Fireface 800 modprobe issue

[brittyazel]

Hello,

My lab has a fireface 800 that we use for very timing sensitive audio output. We are using Ubuntu 17.04, Linux 4.10, and I downloaded your repository and followed the steps to install the modules via DKMS. The install is successfull, but when I execute "sudo modprobe snd-fireface" I get an error saying that it cannot find "amdtp_stream_pcm_ack" (I don't know the exact error, as I am not at that computer at the moment).

Any idea what I can do to get this error resolved so that I can use alsa for my fireface 800?

You might see below warnings when executing dkms command line.

snd-fireface.ko: Running module version sanity check. Error! Module version 03F360D12AF05E4AD74EDD4 for snd-fireface.ko is not newer than what is already found in kernel 4.12.0-rc2-falcot (3421437241FDEA8742A9C82). You may override by specifying --force.

By following to the guidance, please add '--force' option to the command line.

That isn't the problem. I can execute the dkms comand line fine, and I do see those errors, but the issue is when I actually try to load the snd-fireface module. It throws an unsatisfied reference to "amdtp_stream_pcm_ack" and says check my dmesg for details

You encounter symbol mismatch between snd-firewire-lib and your snd-fireface. Please follow the above guidance.

Yes, it is still not working.

nvm rebooting seemed to fix it

You might have missed to unload relevant modules, before replacing modules by dkms.
