snd_pcm_plugin_set

Enable PCM plugins

Synopsis:

#include <sys/asoundlib.h>

unsigned int snd_pcm_plugin_set_enable( snd_pcm_t   *pcm,
                                        unsigned int plugins );

Arguments:

pcm: The handle for the PCM device, which you must have opened by calling snd_pcm_open_name(), snd_pcm_open(), or snd_pcm_open_preferred().
plugins: A bitmap of the plugins that you want to enable.

Library:

libasound.so

Use the -l asound option with qcc to link against this library.

Description:

You can use snd_pcm_plugin_set_enable() to enable plugins that aren't ordinarily used in the plugin chain. You need to do this before calling snd_pcm_plugin_params().

Returns:

The updated bitmap of disabled plugins.

Note: This function doesn't return a negative error code the way that other snd_pcm_*() functions do.

Caveats:

This function isn't thread safe if pcm (snd_pcm_t) is used across multiple threads.
