Re: [LAU] Fireface UCX

Hi, I use the ff ucx via USB. As far as I know, it is not possible to use it via firewire. I getting reasonable sound results using the usb class compliance mode, you have to make sure that this mode is enabled on the device (it is NOT by default). The ALSA driver then recognizes the device. If you enter aplay -l in a terminal, you get a list with all devices available to alsa. If it does not appear there, try the comand dmesg to look for error messages of the alsa kernel module. If I do that, I find a message usbcore: registered new interface driver snd-usb-audio indicating that the interface is working. Then, the device is available in pulse-audio and also jack, you can choose it there. I should add the following: My system (and in particular the alsa kernel module) is not up to date. I am still using an old customized version, where I fixed a bug by hand (getting help from the alsa list). As far as I remember, this bug was fixed so that the device should work with the standard alsa kernel module. However, I never tested it, maybe I find time to do that during the weekend.
