[linux-audio-user] how to make usb audio sit nicely with jack?

Hi: I set up my USB 2-channel audio interface (Event EZbus) this weekend. Amazingly, when I plugged it in, up comes this panel asking me if I wanted to configure it! I didn't expect to get even this much for something that had no driver! After a day of working with it, it came down to 2 choices: 1) I could have my usb audio interface working, but not at the same time as jack or any jack dependent programs that I had set up (such as zynaddsubfx, muse). Also, jack gives 'pcm' errors and then shuts down. 2) modify my /etc/modules.conf file to allow jack programs to work, and also my USB audio interface (but no tracking /dev/dsp device), but with awful cracking upon playback. I think I am having 'pcm' troubles, but am not sure. I am still trying to learning all of the modprobe commands. But I could really use some help on this. I feel like I am so close to kissing Macs goodbye if I can just get this to work. Below is my /etc/modules.conf file (I commented out any oss and rmmod-ed them). If I choose option 1 above I still get insmod errors at bootup, but all still works, except for jack as mentioned. I guess I should mention that there is currently a SBLive! card installed in a PCI slot also, but I am trying to bypass it and use only my USB device, even though I left it in its PCI slot on the motherboard. alias eth0 e100 alias usb-controller usb-uhci # --- BEGIN: Generated by ALSACONF, do not edit. --- # --- ALSACONF verion 1.0.1 --- alias char-major-116 snd alias snd-card-0 snd-usb-audio #alias sound-service-0-0 snd-mixer-oss #alias sound-service-0-1 snd-seq-oss #alias sound-service-0-3 snd-pcm-oss #alias sound-service-0-8 snd-seq-oss #alias sound-service-0-12 snd-pcm-oss add options -k snd-card-0 # --- END: Generated by ALSACONF, do not edit. --- alias sound-slot-0 emu10k1 post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L /etc/.aumixrc -S >/dev/null 2>&1 || : I would really be grateful for any help someone could give, Thanks in advance, gk
