[SOLVED] Sound Blaster Katana ALSA Microphone

I'm trying to figure out how to configure Sound Blaster Katana microphone. Unfortunately, pavucontrol never displays any capture effect on its bar. Alsmixer has microphone at 100 and capturing. In output device unmute of microphone makes is correctly heard as an output. During recording mic-in is always silent:

Setting 

load module module-alsa-source device=hw:2,0

before

.ifexists module-udev-detect.so

doesn't help.

Setting 

load-module module-remap-source master=alsa_input.usb-Creative_Technology_Ltd_Sound_BlasterX_Katana_8C48A0C3FE2950FCA0-00.analog-stereo channels=2 channel_map=mono,mono

doesn't help.

The ending of ALSA CARD name change depending on pavucontrol profil, but non of profiles provide a working mic-in.

Thank you for your help! I'm out of ideas.

Re: [SOLVED] Sound Blaster Katana ALSA Microphone

Post a proper amixer -c2, simple amixer will show the pulse plugin compatibility mixer, which doesn't reflect real hardware state.

Also repost 

pacmd list-sources
pacmd list-source-outputs
sudo fuser -v /dev/snd/*

during an actual recording attempt

Just from the screenshot you are feeding from your output monitor, you will want to select the mic in the dropdown.

Regarding "Just from the screenshot you are feeding from your output monitor, you will want to select the mic in the dropdown." it was a mistake as I've experimented with every single option. Thank you for your feedback!

Re: [SOLVED] Sound Blaster Katana ALSA Microphone

It's likely that 

amixer -c2 set 'PCM Capture Source',0  'External Mic'

will suffice.

Thank you @V1del! I've learned more about amixer thanks to you.

Re: [SOLVED] Sound Blaster Katana ALSA Microphone

Yes it's somewhat unfortunate that many of these little 'custom' knobs are not being visibly exposed by pulseaudio. It often helps to check actual hardware controls with alsamixer/amixer. Technically with this information we could define an appropriate pulseaudio path file that will flip this switch when the microphone profile is selected, but these have a specific syntax that I'd have to get back into. And if you don't often flip around between the two modes this should stick for the entirety of your usage, so it might not be worth the effort (also seeing that pulse does provide this functionality natively anyway regardless of hardware support for it)
