InternalPortAudio error since windows 10 update

fletch2099 · July 30, 2015, 6:22am

Hi

I use audacity since a long time now, and it always worked very well. I even used it to mix music and it’s an amazing software.
I know windows 10 is not supported yet but in case of someone has a trick to help me, I wanted to post my problem here (finger crossed),

Since I updated to windows 10 pro(from windows 7), no audio devices are recognized.

-I can record with orther programs like obs
-I’ve checked that my device is activated in windows sound control pannel
-I tried to reinstall chipset/audio driver for my manufacturer (asus)
-I’ve uninstalled audacity, deleted all the remaining files and downloaded a portable version to be sure no old files could interfere
-When I launch audacity I got a message box InternalPortAudio error
-In Audacity preferences Devices/interface everything is blank
-I really don’t know what to do now to fix this

Thank you very much for your help

When you say you reinstalled the Asus drivers were those Windows 7 drivers? Have you been to http://support.asus.com/download/options.aspx?SLanguage=en&type=1 and checked if ASUS have listed Windows 10 audio drivers for your computer model?

If they are providing Windows 10 audio drivers, install those. If not, then you could try going into Windows Device Manager and rolling back to the standard Windows (Microsoft-provided) audio drivers, though you may lose some functionality.

If you are now using Audacity Portable from PortableApps.com please note that is not our project and we cannot offer you support with that. Audacity supplied by us is available at http://audacityteam.org/download/windows.

I confirm that I’ve installed windows 10 audio drivers, and I have 2 sounds cards (one asus xonar and the realtek included in my motherboard)
plud I have a blue yeti mic and a webcam but the problem is that all the fields are blank and I cannot select anything as in device or interface in audacity and it’s working with obs or with windows
I downloaded the portable version to do some tests (I took it on your website, it’s the zip file version), but I use the last version of audacity available on your website, the one with the installer

Thank you for your help

There may not be much you can do except for changing drivers such as rolling back to the default Windows drivers (or to some previous driver set). In the current absence of Windows 10 audio drivers for my laptop, I’m using the Windows 7 audio drivers in Windows 10 - Audacity recognises those drivers but not those for Windows 8.1.

Have you tried disconnecting Yeti and the web cam, then disabling Xonar in Device Manager then restarting Audacity? You could also enable Xonar but disable Realtek. It’s just a guess but it could be that if Audacity fails on one device it’s giving up on the others - it should not happen but this is a new version of Windows.

You could post your dxdiag report as well, but there is no guarantee it will help. Just click the search icon and type “dxdiag” (without the quotes).

I forgot to say that I even reinstalled the chipsets motherboard drivers.

I saw somewehre in the forum (I don’t remmerber where) that an older 2.X beta version of audacity worked in windows 10, can you confirm that?

Thank you again for your help, I’m agree to try anything to make It work, I really enjoy audacity and I don’t want to use another program

here’s the dxdiag report concerning the sound:

fletch2099 · July 31, 2015, 7:48am

another reply (the last one, sorry for that ) I’ve installed the 2.0.2 version and everything is working now, I assume there is a problem with the 2.1.1 on some windows 10 systems.

Gale_Andrews · July 31, 2015, 5:26pm

2.x versions are not betas, and no-one other than you has reported that 2.0.2 does not have the Windows 10 PortAudio initialisation error, but thanks for posting your finding and for the dxdiag report (which looks fine).

A few users find that versions of Audacity after 2.0.2 reset the audio output balance to equal, but that isn’t specific to Windows 10.

Gale

sokoban · August 1, 2015, 1:05pm

In my case, under W10, I can use up to v2.0.3 without problem.
All other later versions give the annoying “InternalPortAudio error”.

sokoban · August 1, 2015, 4:37pm

As some other people already told about it, the best solution is to update the audio drivers.
In my case, it was a Realtek “High Definition Audio Codecs”.
The current version is R2.79 and with it, Audacity v2.1.1 can run perfectly under Windows 10.

