Hmm, it looks like Input working is the result of my addition to 
alsa-kernel/usb/usbquirks.h
Recording from mic now works (on very low volume though)

/* Creative X-Fi Notebook */
{
     .match_flags = USB_DEVICE_ID_MATCH_VENDOR | 
USB_DEVICE_ID_MATCH_PRODUCT,
     .idVendor = 0x041e,
     .idProduct = 0x30d2,
     .bInterfaceClass = USB_CLASS_AUDIO,
     .driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) {
         .vendor_name = "Creative Labs",
         .product_name = "X-Fi Notebook",
         .ifnum = QUIRK_NO_INTERFACE
     }
},

I tested some other quirk values but nothing else works at all. As for 
output - alsamixer actually shows it and allows to change it's volume, 
but channel number is not available. For example speaker-test says 
'Error setting hwparams: Invalid argument" and aplay says "Channel 
number is not available" on any channel number.
alsa-info output is attached.
I ask for any help from experienced alsa developer (snd_usb_audio 
specifically).
