[alsa-devel] How to unload a sound module.

[Yiliang Bao]

Hi,

I am new to alsa driver development. The first problem I encountered is I
could not unload a module just inserted. I always get the following message
(using snd-dummy as an example).

> sudo rmmod snd-dummy
ERROR: Module snd_dummy is in use

I checked who is using snd-dummy. Here is what I got and I do not know what
applications are using it.

Module                  Size  Used by
snd_dummy               9600  2

Is there any easy way to unload the sound module?

Thanks,
Yiliang
