I'm trying to use MSO and I realize that my measurements need a timing reference.


UMIK-1 USB Microphone
Win 7 Computer with latest drivers
HDMI connection to AVR

In the computer, I can set it to 7.1 and sent a test tone to each speaker in the system.

However, when I go to REW Preferences, I can only see the High Def Audio on the Java side, not on the ASIO. So, it doesn't look like I can select anything other than Left/Right/Both.

So, with that in mind, how can I get a timing reference?

Thanks,
Scott

Are you using ASIO4All? If so, sounds like it may not be configured correctly to show the available devices. The guide here has detailed instructions.

When I click on ASIO, I see the MiniDSP 2x4 HD but that's all.

I'm not using the ASIO4ALL but if it's known to work, I'll give it a try. I was under the impression that it had issues.

The HDMI interface typically will not come with an ASIO driver, and the Java driver on Windows doesn't support multi-channel access to the device. ASIO4All wraps the Windows driver to create an ASIO driver that exposes all the channels.

I've got AISO4ALL v2 running.

Some differences that I see when I switch Preferences/Soundcard to the ASIO side:

Input - The option is see is 3: USB Audio Input 1, don't see the UMIK-1 listing.

In the ASIO Control Panel, I see:

Realtek High Definition Audio
UMIK-1

They are enabled as per the tutorial, but I don't have a line that says "HDMI Audio".

When I try to run the Check Levels, I get the pink noise coming out of the computer speaker for a second and then a pop-up message:

ASIO device has been reset due to:
Reset Request from driver
Inputs and outputs may need to be re-selected

I'm assuming that I need to find the "HDMI Audio" driver/setting. Any tips?

This computer is pretty old, I could haul a desktop in here if I have to. It's running Windows 10.

Is your HDMI plugged into your AVR and is that HDMI input selected on the AVR? The audio device may not be present unless there is a live connection. Beyond that I'd revert to that guide and the related thread, I haven't used an HDMI output for measurement myself.

Yes, it shows up in the Java side as Sharp HDMI-1.

Then I switch to the ASIO menu and pick ASIO4ALL v2. The MiniDSP and Realtek ASIO drivers show up in the list also.

So, I found an Nvidia driver and updated it. Now I have another item on the ASIO Control Panel called "Nvidia High Definition Audio". I enabled it but I still got an error when I tried to play Check Levels.

But, I restarted everything and it worked! Thanks for the responses.

Back to measurements.
