view story

http://ubuntuforums.org – Hi everyone I'm new in the ubuntu studio scene, and I've been loving every second of the experience so far. However I'm having an issue trying to use my soundblaster x-fi 5.1 over alsa using the 64bit - low latency version. over pulse audio is working just fine. I pretend to use this system to record music, combining a vox tonelab valvetronix multieffect console connected thru usb, I can see it works right now on the mixer, no problem with that so far, but no sound over alsa :( I can see that the system recognizes the card as a usb-audio but only gives me option to turn the led on and off.
