Hi,
I recently purchased Focusrite Scarlett Solo and I found out that for my mic to work properly on both I need to remap the input to mono and therefore It will output the sound from L and right. (Right now It’s just on the left channel).
I know that I can do it in the application, but it would be much easier for me to somehow set it up in the system as this is my only input.
Is it possible to set it up in the PulseAudio config? (/etc/pulse/daemon.conf
or sudo nano /etc/pulse/default.pa
)
I’m using Manjaro Linux Kernel 5.7.17-2
$ pactl list short sinks
1 alsa_output.usb-Focusrite_Scarlett_Solo_USB_Y71B5UM0641B18-00.analog-stereo module-alsa-card.c s32le 2ch 192000Hz IDLE
2 alsa_output.pci-0000_00_1b.0.iec958-stereo module-alsa-card.c s16le 2ch 192000Hz IDLE
5 alsa_output.pci-0000_01_00.1.hdmi-stereo module-alsa-card.c s16le 2ch 192000Hz IDLE
Thanks for any help

But still no luck with load-module module-remap-sink sink_name=mono master=alsa_input.usb-Focusrite_Scarlett_Solo_USB_Y71B5UM0641B18-00.analog-stereo sink_given_by_previous_command channels=2 channel_map=mono,mono

UPDATE: I just now realized that sinks are for output and source for input. I changed my configuration and got new Remmaped Input which is now configured like this:
.nofail
load-module module-remap-source master=alsa_input.usb-Focusrite_Scarlett_Solo_USB_Y71B5UM0641B18-00.analog-stereo channels=2 master_channel_map=mono,mono channel_map=front-left,rear-left
set-default-source mono
But It does not produce any audio. I believe that I misconfigured something.

I finally found out the solution to my problem. It took me some time and I did some testing, but I believe this is the best option for me. I edited the config file like this:
.nofail
load-module module-remap-source master=alsa_input.usb-Focusrite_Scarlett_Solo_USB_Y71B5UM0541B18-00.analog-stereo master_channel_map=front-left,front-left channel_map=front-left,front-right
# set-default-source mono
I will edit this post when I find out how to make it default from config.
I posted this here because no one looks for the solution in the post.
