In above video switch to audio track 2 and you can see the throughput audio in the VAIO input and output, you'll notice audio is muffled, starting Voicemeeter causes the issue (VAIO as output, start audio engine) but the audio feedback volume is significantly lowered, fixing the feedback issue (speakers output, restarting audio engine) removes all feedback.
OK. This kind of sound sorce is special as ist is most likely 7.1 Surround. If you directly output to the Realtek driver, you get all channels there and whatever "sound processing / headphone simulation /3D Sound / Dolby" is configured to enhance it.
If you feed it into VoiceMeeter, the default configuration is "normal mode" for each channel (the light blue text with the two rows of dots below on top of the master output channels). This picks just the left and right channel for processing and only feeds this two into the headphone. You either want to select one of the "Mix down" settings to get 8 channels into two earbuds or you configure it as "multi channel" to feed all channels through to the sound chip. Just click several times on the button to change modes.
However, VoiceMeeter output "to Realtek" means
direct output to the sound chip
without any further processing. Especially when using ASIO. This essentially cuts you from all sound enhancement gadgets you might have installed. This is due to the idea of ultra low latency. ASIO was primary created for music production and processing. Any audio processing would have to be done the DAW/Audio Mixing way by utilizing "effect inserts" with DAW compatible Plugins (VST plugins) WITHIN the DAW. Lacking a DAW, VoiceMeeter offers you such a "insert" channel for each input.
The "muffling" you notice might just be turning off all sound enhancements by the driver you are used to.
MicMute 01
This is to expected, as the default configuration of the VoiceMeeter integrated recorder is "Pre-Fader, Physical Inputs". Mind the red "Input" sign on the cassette. "pre-fader" is to be considered verbally. it records the signal that the device is generating BEFORE it enters the VoiceMeeter processing. Thus muting has no effect on the Mic Strip, nor is the fader of any use her. Hence "pre-fader".
This is the optimal setting for multi channel music production as you can save the raw signal from each channel before it gets garbled by any further processing step. You always can change your mind and mix them differently later on in the DAW if you keep them clean and separate.
If you want to save the final mix, go to "post-fader" or use a different software to capture the audio mix on B2 maybe.
You might want to change this behaviour to "BUS, post-fader". This way you can select whatever your mix does deliver in one of the physical or virtual busses "A1 - B3".
Right click on the cassette to get to the configuration. Check the documentation about the multiple optiuons here.
MicMute 02
I see you are feeding the true signal from the Mic (most left channel) only to Bus B1 virtual output. This is the one you configured in the other software as "Voicemeeter Vaio" (Voicemeeter Output). This way I would assume it gets fed through to the partner but not into your headphones. You do NOT hear yourself speeking in the headset. If you want to hear yourself, you would have to select output A1 (the Realtek chip) to listen
on the Mic strip too. But usually this is distracting as there is some small lag involved.
If you STILL can hear yourself speaking, then the App echoes the (virtual) Mic back to the (virtual) output where it gets fed into VoiceMeeter again, together with the background sound on channel on the strip you named "System". It then is further processed as if generated by the software.
Muting the Mic
does work as you can see virtual B1 drops to zero when doing so. No more Mic in the App.
You are showing the Hardware Out A1 that mutes when you mute The virtual Input channel "System". This is to expected, since this one is the only one that connects to A1 (which is mapped to the Realtek and thus headphones). And since it is mapped to B2 too, this meeter follows the same.
I assume you have some recording or other secondary signal processing on B2 and thus the software set to listen to "Voicemeeter AUX". This way you just get the sound from "System" and never the Sound of "Mic" as nothing but the system is configured to send audio to B2.
If I have to guess, you have the in-game voice configured for output "Voicemeeter In
AUX" which is the middle of the virtual input strips. This one is routed to A1 so you should hear it. It does
not get to B2 so you will not get this recorded. If you just use the internal recorder, it is not recorded either, as I can see there is only the first dot active in the red "input" sign of the cassette. If you want to record any of the virtual inputs too, activate the B1,B2 in the recorder dialog (right click). The signal gets down mixed to Stereo for recording, so be warned. Since these are pre-fader to, the mix balance has to be made elsewhere
before the signal enters VoiceMeeter. Or switch to "post-fader".
So it now depends. If your Game has an option to echo the mic to the headphones - turn it OFF. Instead activate A1 on the Mic strip in VoiceMeeter. This greatly reduces the lag you may experience hearing yourself. If you don't want to hear you talking IN the headphones, sitll turn the Mic echo OFF in the game. You must make sure the receiving software does not loop your Mic signal back to the "speaker" as THIS is the feedback you are looking for.
If you can't you instead have to make sure the Mic Strip is never connected to A1 to avoid echo
If you get Mic signal into the headphones there is always a chance the sensible mic can pick up spilled signal from the headphones causing an acustical loopback.
To tell it easy:
- configure everything you want in the recording (externally) to output to "B2"
- to use the internal recorder either choose any of the "pre-fader inputs" (default) or use one of the output strips as recording source = "post fader".
- configure everything that yau want to hear in the headphone to go to "A1"
- Configure everything you want to send over to the Game to go to "B1"
- you MAY configure external audio sources to either of the three "virtual Input" channels if you want to mix them separetely or just all together into one if they should be treated the same anyway. Your choice.