Gale_Andrews · August 1, 2015, 6:53pm

Thank you. It is still a second-best solution because those drivers http://www.realtek.com.tw/DOWNLOADS/downloadsCheck.aspx?Langid=1&PNid=14&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false are generic (not properly matched to your hardware).

And in most cases you must already have a Realtek device (as opposed to for example IDT or SoundMax) to use those Realtek drivers.

Gale

cryptoz · August 7, 2015, 12:05am

Latest realtek drivers rc2.79 install but changed nothing for Audacity. Installed 2.0.6 with no change. Installed 2.0.0 and Audacity works!

pryere · August 8, 2015, 2:47pm

can also confirm that version 2.02 works with Win 10.
missing all the latest features but it works! phew.

pljones · August 8, 2015, 9:38pm

I have on board audio and a Firewire Echo AudioFire4 soundcard. Both are recognised by Windows. MPC-HC plays to both. Reaper 4.78 reports:
WDM: AudioFire4
DirectSound, WaveOut: Mix, Realtek, AudioFire4
ASIO: AudioFire4, JackRouter
WASAPI: Realtek, AudioFire4

I was running Audacity 2.1.0. That hit the error reported here.
I upgraded to 2.1.1, no change. Same with Aug-08 nightly. 2.0.6 same; 2.0.5 same; 2.0.4 same.

2.0.3 works.

I was wondering if it was actually PortAudio but I’m more thinking it’s something to do with how the build is produced – the PortAudio version itself has remained V19 but the build date is that of the release. All I can see in the release notes for 2.0.4 that stands out is WASAPI.

Gale_Andrews · August 9, 2015, 1:58am

Thanks for the information.

The v19 is only the major version. For most (not all) Audacity releases, we update to the latest PortAudio v19 “snapshot” available at the time. So the PortAudio version is relevant, even though that is not apparent from the Audacity interface.

Changes we made in our PortAudio support could also be relevant.

This gets tricky because there are often winners and losers when PortAudio changes or when we tweak our support for PortAudio. For example, changes we made to PortAudio for Audacity 2.0.3 so as to make most devices’ Windows volume sliders move in tandem with the Audacity sliders caused some devices to reset their balance to zero when Audacity started up.

Hi,

Just to update, I finally found the updated Realtek drivers for my motherboard. Installing those has fixed the problem .
Motherboard: ASUS M5A99X-EVO-R20
I updated both the Realtek Audio and Network drivers.

Thanks,

– Peter

w3sz · August 11, 2015, 8:15pm

Running windows 10, I can confirm that when Audacity 2.1.1 or 2.0.6 is installed with the installer for version the error, “Could not find any audio devices. You will not be able to play or record audio. Error: Internal Portaudio error” occurs and Audacity does not work.

However, as was pointed out, version 2.0.2 when installed with the installer does work. No error occurs, and sound playback is as expected.

Thanks for pointing out that 2.0.2 works with Windows 10!

Great tip!

lezman · August 13, 2015, 12:27am

I was running version 2.1.0 on my desktop system and also had this problem when I did the Win10 upgrade. I’m using a Realtek onboard soundcard and a Generic USB mixing desk. Audacity came up with the “No Devices Found” error. Tried updating to 2.1.1 but no result. Did a driver update but my system already had the latest drivers. All other audio software had no problem playing or recording.

I did a system restore back to Win7 and all worked perfectly again.

Now that I’ve found this thread I’ll try the Win10 upgrade again and see if installing 2.0.2 gives better results…I’ll do it over the weekend so that I have plenty of time to reverse the process if it goes wrong again…unlike this morning when I did the restore in a mad panic!

Interesting to note, my laptop - which also uses Realtek sound drivers did NOT have this problem when upgrading to Win10.

I’ll post my results here after I do the upgrade on the desktop.

cyrano · August 13, 2015, 12:42pm

I’ve been following Win 10 update, mostly for audio. Installing the latest drivers for audio or even reinstalling existing ones seems to fix this error for most people.

It seems MS has done a great job on this one. Can’t remember any update that had so little problems…

Gale_Andrews · August 13, 2015, 1:03pm

How did you do the driver update? Going to the web site of the computer or motherboard manufacturer is the first choice method.
