Please check your kernel configuration, like: $ grep SND_ICE /boot/config-4.4.1-040401-generic CONFIG_SND_ICE1724=m You cannot see CONFIG_SND_ICE1712. This means that snd-ice1712 is not built for your kernel. I don't know the reason, but for your information: Collateral damage due to kernel configuration change enabling CONFIG_ZONE_DEVICE (Kernel 4.4 amd64) https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1534647 Regards Takashi Sakamoto ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
