Thanks.

I uploaed the file pipewire.zip to;

  https://drive.google.com/file/d/1-Lm6dtGy9DDIPmZzRuR4TFhMqq84BLoq/view?usp=s...

This includes;

     1. 10-rates.conf
     2. 20-virtual-pipe-source.conf
     3. custom.conf
     4. sink-reverb-7_1.conf

where;

     1.	10-rates.conf	- Automatic sampling rate setting File

	  You can see the sampling rate with playing any sound as
	  follows;

	     $ cat /proc/asound/card0/pcm0p/sub0/hw_params

     2. 20-virtual-pipe-source.conf

          This will create a playback stream linked to the configured sink.
	  When you write samples to /tmp/virtualdevice they will be
	  played on the sink.

           Cf. https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Virtual-Devices#pip...

     3. custom.conf

          This is the user customization file.
	  In my case,

             node.latency           = 1024/384000 ## 384000; sampling rate

	   Set the quantum value by referring to the following site;

             https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Configuration?versi...

    4. Reverb file

       This files requires
       lv2-dragonfly-reverb-3.2.10-1.43.x86_64.rpm.

       I added a gain variable so that you can control the
       loudness. For example, to make the bass louder, you can do the
       following.

       { type = lv2 label = mixer name = mixLFE control = { “Gain = 0.125” }}

       ↓

       { type = lv2 label = mixer name = mixLFE control = { “Gain = 0.500” }}

Install pipewire.zip as follows;

       1. $ rm -rf ~/.config/pipewire
       2. $ unzip -d ~/.config pipewire.zip

    That is, ~/.config/pipewire/pipewire.conf.d is the correct
    customization folder.

Just to be sure.

1. Environment variables required for using pipewire;

   PIPEWIRE_MODULE_DIR=/usr/lib/pipewire-0.3:/usr/lib64/pipewire-0.3
   SPA_SUPPORT_LIB=/usr/lib/spa-0.2/support:/usr/lib64/spa-0.2/support
   SPA_PLUGIN_DIR=/usr/lib/spa-0.2:/usr/lib64/spa-0.2
   LADSPA_PATH=/usr/lib64/ladspa
   LIBJACK_PATH=/usr/lib64

Sorry, but please ignore 11-channelmix-upmix.conf in the zip file.

Best Regards.
