routing channels

[slim]

Actually my question doesn't quite fit into any one forum as I tried HiFi
cable and Voice meter.

So I want to swap the ASIO channels that the PC audio is output on (1
& 2) to a ASIO device driver. I've tried both the HiFi cable and voice
meter and neither work.

1) HiFi Cable: when I change the input channels the channel meters
show PC audio on 3 and 4 but it's not changed on the physical device
driver. They stay at 1 & 2.
2) VoiceMeter - I cannot manually change the A2 channels. When I open
the settings dialog the second box is 4 and the 1st increments each
time I open the dialog. Clicking on either resets them both to -. I
assume they should increment on click?

The physical driver is for a McMillen K-Mix. It uses channels 1 &
2 for Mic and LoZ inputs so if I want to mix with PC audio I need it to be
on other channels - eg 3 & 4

I'm unable to find any other software that comes close to doing this
and while I used to do a lot of Win32 dev I've never attempted audio
drivers and don't really want to go down that rabbit hole.

Thanks

Hi. How many Inputs and Outputs does ASIO Bridge show you when you select your K-Mix as ASIO device?

You can check all the output channels of your ASIO driver using ASIO Driver Tester: viewtopic.php?p=4259&sid=7748915fc7b3d1 ... ea3f#p4259
Go to ASIO Device menu and select your ASIO device. By default it generates a Sinus wave at 440Hz that is sent to all output channels.

Thanks Adres - I'll find out. I didn't get an email notification so did not know your reply was here.

@andres I can't see how to paste an image here but i do get the expected 8 channels showing

The tester does produce noise on all 8 channels and showed my I had accidently muted 3 & 4 in the mixer - D'oh. PC sound out on 3 & 4 works perfectly. Whoop!

FYI 10% callback error just keeps incrementing

So a couple of strange things I noted. I'm routing PC main sound output to HiFi Cable (ie speaker icon in tray) but sound is coming from Plex app running in Firefox

* I get no sound unless ASIO Bridge is running - I did not expect that
* The master volume control does nothing put the Plex app does
* If I switch source back to K-mix driver then Firefox errors
* I need to close ASIO Bridge for sound to revert ot KMix driver, sometimes also need to restart Firefox

Anyway I have a useable solution - thanks for being the ONLY solution

Hi. You could try to set this up using Voicemeeter Banana (Potato also supports this):

• Select the ASIO option for your K-Mix from A1 Hardware Out selection list.
• Set the Windows Default Output device to Voicemeter Input (VB-Audio VoiceMeeter VAIO). Use for example the Speaker icon in the notification area.
• Route the Voicemeeter VAIO virtual input to the K-Mix using the ►A1 button
• Change the routing mode to Composite for the A1 bus under MASTER SECTION
• Open Voicemeeter System Settings / Options... window.
• Under PATCH COMPOSITE section, select IN#4 Left and IN#4 Right in the third and fourth box respectively. Select an unused channel for the others.

Please let us know if this could be an option for you and if you need further assistance.

I'm all sorted using HiFi Cable, thanks. Sorry of that was not clear form my previous answer.

How do you post images? I can't see it anywhere?

Thanks for a very useful product
