rmmod snd-hda-intel first.

Clemens, thanks for your help.

I am using Fedora 21 (Ubuntu 14.04.1 has the same problem).

'rmmod snd-hda-intel' shows this module is in use too.

'modinfo snd-hda-intel', nor file /lib/modules/.../modules.dep shows that any kernel modules depends on snd-hda-intel or snd_hda_codec_hdmi.

Is it possible that a kernel thread is using these 2 modules?

Any ideas? Thanks.

Run this to see if some userspace process is using the ALSA devices: fuser -v /dev/snd/*
