Error while opening sound device ...

i’m using the last version of Audacity ,
Windows 7 Home Premium 64 bit
with Terratec DMX 6Fire USB.

The problem is that i can’t record with the mic connected to the external soundcard.
It gives me this error:
“Error while opening sound device. Please check the input device settings and the projects sample rate”

I’ve tried everything: changing the frequency (44, 48000 hz)
changhing the system in the device (windows directsound and MME)

no way. always the same message.

(on the other hand it can easily reproduce sounds with the soundcard, no problem with the output)

thank you in advice for your help!

Dig in the instructions and see if it requires ASIO driver software. Audacity doesn’t support ASIO.

The device does show itself in Audacity > Edit > Preferences > Devices > Recording, right?

Audacity > Edit > Preferences > Quality > Recording 44100, 16-bit should connect to almost anything. You also need to set Devices: Stereo.

Koz

in the soundcard manual at the end they say:
Software:
WDM driver for Windows XP SP2, Vista
ASIO 2.0 support
Windows only
Multiclient support ASIO and WDM
Windows only
WDM Kernel Streaming (e.g. Sonar)
Windows only
MME and DirectSound support
Windows only
Control panel for Windows XP SP2, Windows Vista and MAC OS 10.4 or higher
http://ftp.terratec.de/Audio/DMX_6fire_USB/Manual/DMX_6Fire_USB_Manual_GB.pdf

yes, the device show itself in audacity, but no variation for playback and recording:
device — > playback ---- > speaker dmx 6fire wmd aud
device — > recording ---- > speaker dmx 6fire wmd aud

Please post the content of Help > Audio Device Info… .

Also say what three section version number of Audacity you have (look at Help > About Audacity as requested in the pink panel above).

Your device works with Audacity on Mac OS X and Linux according to reports on this Forum.

There is no presumption multi-channel devices work with Audacity on Windows unless you build Audacity with ASIO support.

You could try Edit > Preferences: Quality and choose 24-bit Default Sample Format. Choose 192000 Hz Default Sample Rate.

Try all four inputs in Device Toolbar .

For each of those inputs, do you see only a choice of mono or stereo recording channels in the last box on the right in Device Toolbar? How it should work is that you get a choice of recording 1, 2, 3 or 4 channels and you would choose 4 channels to make sure you recorded the input you wanted. But you may need to build Audacity with ASIO support to see that.

If none of that helps, and you don’t want to build Audacity with ASIO support, the only other thing you can do is try the latest Audacity 2.0.6-alpha development build and choose WDM-KS host in Device Toolbar. WDM-KS does make a few multi-channel devices work correctly. But there is also a very small chance that WDM-KS could cause the computer to crash when you start Audacity.


Gale

I’ve tried,
nothing to do,
it doesn’t work …

another free software with ASIO support that you advice me to try ?

That doesn’t tell us what exactly you tried.

How many recording channels are in Device Toolbar?

Did you try 2.0.6-alpha with WDM-KS host?


Audacity supports ASIO, but you have to compile it to get that support.

You could try KRISTAL Audio Engine .
