The interface association descriptor should have been provided by the firmware.

Anyway, try the following quirk:

{
	USB_DEVICE(0x1cc5, 0x000f),
	.driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) {
		.ifnum = QUIRK_ANY_INTERFACE,
		.type = QUIRK_COMPOSITE,
		.data = (const struct snd_usb_audio_quirk[]) {
			{
				.ifnum = 1,
				.type = QUIRK_AUDIO_STANDARD_INTERFACE
			},
			{
				.ifnum = 2,
				.type = QUIRK_AUDIO_STANDARD_INTERFACE
			},
			{
				.ifnum = -1,
			}
		}
	}
},
