No audio for middle/center/subwoofer, muted by default for Creative X-Fi 20k1 chip

[death]

With X.1 surround configurations only middle/center/subwoofer channel is muted by default. All other channels are ok. I need unmute with alsamixer.

For Ubuntu 20.04 or any distro:

I confirm that Middle/center/Subwoofer is working, when add this(Because for my card, center channel is not called Center, LFE or CLFE like other cards, but it's Center/LFE instead):

[Element Center/LFE]
switch = mute
volume = merge
override-map.1 = center,lfe

To the /usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf

The card is Auzentech Auzen X-Fi Prelude 7.1 with Creative X-Fi 20k1 chip

With this solution, there is no need to unmute middle channel. All channels have sound without edit alsamixer in terminal.
