Topic: RPM driver not working in Win 7 64 bit
I have an HDSP RPM which I've had for about 5 years, never had any problem with it on a Win XP laptop. The Cardbus card has the latest firmware (rev. 17). I just got a new PC with Win 7 64bit, and installed the latest WDM driver (3.24) downloaded from the RME downloads section. It appeared to install fine and everything went exactly as the instructions said. The Hammerfall DSP Mixer and Setting icons are at the bottom right of the taskbar notification area as they should be and they both seem to work fine, and correctly show input levels to the RPM, and allow me to mix inputs to output channels i.e. to actually route audio through the RPM (i.e. from ins to outs, but not from Windows itself).
So, everything seems correctly configured. But when I try to play audio through Windows, using Real Player or Windows Media Player, both will act like they are starting to play, but then just stay 'stuck' at 0:00 and the play time counter never advances and no audio comes out, and nothing shows up in the level meters in the Hammerfall DSP mixer. I tried quite a few different settings in the Windows Sound Control Panel Playback and Recording settings, and nothing makes any difference. And if try that play test sound button in the Sound Control Panel, it too doesn't play any audio, just sits there like it's wanting to start playing a sound but never does.
I installed Digicheck 5.32 and it will correctly show input levels if the "Hardware Level" option is checked under "Input Device Setup", but shows nothing if "ASIO" is checked. Therefore, it seems that the HDSP driver is just not able to get audio to or from Windows.
I also tried under Windows Sound Control Panel Playback and Recording settings to set the default playback and record devices to "Speakers (RME Hammerfall DSP Default Device)", "Analog (3+4)", "Analog (5+6)", "Virtual (1+2)", etc., and regardless, windows apps won't play, and I get no audio.
I also tried clicking Bypass under "I/O Box" and the setting of that makes no difference, still no audio either way. And I tried changing the Windows Sound Control Panel "Default Format" setting to 16 bit 44100 and to 24 bit 44100 and neither makes no difference. I also tried there changing "Exclusive Mode" to check or uncheck "Allow applications to take exclusive control", and another variant of also checking / unchecking "Give exclusive mode applications priority", and none of those combinations of settings make any difference. Still no playback.
Of course I also tried all the other obvious things. I tried rebooting several times; cold booting several times; reinstalled the driver; deleted the old driver and reinstalled; left the computer off for a bit between boots. So I think I have tried all the obvious things to get this to work and this seems to be a real issue with the RME driver not working properly with Win 7 64bit.
Ideas anyone? Has anyone used the RPM successfully with Win 7 64bit before?
(By the way, a small and probably unrelated bug I noticed is that in the Hammerfall DSP Settings screen it always comes up with none of the radio buttons on under "Input 3/4" selected. If you click one (e.g. "Line 0 dB"), then close it and reopen, same thing no radio button is checked. All the other settings on that screen seem to work fine though.)
