Linrad says No Soundcard Detected

[w3sz]

Hi All,

I was playing around with an 'extra' computer today that happens to have
32 bit Windows 7 installed [7600.16385.x86fre.win7_rtm090713-1255].

When I try to run Linrad 03.08 [stock pre-compiled version, installed
directly from the zip file on Leif's Linrad HomePage] I get the message
"No soundcard detected" upon typing "U" to set up the soundcards.

This computer has a Core2Duo Intel Atom D945GCLF2D motherboard with
onboard sound and the RealTek High Definition Audio sound driver. It
does not have another soundcard installed. The onboard sound works fine
for other apps, and the RealTek High Definition Audio sound driver shows
up fine under the Device Manager 'Sound, Video, and Game Controllers'
heading. Clicking on the device listing to determine the device status
gives the indication that 'The device is working properly', which it is
for other applications and Windows Sound. I didn't have this problem
[that I recall] when I used this same motherboard with Windows XP. I
can't go back and check that right now, however.

I am primarily using the computer with HPSDR hardware and PowerSDR, but
I wanted to run Linrad as well, as I need a very sensitive waterfall for
the application I have in mind, and Linrad has the best there is in this
regard.

I am sure this problem must be a Windows thing [or, alternatively, a
stupid-operator thing] and not a Linrad thing, and I notice that others
are happily using Linrad and Windows 7. So I am hoping someone else had
this problem and solved it.

Any thoughts anyone?

Thanks in advance, and

Presumably there is no WMME driver on your system.
The other types of drivers will be supported relatively soon through
Portaudio.
Here is some info about what is coming:

Presumably you can find the XP drivers for the RealTek High Definition
Audio and get Linrad running with them under Win 7. Not really recommended
because WMME drivers under Windows 7 use the horrible audiodg.exe:
