Yeti Pro suddently drops recording level

Hi. WASAPI will generally provide a lower latency than MME. It will also allow you to record audio being played back on your computer in case you need to do that.

not only the recording volume drops, by the quality of the recorded voice changes noticeably - it’s much thinner, almost echo-e, without that lovely bass cushioning.

Are you recording Stereo, two blue waves? A Yeti will do that. It’s a multi-capsule microphone and stereo is one of the options.

Your problem fails one of the Koz Tests. If somebody wrote me a really big check to force your machine to break, how would I do it? I can think of ways to make a Yeti sound like that, but not to have the effect come and go. None of these failures would reset when you restarted Audacity.

Describe your system. What kind of computer? Model numbers? What are your monitors?

Has the problem ever cleared by itself?

You can’t force it to break, right? It always happens by itself? Anything magic about it? It always fails after 3:35PM? Only on cloudy days? That’s a programming joke. Programmers have failures they call “Moon-Phase-Errors.” "When the humidity is over 65% and it’s a Thursday…


The current stable Audacity is 3.1.3. Which one do you have?



always in stereo

there is no pattern whatsoever - totally ad hoc - no identifiable triggers like the full moon or a bad mood of my cat (deceased)

potential cause - gremlins in my computer which come and go

it clears itself when restarting Audacity

I am much more concerned about this error

could someone reply please?

Error opening recording device. Error code: -9999 Unanticipated host error

Oddly, that helps.

That’s one version of the microphone losing good quality contact with Audacity. The sudden reduction in volume and bad sound quality is another. Audacity can do that when the connection to the microphone vanishes briefly.

Do you have another USB cable?

I did notice that the USB cable supplied with some microphones is longer than is good and healthy. As a fuzzy rule, 6 feet or 2M is maximum.

I think this is a “printer” cable, right? USB-A on one end and USB-B on the other.

This is where you find out that the cable on the bottom of the Yeti is loose.


what does a printer USB cable have to do with my Mic cable?

they are not the same.

I think that the USB ports on my PC are the issue as other cables plugged into other ports are wobbly - the ports are crap. they are not deep enough and not tight enough.

BTW how did you embed the image in the post? When I clicked on the picture icon it would only accept the URL.

It’s a .png graphic. Uncompressed screen grab picture file. First I heard of anybody not being able to view them.

The older printer cable is the one that the Yeti used. Square connector under the microphone and rectangular in the back of the computer. I think the newer Yeti’s used a mini under the microphone. This is the Yeti with the optional XLR analog cable, right?

That one is a .JPG. Can you view that one?

I think that the USB ports on my PC are the issue as other cables plugged into other ports are wobbly - the ports are crap.

That would do it. You’re describing a bad USB connection.


See here:

I didn’t say I can’t see your png image embedded in the post. Of course I can see it - or “view” it as you say.

I asked HOW you inserted it into the post.

When I click on the picture icon at the top of the editor, it allows me to only insert a URL of the image. It does not allow me to upload an image for it to be embedded directly in the post. So in order to give you a screenshot of my computer’s specs, I had to upload it as a picture to to get the URL for it (I didn’t want to use my website URL).

This however rendered the URL in the post, NOT the actual image. Only now I saw the ATTACHMENTS tab below, which I believe will render the image in the post.

My Yeti doesn’t have an old printer cable - that’s why I said that they are not the same. It has a mini plug under the mic.

I do know what an USB cable looks like, thank you.

Did I not answer that question? :confused:

sorry Steve there must have been a cross over between our respective posts.

I didn’t see your reply when replying to Koz.

From the manual (Error opening sound device - Audacity Manual)

-9999 Unanticipated host error: this means means “something is wrong”. And appears to most often be due to either:

  • A lost connection to a USB audio device.
  • Recent Windows / Mac update requiring that user gives permission for Audacity to access the microphone.

For an intermittent fault as you describe, the problem is very likely to be due to a lost USB connection.

Note that the connection only needs to be down for a fraction of a second to cause Audacity to loose the device. The computer will try to reconnect the device if the USB connection becomes available again, but even if successfully reconnected, the device will be allocated a different id by Windows, so Audacity will not be able to recognise it as the same device.

Common causes for lost USB connections:

  1. Faulty USB cable (common)
  2. Faulty USB connector (either end - fairly common)
  3. USB hubs (don’t use them for real time audio or video - usually OK for printers, keyboards, mice, other hardware that is not time critical)
  4. High CPU usage causing USB to be temporarily suspended (unlikely unless other apps are putting high demand on the CPU)

To avoid having to restart the computer, check the USB lead and connectors, then “Transport menu > Rescan Audio Devices”. This allows Audacity to look again for connected (and re-connected) audio devices.

Thanks Steve - that’s what I thought in the end.

I don’t need to shut down my PC, just save all my open projects and close Audacity then restart.

I will use the re scanning option from now on.

As I said in my reply to Koz - it looks like the USB points in my PC are crappy, as my other cables plugged in to other ports are also wobbly.

Come to think of it, USB ports are the weak point for HP, I had issues with them on my old HP PC too.

Looks like this is my last HP computer as they didn’t improve this or a number of other issues.

But this PC is still under warranty so I will ask them to fix this.



I got this error again, tried to re-scan - didn’t help.

still have to close all my projects and restart Audacity.

it’s a pain.

I will try to replace the cable.

I replaced the cable, re-scanned and it is working now.

But I have a different question.

My Yeti cable is I assume USB 2 as it is few years old.

I can use it when plugged in in either USB 2 or USB 3 port, but even when it is in USB 3, Audacity is still showing it as USB 2.

is it normal?

The device name shown in Audacity comes from the device driver.
I couldn’t find the relevant information in the Yeti manual, but the Yeti is probably a USB 2 device.

ok, thank you

The USB ports on both the HP laptops that I have are all fine and work well (also on my wife’s two HP laptops) :sunglasses:
