Subject: Can not rmmod snd_hda_codec_hdmi
Date: Tue, 23 Dec 2014 19:07:52 +0800	[thread overview]
Message-ID: <1419332872.4067.10.camel@xbing-ubuntu> (raw)

Hi community,

I am trying to implement the function of streaming SACD music over HDMI,
my PC is Intel Haswell based CPU (Intel i7 4770).

When I am trying to 'rmmod snd_hda_codec_hdmi', I get the prompt that
this module is in use (detailed message as below) 
rmmod: ERROR: Module snd_hda_codec_hdmi is in use

Is it possible that workqueue [hd-audio] is using this kernel module
(snd_hda_codec_hdmi)?

Can I use rmmod / insmod as the way to debug this module?

Thanks.
Xuebing Wang
