited

try to start jack with qjackctl, perhaps with you internal sound card at first to see if jack works and the the usb sound card.

I found from page http://www.alsa-project.org/main/index.php/Matrix:Vendor-Creative_Labs
that "E-MU 0202 USB   44/16 playback and recording works on Ubuntu 10.10 with ALSA 1.0.23"

so thre should be hope.

Or, try if you can configure the sound card to work with gengeric snd_usb_audio driver.

About PD and audacity - interesting how they comunicate with the sound card, do they use directly alsa or they have pulseaudio in between or something else? What are the settings in Audacity -> Prefernces that make it work?

Hopefully you will have luck!

tarmo

i got it working with alsa. the trick was to select the emu as default
device in the system preferences, and then simply call csound with -iadc
and -odac (without specifying the device). thanks to all for the tips; i
will check out jack later.
